The company states: "We are happy to report that planned testing of 24-layer A0 prototype cells at one automotive customer is now complete, and final results are in line with what we reported in our last shareholder letter. Most cells performed very well, meeting performance targets on fast charge and generally showing good cycling capacity retention and high Coulombic efficiency, with capacity loss of less than 1% per 100 cycles; however, we have work to do to improve reliability as we transition from prototype to commercial product. We have already identified and begun executing a number of initiatives to improve the quality and uniformity of our materials and processes, which we believe will lead to better reliability as we continue to progress toward a commercial product. Similarly, on the consumer electronics front, we’re pleased that customer testing of zero externally applied pressure single-layer prototype cells is also complete, with the cells generally performing very well on a broad range of electrical performance and characterization tests, including cycle life, resistance, storage life, and tests at multiple rates and temperatures, though as previously discussed, we have work to do on reliability. As with the automotive 24-layer A0 tests, these single-layer cells displayed less than 1% capacity loss per 100 cycles. The results of these independent tests provide validation of what we have seen in our own labs. We continue to see consumer electronics as an attractive market, and our zero externally applied pressure capability gives us optionality to pursue consumer electronics alongside our automotive development efforts. We believe our technology presents an attractive set of properties for consumer electronics applications, and we continue to engage with some of the largest consumer electronics players in the world."
