SiliconJoule

About

SiliconJoule is a private headquartered in Santa Clara, United States with approximately 50-200 employees specializing in Energy Storage.

SiliconJoule is a battery technology company that has reimagined lead-acid battery design by integrating silicon wafers into a bipolar architecture. The proprietary technology replaces traditional lead grids with processed silicon wafers, reducing battery weight by up to 35%, extending cycle life to 4X that of conventional AGM batteries, and improving dynamic charge acceptance by up to 5X. The innovation enables safe, recyclable energy storage with lower costs than lithium-ion while requiring minimal investment to integrate into existing lead battery manufacturing facilities. Applications span residential and office energy storage systems, automotive (24V/48V for drive-assist and start-stop), personal mobility vehicles (e-bikes, scooters), industrial equipment, golf carts, RVs, and reserve power systems. The company operates a licensing model, partnering with global battery manufacturers including East Penn Manufacturing, Crown Battery, Amara Raja Batteries, Luminous Power Technologies, and Pilot Battery Co. to scale production across multiple markets.
