Addressing the Four Challenges of Silicon Anodes

Silicon has long been heralded as the next important anode material. Silicon anodes can theoretically store more than twice as much lithium than the graphite anode that is used in nearly all Li-ion batteries today (1800mAh/cm3 vs. 800mAh/cm3).

Silicon’s high energy density, however, creates four significant technical problems that Enovix has solved:

1) First Charge Expansion

Enovix cells have a stainless-steel constraint system surrounding the cell that limits the battery from swelling. We also reorient the electrodes to face a small side of the battery to decrease the required constraining force.

2) First Charge Efficiency

Enovix has developed a “pre-lithiation” process during manufacturing to insert additional lithium source to top-off lithium trapped at formation.

Our batteries can do this practically because the additional lithium only needs to travel a short distance in our architecture to permeate the anode.

3) Cycle Swelling

Enovix manages swelling as a result of cycling with its integrated constraint, limiting swelling to as little as <2% cell thickness after 500 cycles.

4) Cycle Life

The Enovix integrated constraint keeps particles under constant stack pressure, limiting particles from electrically disconnecting and cracking.
