Silicon anode is a very important technology for batteries. Silicon can link to more Lithium ions improving battery performance (higher volumetric and gravimetric capacity).
Some today batteries on the market already include Silicon-doped anode but they cannot fully benefit from this technology because their doping is limited (<5%).
The challenge is to limit its expansion (up to 300% in volume) when linking with Lithium. This limits the doping amount and so the benefit of this technology.
3DBattery is able to incorporate 50% of Silicon! How is that possible? Our team has engineered a technology to wrap around the battery cells to keep the integrity of the silicon and limit the Silicon swelling
The result? Our Silicon-anode technology allows to lever the amount of Silicon doping giving higher energy and power density and a specific capacity as high as 3600 mAh/g (10x of what is achievable currently in the common graphite anodes).
