Solid-state batteries

Lithium-ion batteries have been revolutionary, powering devices from smartphones to large energy storage systems.

However, they use a liquid electrolyte to move charged lithium ions between the anode (negative side) and cathode (positive side).

This design has significant drawbacks, including a risk of fire due to the flammable liquid.

The article highlights that even travelers boarding planes in the last decade have encountered these safety issues.

Additionally, lithium-ion batteries are limited in how fast they can charge, how long they last, and how much energy they can store in a given space.

These limitations have driven interest in alternative battery technologies, particularly solid-state batteries, which replace the liquid electrolyte with a solid material like ceramic or polymer.
