The Big Challenge

Despite increased capacity potential and other advantages, silicon-based anodes swell upon lithiation, resulting in particles fracture and subsequent solid electrolyte interphase (‘SEI’) instability. This challenge results in decreased capacity and reduced long-term durability of the lithium-ion battery.

Existing application of silicon batteries have been limited due to such swelling concerns. Although silicon anodes remain the important performance driver for the electric vehicle market, their value has yet to be fully unlocked.

SiG^TM – Silicon-Graphene Technology

VoltaXplore focused on technology aimed at restricting silicon swelling altogether. Our technology wrap Graphene around Silicon particles to form hard shell that contains the expansion of silicon.

Other technologies aimed at managing silicon swelling in various environment using scaffolding structure or other, making cells inherently more susceptible to potential particle fractures.
