Amprius Reveals High-Power Lithium-ion Battery for Enhanced EV Performance

Amprius Technologies, a leading innovator in battery technology, has announced the development of a new ultra-high-power, high-energy lithium-ion battery. This cutting-edge technology is set to revolutionize the aviation and electric vehicle (EV) industries. The new battery cell boasts a discharge rate of 10C and delivers an energy density of 400 Wh/kg, significantly enhancing the performance of electric aviation and EVs.

Why It Matters

The advanced battery technology is expected to have a profound impact on the electric vertical takeoff and landing aircraft (eVTOL) and unmanned aerial vehicle (UAV) industries. The high-power output of the new cell will provide unparalleled propulsion power and energy, meeting the rigorous demands of takeoff, cruise, and landing. It also promises to extend flight range by up to 50% and increase payload capacity.

Key Points

  • The new battery cell’s capabilities also extend to high-performance EVs, potentially enabling them to achieve 0 to 60 mph acceleration in less than 1.5 seconds, setting new performance standards in the EV industry.
  • The cell’s power density is 3500 W/kg in standard discharge conditions, and it can exceed 4400 W/kg at lower depths-of-discharge.
  • The cell 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 new ultra-high-power cell also features ultra-fast charging (UFC) capability, reaching 80 percent charge in approximately six minutes or less.

Bottom Line

Amprius Technologies continues to pioneer in the field of battery technology, with its latest innovation set to transform the aviation and EV industries. The company plans to have samples of this cell available for customers by the end of 2023, with commercialization slated for early 2024.
