GDI proclaims third-party cell verification of its 100% silicon anode


Battery-makers are eagerly researching methods to include silicon, which may doubtlessly retailer 10 occasions as a lot power as graphite, into anodes. Now silicon anode specialist GDI says it has developed a 100% silicon roll-to-roll processed anode for next-generation batteries, doubtlessly enabling graphite-free battery cells that ship far increased power density, sooner charging and larger security than present cells.

GDI’s anodes have demonstrated particular capability of over 3,200 mAh/g in third-party testing.

The brand new anode makes use of a 100% silicon structure, bonded on to copper alloy foil from Carl Schlenk, a supplier of high-performance metallic foils.

In partnership with plasma tools and glass manufacturing specialist AGC, GDI has demonstrated MWh-scale roll-to-roll manufacturing on industrial tools. The corporate calls this a proof of idea to point out that its silicon anodes will be produced at GWh scale, delivered on to cell makers and built-in instantly into current cell manufacturing strains.

Navitas nail penetration testing demonstrated spectacular resistance to thermal runaway. After leaving a nail pierced by way of a 3.5 Ah cell with a GDI anode for 10 hours, there was no fireplace, no smoke, and temperatures solely elevated by 10° C.

GDI says it’s already executing preliminary product improvement partnerships in medical and protection markets, and is concurrently finishing up preliminary testing for the premium EV section.

“Our mission at GDI is to ship a 100% silicon anode that may be built-in into current battery manufacturing, enormously reduces GHG emissions from the anode manufacturing, and scales quickly on cutting-edge industrial tools,” stated GDI founder and CEO Rob Anstey. “In partnership with AGC and Navitas we’ve completed all three. The subsequent step is to point out our anode can allow EV batteries that energy autos with >500 miles of vary, permits them to cost 250 miles in quarter-hour, a whole lot of occasions, and improves security. GDI and AGC have developed a transparent roadmap to gigawatt-scale manufacturing by 2028, in order that this know-how can be utilized in tens of 1000’s of high-performance autos by 2030.”
