3D Silicon Li-Ions Get $45 Million from Investors and Customers

April 07, 2020 by Paul Shepard

Enovix Corporation has secured $45 million in new funds to produce and commercialize its 3D Silicon Lithium-ion Battery. The funding sources include a major new strategic investor, current investors (including T. J. Rodgers and York Capital), and non-dilutive funding from market leading customers.

Harrold Rust, Enovix co-founder and CEO, said, "The composition of this round is a testament to the performance we've achieved and progress we've demonstrated towards production and commercialization of our silicon-based lithium-ion battery. Anchoring the round is a $25 million strategic investment from a leading California technology company. Present investors have added $10 million, and customers have contracted $10 million to develop batteries for specific products and to reserve production capacity."

Enovix will use the bulk of the funds to complete its Fremont, California high-volume battery production facility, where about 75% of the equipment and processes are identical to standard pouch lithium-ion battery manufacturing. Enovix has developed proprietary electrode laser patterning and high-speed stacking tools that replace the standard electrode winding process to increase production line Mega-Watt hour (MWh) capacity by 30%.

"We initially attracted customers when we sampled cells about a year ago with energy density over 900 Wh/l and full-depth of discharge cycle life over 500," said Rust. "As customers and investors visited our production site and saw our proprietary electrode laser patterning and high-speed stacking tools in action, their confidence in our production capability was sufficient to generate revenue and secure additional funding."

The facility is expected to produce batteries for delivery in late 2020 and to reach a run-rate of 8-million units per year as it ramps in 2021 and 2022.

Enovix has also signed new agreements with two additional portable electronics companies. The company now has agreements with four category leading customers to develop and produce silicon-anode lithium-ion batteries for portable electronic devices, worth an anticipated $250 million in annual revenue once fully ramped. Based on successfully deploying 3D Silicon Lithium-ion Battery technology in portable electronic devices, Enovix is now working with leading international automobile manufacturers to develop its patented battery technology for the electric vehicle (EV) market.

Initial R&D indicates that cells can achieve gravimetric energy density greater than 340Wh/kg at a cost equivalent to or below present industry forecasts. Enovix expects to supply the EV market within 5 years.

Enovix has developed a lithium-ion battery that incorporates a 100% active silicon anode using its patented 3D cell architecture to significantly increase energy density and maintain high cycle life. The company is backed by strategic relationships with Intel, Qualcomm and Cypress and over $200 million in venture, strategic and private funding. It has been awarded over 70 patents and has over 40 applications pending to create sustainable enterprise value and provide a competitive barrier for years to come.
