Enovix is readying its advanced silicon-anode lithium-ion battery facility for production

 FREMONT, Calif—Enovix Corporation is installing third-generation equipment at its 68,650-square-foot facility in Fremont, California, to prepare for production of its advanced silicon-anode lithium-ion battery, the company said in a release. The company said it expects to start production in the third quarter of 2021, undertake customer facility qualification in the fourth quarter, and realize revenue in the first quarter of 2022.

“Production and commercialization are the milestones that distinguish a successful enterprise from aspirational claims, and Enovix is building the first advanced silicon-anode lithium-ion battery production facility in the U.S.,” said Harrold Rust, Enovix co-founder and CEO, in the release. “We believe the batteries we produce will provide the energy density our customers need to continue mobile device innovation, and we’re creating jobs for people in our local community and throughout the Bay Area. We’ve added about 60 new people over the past year, and we expect to add about 60 more as we fully ramp our production through 2022.”

Enovix (www.enovix.com) has designed, produced, and shipped an advanced silicon-anode lithium-ion battery that is reported to combine increased energy density and high cycle life. Its proprietary 3D cell architecture enables Enovix to use silicon as the only active lithium cycling material in the anode. The company said it has advanced battery development agreements with “several category-leading mobile device companies.”

The Enovix production process is designed to leverage much of the conventional lithium-ion battery manufacturing process. It includes the same electrode fabrication process and the vast majority of pouch packaging and formation, to which Enovix adds pre-lithiation. Enovix has applied an innovative approach, the company said, developing proprietary production tools that are “drop-in” replacements for the winding or cut-and-stack tools in conventional pouch,  lithium-ion battery cell assembly.

For its work in battery design and production, Enovix (www.enovix.com) has been awarded 89 patents and has more than 50 applications pending, the company said.
