Presentation Summary

Zenlabs has developed advance lithium ion cells using silicon-based anode that exhibit high specific energy and fast charge characteristics. Our proprietary silicon-based anode when paired with Nickel rich cathode can enable 300 to 400 Wh/Kg of specific energy. Pouch cells having 315 Wh/kg have cycled over 1000 times at 100% DOD at 1C rates. Pouch cells exhibit 90% capacity recovery under the standard 15-minute charge test and have cycled over 700 times when cycled at fast charge condition of 4C charge and 1C discharge.
