Reinforced Microporous Silicon Alloy Anodes for Next Generation Lithium Batteries

In Phase I Navitas demonstrated a novel high capacity anode material based on reinforced microporous silicon alloy. The key innovation in this project is a process that produces a microporous silicon reinforced by a small weight fraction of electrochemically inert ceramic. This process is scalable and uses low-cost reactants and precursors. The ceramic both extends cycle life and enhances safety. In Phase II, Navitas will scale and incorporate the anodes into prototype cells at TRL 6. The cells will be assembled into 26V, 30Ah aviation battery prototype. The primary customer will be defense and civilian aircraft in which there is a premium value on battery weight, safety and total cost of ownership. Early adopters will include soldier portable, small unmanned aerial systems and consumer electronics manufacturers who put a premium value on weight or run-time and will accept modest cycle life.
