Amprius Technologies selects Colorado for its GWh-scale factory site
Lithium-ion battery manufacturer Amprius Technologies has signed a letter of intent to build a 775,000-square-foot facility in Brighton, Colorado. The factory is expected to be operational in 2025, and will be built in phases. The first phase will have an annual capacity of 500 MWh. Capacity could potentially be expanded to as much as 5… Read more »
Amprius’s Si-Nanowire anode shortens charging time
Battery manufacturer Amprius Technologies is on a mission to reduce EV charging times. The company’s Amprius Extreme Fast Charge feature is enabled by its proprietary Si-Nanowire anode, which is thinner and lighter than conventional graphite anodes, and has much higher conductivity due to the high electrical continuity between silicon and the current collector. The Si-Nanowire… Read more »
