Solid-state batteries

Definition

Solid-state batteries are a type of battery technology that replaces the traditional liquid or gel electrolyte with a solid electrolyte, enhancing safety and performance. This innovation leads to increased energy density, longer lifespan, and reduced risk of leakage or fire, making them particularly suitable for demanding applications such as underwater robotics.
