High Energy, Fast Charging Lithium Ion Cells Enabled By Pre-Lithiated Silicon Anode

Ionblox has overcome poor cycling and high swelling associated with Silicon anode based lithium-ion cells. Ionblox has developed large format pouch cells using pre-lithiated silicon anode that exhibit high specific energy, fast charge, high-power, and long cycle life. Our patented pre-lithiated silicon anode when paired with Nickel rich cathode enables Lithium-ion cells to have specific energy from 330 to 400 Wh/Kg. Our Lithium-ion Pouch cells have cycled over 1500 DST cycles following USABC test protocols. Pouch cells exhibit 90% capacity recovery under the standard 15-minute charge test and have cycled 1000 times when cycled at fast charge conditions of 4C charge and 1C discharge. Cell performance has been validated by US national labs in the USABC program.
