Amprius Technologies is expanding its portfolio of silicon anode batteries aimed at transforming electric mobility with the introduction of its SiCore product platform. The company 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.
SiCore batteries use a proprietary silicon anode material system, offering high-energy-density silicon anode batteries that, Amprius states, outperform current graphite cell performance. The new silicon anode cell chemistry has been designed to offer high energy density of up to 400Wh/kg and an extended cycle life of up to 1,200 cycles at full depth of discharge.
Developed in collaboration with Berzelius (Nanjing) Co (a formerly affiliated company then known as Amprius (Nanjing), the SiCore silicon anode battery’s performance has been validated across various electric mobility applications. Initial samples have received positive feedback from customers, Amprius says, with forecasts of demand exceeding 100MWh over the coming years.
Through an exclusive supply agreement with Berzelius, Amprius has the rights to use these silicon anode materials in the USA, Canada and Mexico. SiCore batteries are currently manufactured by toll manufacturing partners, serving 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 Colorado.
Dr Kang Sun, CEO of Amprius Technologies, said, “Leveraging our proven track record of delivering the industry’s highest commercially available energy density silicon anode lithium-ion cells to esteemed aviation customers such as AALTO/Airbus, AeroVironment, BAE Systems, Teledyne FLIR, and the US military, Amprius sees a significant opportunity with SiCore to broaden our silicon anode battery solutions today and to advance more applications across electric mobility.”
John P Aldana, senior director of Switchblade 300 Product Line, Loitering Missile Systems, at AeroVironment, said, “We are excited to have been part of the initial testing with Amprius as they evaluated launching the SiCore battery, designed to significantly extend the travel range and cycle life of anything that flies or moves compared to currently available commercial batteries.”
