Solid-state battery

Definition

A solid-state battery is a type of battery technology that uses a solid electrolyte instead of the liquid or gel electrolytes found in traditional batteries. This design leads to higher energy density, improved safety, and greater longevity, making solid-state batteries a promising alternative in advanced energy storage systems. The unique features of solid-state batteries also impact their characterization and performance metrics compared to conventional battery technologies.

5 Must Know Facts For Your Next Test

1. Solid-state batteries can potentially provide up to two to three times the energy density compared to conventional lithium-ion batteries, allowing for lighter and smaller devices.
