About

Sila Nanotechnologies is a battery materials company that makes a silicon-based anode powder to replace graphite in lithium-ion cells. Its flagship product, Titan Silicon, is a drop-in nanoengineered silicon composite that can replace 50-100% of the graphite in a conventional anode and raise energy density while remaining compatible with existing cell manufacturing lines. Founded in 2011 in Alameda, California, the company shipped a commercially available silicon anode in consumer devices such as the WHOOP 4.0 band and is scaling automotive-volume production at a plant in Moses Lake, Washington, with partners including Mercedes-Benz and Panasonic Energy.

Titan Silicon is a powder engineered as a direct drop-in for graphite, so cell makers can adopt it on existing lithium-ion manufacturing equipment instead of retooling; Sila pairs that with its own US-based Moses Lake plant for automotive-scale supply.

Product

Titan Silicon

Advanced battery materials

A nanoengineered silicon anode material, supplied as a black powder, that replaces some or all of the graphite in lithium-ion battery anodes to increase energy density.

  • Silicon-dominant composite replacing 50-100% of graphite in the anode
  • Drop-in compatible with existing lithium-ion cell manufacturing
  • Lower weight and smaller volume than an equivalent graphite anode

Built for

Lithium-ion cell manufacturers and OEMs in electric vehicles, consumer electronics and wearables
