Battery cell company Zenlabs Energy has announced the results of energy and power testing on its new large-format pouch cells as part of broader testing performed by independent third-party test lab Energy Assurance.

Designed for the electric aviation market, the new large-format cells have a 32 Ah capacity. In 12C rate testing involving about 394 A, 30 second pulses and a temperature of 30 degrees Celsius, Energy Assurance confirmed that the cells have a specific energy of 327.5 Wh/kg and a power rating of more than 3,000 W/kg.

Energy Assurance continues testing the cycle life of the cells. Zenlabs says its own testing showed more than 700 cycles at a 1C rate. The test report on the energy and power of the cells is available here.

“The high specific energy, high power and rapid charging capabilities of Zenlabs’s battery cells make them uniquely suited for the electric aviation market, which requires each of these capabilities to extend flight times, power take-offs and landings and enable different flight use cases,” said founder and CEO of Zenlabs Dr. Sujeet Kumar. “Accordingly, we believe that our proprietary pre-lithiated silicon anode and high-performance battery cells will be a real game changer for the electric aviation market.”
