US cell maker Amprius Technologies announced a new product platform called SiCore, an expansion of its silicon anode batteries range.
Amprius has also branded its existing silicon nanowire platform SiMaxx with its current product range of up to 500Wh/kg and 1,300Wh/l energy density.
The new SiCore batteries are based on a proprietary silicon anode material system, delivering high-energy-density silicon anode batteries that it claimed surpass current state-of-the-art graphite cell performance. The new silicon anode cell chemistry is designed to offer high energy density of up to 400Wh/kg and long cycle life of up to 1,200 cycles at full depth of discharge.
Dr. Kang Sun, CEO of Amprius Technologies, said customer feedback has been good and forecasts demand of over 100MWh over the coming years. Amprius has been sampling the SiCore products with customers for several months.
The company has an exclusive supply agreement with its partner Berzelius. This gives it exclusive rights to use the silicon anode materials to serve the US, Canada and Mexico. The SiCore batteries are currently manufactured by partners.
The SiCore product platform complements its SiMaxx silicon nanowire anode batteries and serves as a capacity bridge until the gigawatt-scale facility becomes operational. Amprius expects to produce both SiCore and SiMaxx batteries at its gigawatt-scale factory in Brighton, Colorado.
The 775,000 square foot Colorado facility is set to be operational in 2025. It is being built in phases, starting with an initial 500MWh with potential for up to 5GWhGWh.
