| Abstract: |
Navitas proposes 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. The process is scalable and uses low-cost reactants and precursors. The ceramic both extends cycle life and enhances safety. 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. |
| Benefits: |
Next generation lithium ion batteries incorporating the proposed novel high energy anode architecture technology will provide a competitive advantage to end users through improved battery energy density and cost, reducing the battery size and price vs. SOA lithium ion batteries. A 1000 mAh/g anode would potentially increase battery energy density by up to 30%. As cycle life is extended and costs are reduced through scale-up, the technology will ultimately capture a share of the electric vehicle battery market. Silicon-based anodes may also offer a safer alternative to lithium metal in lithium sulfur batteries which will require higher anode capacity than graphitic carbon can offer. |
