This is very good news

@ordos Very nice, they really are proactively pursuing the battery space. Using this proprietary silicon additive to existing graphite anodes without any other modifications would have low entry barrier and could have any of the existing battery manufacturers lined up for significant battery performance improvement with zero investment, except buying the materials.

@Sabbath "Preliminary testing demonstrates a capability to improve performance by more than 14% without noticeable first-cycle degradation" - from my understanding; the first few cycles of a cell is when a cell is most prone to swelling due to Si in the anode, so if the cell hasn't started swelling and/or degrading within its first few cycles, the cell will most likely will meet

@MajicT Yeah, 10% is generally the maximum accepted limit of Silicon in battery anodes due to the expansion of the silicon with charge-discharge cycles, so it makes sense they'd start with that. But if they've managed to mitigate the issue with their engineered SiOx then that limit no longer needs to apply :)

renaissance Although other companies are also using these types of batteries, 18650 are used by Tesla in their “Model S, Model X and Roadster” EV and in their Powerwall 1. And 21700 are used in their “Model 3 and Model Y” EV as well as in their Powerwall 2. Bernard shaking hand with Elon certainly could be a near future possibility.
