Beyond the Liquid Cell
Solid-state, sodium-ion, and the future of the global power grid.
- The Upgrade
Solid state of mind
Traditional batteries use a liquid electrolyte, which is flammable and unstable. Solid-state batteries replace this liquid with solid materials like ceramics or glass.
- Mechanism
A firewall for ions
Solid electrolytes act as both a separator and a highway for ions. This prevents the formation of dendrites that pierce liquid separators and cause fires.
- Safety Leap
No more fires
Because solid-state materials are non-flammable, they eliminate the risk of thermal runaway. This allows for simpler, lighter cooling systems in electric vehicles.
