Amprius Technologies a producer of lithium-ion batteries with its Silicon Anode Platform, has launched its newest “ultra-high-power-high-energy lithium-ion battery”. The company says the cell achieves an impressive discharge rate of 10C while delivering 400 Wh/kg energy density.
According to the press release “The cell’s power output brings benefits to the electric vertical takeoff and landing aircraft (eVTOL) and unmanned aerial vehicle (UAV) industries. It extends flight range by as much as 50% and increases payload capacity. The new cell’s capabilities extend to high-performance EVs, potentially enabling them to achieve 0 to 60 mph (0 to 97 km/h) acceleration below 1.5-seconds.
“With a power density of 3500 W/kg in standard discharge conditions and a maximum power exceeding 4400 W/kg at lower depths-of-discharge, the cell’s usable discharge capability is extended. It supports high current pulses at low states of charge without going below the lower cut-off voltage, namely 3000 W/kg at 30% depths-of-discharge. The combination of high energy density and high-power density reduces battery weight and volume, leading to extended range, reduced charging frequency, and lower operating costs.
“In addition, the new ultra-high-power cell boasts an ultra-fast charging (UFC) capability, reaching 80 percent charge in approximately six minutes or less, transforming mission-critical operations with swift turnaround times.”
Amprius expects to have samples of this cell available for customers by the end of 2023 with the commercialisation of the new cells slated for early 2024.
