Silicon has long been heralded as the next important anode material since it can theoretically store more than twice as much lithium as graphite anodes used in nearly all Li-ion batteries today. We will share how Enovix’s stacked cell architecture solves the four technical problems of silicon, producing a 100% active silicon anode battery designed to deliver high-energy density, as well as how Enovix is scaling-up in order to power the technologies of the future.

The electrification of everything hinges on commercial-scale battery technologies with higher energy density and faster charging. Group14 Co-Founder and CTO Rick Costantino will discuss why OEMs are tapping silicon to meet rising e-mobility demands – highlighting the transformational capabilities of Group14’s flagship technology, SCC55 – and how Group14 is scaling manufacturing through its modular approach. We will share insights from case studies with partners Molicel and Sionic Energy and dive into near-future applications, including EVs.

Adopting 3D novel current collector architecture is beneficial for any battery chemistry, and for many emerging anodes like silicon, Li-metal, and graphite, it can be a game-changer by solving their key challenges and limitations. No matter how high the anode energy is, the cathode must match it. By shifting to 3D current collectors, high-energy anodes can be put into batteries with cathodes that can match their energy density levels and deliver a safer, more stable battery.

Ultra-thin lithium metal is needed for next-generation anodes, including both silicon and lithium metal anodes. For silicon, lithium metal is needed to eliminate silicon’s first-cycle capacity loss, which unlocks fast-charge, dense batteries for longer range. For lithium-metal anodes, the lithium metal must be extraordinarily smooth to prevent dendrites and achieve higher density. Our ultra-thin lithium metal is meeting requirements for next-generation anode to enable improved EV and eVTOL performance.
