Thanks, Eric. 2023 is starting out to be a great year for SES. A few years from now, when our lithium metal battery technology is in mass production, I think we will look back and say, 2023 was a key turning point as we laid several crucial foundations. First, I'd like to give you an update on our three OEM JDAs. As we have discussed previously, we were the world's first lithium metal battery company to enter automotive A-sample JDAs, and we did so with GM, Hyundai and Honda. Our biggest value to them, in addition to deep material development capability, is the ability to build and test many large 100 amp hour lithium metal cells. With this ability, our ideas become data, and data become intelligence. Even Elon Musk tweeted after the Starship launch that high production rate solves many ills.
It's been more than a year now since our 3 A-sample lines have been up and running. One in Shanghai, China, and two in Chungcheongbuk-do, South Korea, producing and testing large 50 amp hour and 100 amp hour lithium metal cells. These are the most advanced and battle-tested large lithium metal cell production lines anywhere in the world. What a difference they have made. They provide a safe and reliable platform for us to test new ideas and make improvements to the technology. It is safe to say, as we have discussed on previous calls, we simply didn't know what we didn't know until we started making these large cells in higher volumes. Many of the manufacturing issues that we detailed have now been solved or are close to being solved. For example, ultra-thin lithium anodes wrinkling and tearing during large format rolling and lamination.
After three rounds of iterations and improvements on our A-sample lines and in collaboration with our equipment and material vendors, we have significantly improved this issue. We have even started testing new processes for anode lamination and believe we will completely eliminate these issues in future designs. Second, novel electrolyte solvents scale-up. While our material R&D team continues to develop new solvent molecules, our scale-up team has completed four different types of electrolyte solvents for production. Third, electrode stacking misalignment and overhead. Our approach of manufacturing lithium metal cells using lithium-ion process really paid off here as our team of experienced lithium-ion engineers quickly addressed this issue by borrowing from their lithium-ion stacked pouch cell experience. Fourth, powder formation during electrode punching. This is unique to our lithium metal anode, and we now have two teams working on laser and metal die approaches in parallel.
Understanding the fundamental mechanism, we will be able to choose the best solutions after fully understanding both approaches. Five, formation pressure and voltage stability. This is also unique to our lithium metal cell, and after three rounds of iteration and improvements and working with our vendor, we now have a solution that we will implement across our current equipment and future designs. Six, finding efficient ways to do image scanning on large format cells and developing proper ways to store, handle, test, and recycle lithium metal cells. This is a really interesting and important area that many companies don't pay enough attention to.
We are integrating imaging tools, including X-ray, CT, SEM, ultrasound, and others to our manufacturing and Avatar systems. We're also developing new tools such as large 100 amp hour lithium metal cell teardown robots, smart test boxes, and very sophisticated large cell testing and storage monitoring facilities, all to provide a safe environment for us to innovate and test cutting-edge ideas on large 100 amp hour lithium metal cells. Seven, our large cell Avatar prediction accuracy increased from 0% to 60% last year. In a recent experiment, our Avatar successfully predicted 18 out of 21 abnormal cells. That's getting pretty close to 90%. Furthermore, we significantly improved quality management through diligently working with our OEM partners. For example, our control plan went from about 200 control points to now more than 1,400 control points.
We are targeting more than 4,000 control points since lithium metal is a new technology. We want to fully characterize every little detail in the entire process. These issues could not have been addressed through simulation or discussion. They required extensive trial and error. That's what our 3 A-sample lines did, building and testing hundreds to thousands of large 100 amp hour lithium metal cells to perform a massive universe of experiments. I don't think any other lithium-metal battery company is capable of doing this. If you don't do this, you just can't push lithium metal forward. We didn't stop there. These 3 A-sample lines are already the most advanced in the world for large 100 amp hour lithium metal cell production.
We want to integrate all the learnings that we have accumulated and build a brand-new line, one that is a leapfrog at least one generation ahead of our three A-sample lines. This is our line four. line four will be for the next phase of automotive large 100 amp hour lithium metal cell development. Basically, A-sample. Compared to the current 3 A-sample lines, line four will have many of the new concepts, including Avatar integration and rigorous quality control plan built in from its design phase. The exterior facility build-out is already completed. We expect the dry rooms to be completed this summer and the equipment to start arriving this fall, and the entire line four to achieve ready-to-use status in the first half of 2024. This will be a key enabler for us to transition to B-sample, which we're still on track to achieve this year.
Lastly, I want to quickly address our stock price. Frankly, it's not something I think about every day. Recently, we had our one-year anniversary since listing on the NYSE, and we completed two procedural filings. One was the S-3, which allows us to fundraise in the future, although we have no plan to fundraise anytime soon. Another was the Form 4, where management, including myself, recently reported the sale of shares purely to cover taxes on vested RSUs. I, as the founder of SES, have never sold a single share other than to pay taxes or made a single dollar from our stock since I started the company 11 years ago. I just wanted to clarify these two issues in case there have been any misinterpretations. Anyways, I'm super excited about the progress that we're making. It was painful last year, but now it's fun again.
Our new line four will be a step change in our development roadmap and a major part of transition to B-samples. We will continue to keep you posted as we take additional steps to get line four up and running. With that, I'll hand the call over to Jing to review our financials.
Thank you, Qichao. Good afternoon, everyone. Today, I will cover our Q1 financial results and discuss our operating and capital budgets for full year 2023. In Q1, our operating expenses were $21.6 , an increase of 2.4 million from the same period last year. Stock-based compensation expense was $6.5 million in the quarter. We reported research and development expenses of $8.5 an increase of 4.4 million from the same period last year. This increase reflects higher personnel costs due to increased head count to support battery cell development, an increase in lab consumables and material supplies, an increase in development costs related to our advanced AI software and battery management systems, and increased facility cost.
Our gross R&D spend in Q1 was $11.7 million, which was offset by 3.2 million billed to our OEM partners, which are treated as contra R&D expenses. Our G&A expenses were $13.1 million, a reduction of 2 million from the same period last year. This decline resulted from a decrease in transaction costs incurred as a result of the business combination during Q1 of 2022, which was partly offset by an increase in personnel costs and professional fees to support our operations as a public company. During Q1, cash used in operations was $15.4 million. CapEx for the quarter was $6 million, reflecting payments for equipment and facilities. Looking at liquidity, our balance sheet remains very strong.
We ended Q1 with combined cash equivalents, and investments in marketable securities of $373 million. We continue to believe our liquidity is sufficient to get us to commercialization. For 2023, our financial guidance is unchanged. We continue to expect cash usage from operations to be in the range of $80-1 00 million and capital expenditures in the range of $50- 70 million. In total, we expect cash usage for the year in the range of $130- 170 million. This higher level of spending compared to 2022 is necessary to support our growth as we expect to transition from A-samples to B-samples in 2023. Significant areas of spending in 2023 continue to be for headcount, lab expansion, equipment, manufacturing facilities, and materials.
Lastly, SES became eligible to file a S-3 registration statement following the first anniversary of our business combination with Ivanhoe Capital Acquisition Corp. Our S-3 was filed with the SEC on April 25 and became effective on April 28, 2023. It includes a universal shelf registration, which will allow us the flexibility to raise capital from time to time, up to an aggregate $300 million. While the headlines related to these type of filings can be confusing, to be very clear, we have no near-term plans to raise capital. 2023 is shaping up to be an exciting year of growth for SES. We appreciate the support of our shareholders, employees, and OEM partners. With that, I'll hand the call back to Eric.
Thanks, Jing. Cole, you can now open the line for questions.
We will now begin the Q&A session. If you would like to ask a question, please press star followed by one on your telephone keypad. If for any reason you'd like to remove that question, please press star followed by two. Again, to ask a question, press star one. We will pause here briefly as questions are registered. Our first question is from Shawn Severson with Water Tower Research. Your line is now open.
Great. Thank you. Qichao, I wanted to touch a little bit on line four. You had mentioned in prior calls about bringing in-house a number of the manufacturing technologies, right? That there was some difficult challenging stuff, and you thought you guys could do it better yourself. I was just curious if you could lay out in line four, I assume those types of changes are being implemented, and maybe help me understand a little bit of the, of the things that are being done in that, in that particular line versus the existing.
Yeah, sure. Thanks, Shawn. In the first 3 lines, especially starting line 3, we started incorporating all the aspects, the cathode coating, anode coating, in-house. It's still fragmented, we still don't have a very systematic way of collecting data for Avatar. Also, the number of control points, we started out with just 200 and then now 300. It's hard to add all these additional sensors and increase the number of control points from just 200, 300 to 1,400. In line four, a couple of things. One is it will have every aspect, cathode coating, anode coating, anode lamination, stacking. Line four will be the first complete line in terms of our ability to make every aspect.
Also, from the design phase of line four, we already incorporate these 1,400 control points. Whereas in the older line three, we had 200, and then we added in a fragmented way to 300. In line four, from the beginning, it will have basically every aspect in-house. We're going to incorporate all the 1,400 control points from the beginning, and then all these sensors and the data will be compatible and then integrated with Avatar. It's really a, I would say at least one generation ahead of just the first three lines.
From a manufacturability standpoint and a cost standpoint, are there any big-ticket items that are still in your sights to target cost reductions for as you go through B and of course eventually into C? Is there anything in particular you'd point to that is a great opportunity for further cost reductions that we should monitor?
In the first three lines for A sample, the yield was always quite low, the yield wasn't really a consideration for A sample. Basically, A sample is just, let's build a cell, let's test the performance, let's not worry about yield as much. The cost is obviously not very meaningful because we don't have a rigorous way of controlling the yield. This line four and then B sample later will be the first line that basically in addition to all the performance, all the capabilities that we built based on the A sample, line four will be the first line that we will actually track yield. Line four will have significantly higher yield than the first three lines.
line four will be the beginning where we actually move into a phase where we actually yield actually becomes a very meaningful consideration in addition to the performance and then and the other considerations from a sample. Yield is a big consideration for lowering the cost.
Great. Thanks for that too, Qichao.
Thanks, Shawn.
Thank you, Sean. Our next question is from Winnie Dong with Deutsche Bank. Your line is now open.
Hi. Thanks for taking my question. My first question is also on line four. In the shareholder letter, it says that, you know, it would be critical to B-sample. The equipment will start to arrive in the fall, and then the line will be entirely ready for use in the first half of 2024. It also seems like you're still on track to achieve the transition to B-sample this year. I just wanted to confirm, if the transition to B-sample is or is not dependent on, you know, line four being fully ready. Also maybe an update on sort of like the latest timeline for that transition. Thanks.
Yeah. For example, back in 2021, when we entered into A-sample, the definition of entering into A-sample or B-sample is basically starting the process of developing B-sample. line four is going to be a key part of the process of developing B-sample. We will enter into B-sample this year, second half of this year. line four is part of that. It's not like we only start B-sample after line four is ready. No, we start B-sample, part of the work of B-sample is getting this line four ready. There will likely be line five, line six, right, for the 3 OEMs. line four will likely be the first line in B-sample.
We will enter into B-sample second half of this year.
Got it. To confirm, so far you've sort of indicated, you know, B- sample with one of the OEMs. Is that correct? Or if there's anything that changed in that regard?
Yes, I think we will enter into one first, and then the other two will come later. From a technical perspective, the requirements are quite similar. The capability that we built and the capability that we increase by having line four, that will be transferable across all the three OEMs.
Got it. If I can squeeze just one more in, this is more of a theoretical question. I guess if we fast-forward to, let's say, you know, 2026, in an ideal world with everything sort of like, you know, going to plan, understanding that it might not, right, most likely, you know, you finish the A-sample by end of 2024, and this A-sample takes maybe another 12 months or so sort of, you know, to finish. What would ideally have taken place by then in 2026? Would it be, you know, a client with a JV ideally, you know, up and running, or do you start the build-out at that time in the U.S.? I'm just trying to get an idea of sort of your internal roadmap, even with the understanding that, you know, it's not set in stone.
Yeah. Sure. We enter into B-sample second half of this year, and then 2024 next year. Towards end of B and beginning of C, that's when we basically sit down with the three OEM partners and also potentially their large scale battery manufacturer partners, and then sit down and then plan location and resource for C and SOP. A and B are sort of similar and then considered together in the pilot scale plant. Once you get to C and then start planning for C, then you also plan for SOP. I would say towards end of B. Now we are transitioning to B.
Next, when, say one year to 18 months from now, when we are transitioning to C, that's when we plan this North American site for lithium metal battery manufacturing as well as supply chain.
Got it. Thank you so much for taking my questions.
Thank you.
Our next question is from Timothy Johnson. Your line is now open.
Thank you very much. In the past, recent past, you mentioned, some work being done on the anode-free concept. Can you please update us on where you stand with that?
Sorry, can you ask the question again? The recent work on the anode, and then what, the second half?
On the anode-free, where you take out the lithium foil, and all of the lithium for the anode comes from the cathode upon charging.
Yes. On the anode-free design, it's one of the next-gen projects that we are exploring. All the lines that we're using, the 100 amp hour cell lines, the three lines for A-sample and then now line four, all these can be used for anode-free as well. We are actively building and also testing anode-free version of these 100 amp hour lithium metal cells. When I say 100 amp hour lithium metal cells, they come in different versions, anode-free version as well as excess lithium version. We do have the capability to test these. Perhaps later this year, we can disclose more data.
For now, the anode-free version of a 100 amp hour lithium metal cell, we primarily are considering these for drones and eVTOL, the urban air mobility applications, less so for the EV applications.
Thank you very much.
Thank you.
Thank you, Timothy. Our next question is from Dennis Hugh. Your line is now open. I'm not sure if Dennis has disconnected or not. There are no additional questions waiting, I'll pass the conference over to the management team for any closing remarks.
Yes. I think this past quarter and just Q1 after 2022. 2022, last year, was when we first built these large 100 amp hour lithium metal cells. People thought it was a big leap and then crazy to build these large lithium metal cells. It was really difficult, and we thought we were crazy too last year. Now this quarter, this year, things have turned around. A lot of things that we learned, now, finally things are coming together.
Line four is really the first time that we take all the learnings that we have from A-sample to JDA, and then putting them together, all the capabilities, all the knowledge, all the new ideas, and then turn new ideas into data, and the data into intelligence. We're really excited about 2023 and just the future capability. I mean, now it's only in line four. Imagine a year from now, we're on line seven, right? The first line for C-sample. I just think I'm just really excited about the progress and then just can't wait to share more good news with you guys.
That concludes the conference call. Thank you for your participation. You may now disconnect your line.
