Enevate Corporation’s Post

"The anode, with 70% silicon, is made by Enevate Corporation....." Li-ion cell makers use to add 2-7% (weight percentage) of Si to the graphite anode. Si is great because its specific capacity is up to 4200 mAh g −1 compared to only 372 mAh g −1 for graphite, but Si changes its volume by 300% during charging and discharging. I hope that you know what it means for the structure of li-ion cells - the high risk of cracked anode or cathode current collectors. That is why serious battery makers avoid adding too much Si, because they do not want to risk battery packs in fire.

A battery with silicon-dominant anode? Please explain.

Would you have a real world test report?

Cool. Not a motorcycle rider… can I pop the battery out and install in my Tesla?

Seems from the comments here that people don’t really understand silicon-based anode technology. Perhaps I should make a video dispelling these misconceptions! Thanks for capturing this pivotal advancement toward the commercialization of Si anode cells Steve LeVine !!

Great work achieved with this bike and placing such battery tech inside! Well done to all who worked on this!👏🏻 I moderate the “cheap” silicon, one cannot use standard metallurgical grade known as commodity and priced few $/kg, but rather a high purity specialised silicon which must be pulverised to the right particle size distribution. It takes a lot of energy and the right proprietary technology such as the one held by Ferroglobe to supply such silicon metallurgical grade in respect with the environment.

Vroom!
