The Investor Letter (with financials) and the Solid State Battery Landscape paper is on their website under Investors. The conference call and Q&A has been posted.
from Investor Letter:
“We are pleased to report for the first time that we have made 4-layer multilayer cells in the 30x30mm form factor, and we have now seen close to 800 cycles at 30°C with over 90% capacity retention at both C/3 and 1C rates – substantially similar to the single-layer cells we reported in December. We used 30x30mm cells, made from separators cut from our standard target commercial area separators, because it allowed us to effectively quadruple the number of test cells as we work to scale up our engineering line capacity.”
The Call covered the pilot facility in San Jose where their test batteries will be manufactured. Among Q&A topics addressed: comparison products out there, market focus of product, other interest from car manufacturers other than VW, location of full battery factory.
