To understand what a solid-state battery is, we need to first look at existing battery technology first. Most modern EVs are equipped with Lithium-Ion batteries, with separators within its cells to keep their anodes and cathodes apart. The entire assembly is then immersed in a liquid electrolyte solution.
This leaves the pack vulnerable to damage due to temperature changes, as well as the potential for catastrophic failure when punctured.
Solid-state batteries are far more stable. The basic architecture remains the same. However, the liquid electrolyte here has been swapped out for a solid replacement. These batteries are also slightly simpler than existing units, as they do not require a separator between their cathodes and anodes.
