Advanced High Silicone Anode Prismatic Battery Production in California
Document Type
NOE - Notice of Exemption
Document Description
The purpose of this Agreement is to fund the build-out of a Low-Rate Initial Production (LRIP) pilot line for silicon anode prismatic batteries with up to 30% greater energy capacity compared to traditional graphite-based batteries. These batteries increase the lithium (Li) capacity - and therefore energy density - of the anode by alloying silicon (Si) with lithium while still mitigating lifecycle risks that are found in many Si anode technologies. This battery also incorporates a patented internal fuse, increasing the safety of the battery during short-circuit events. During the project, a production line will be built capable of manufacturing 500 cells/day while maintaining 90% yield.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit. 14, § 15301
Reasons for Exemption
This project is exempt under CEQA Guidelines section 15301 because it will consist of minor alterations to an existing structure, involving negligible or no expansion of existing or former use. Specifically, this project will use available space in an already existing structure that is zoned for industrial manufacturing, covers 23,000 square feet, and is currently used for prismatic battery cell production. The recipient’s facility currently relies on manually operated machines which can produce no more than 50 cells per day. To effectively scale production for LRIP, this project will install additional equipment including an automatic electrode die cuter, electrolyte filling machine and prismatic laser sealer. All installation will be performed within the shell of the existing building. This new equipment will only use approximately 200 square feet of floor space, does not use any water or other liquids as coolers, and will not cause any changes in facility design or operation.
