Eliminate Thermal Runaway
Several safety features, which are not obtainable with a conventional Li-ion battery structure, are achieved with our 3D cell architecture:
- The cell architecture allows for a ceramic separator that tolerates higher temperatures than the polymeric separator in a conventional Li-ion battery.
- Excess capacity in our patented silicon anode reduces the risk of lithium metal plating during overcharge conditions.
- Distributed collectors limit current if an electrical short occurs.
- A walled off cathode limits propagation of material breakdown.
In addition, high thermal dissipation of our 3D cell mitigates local cell hot spots. Collectively, features of our 3D cell architecture eliminate the danger of thermal runaway to avoid personal injury and property damage from an explosion or fire.
