Definition: solid state battery


A battery that uses a solid electrolyte. Solid state batteries are expected to be the next advance in batteries because they require less built-in safety technology than liquid electrolytes, which are flammable. As a result, solid state batteries are more compact, have longer battery life and recharge more quickly.

A Game Changer?
Although the technology has been around for years, solid state batteries have been incredibly expensive to produce, even though the components are easier to put together. However, research and development in the 2010s continued to lower the price, and solid state batteries are expected to power electric cars in the future. If successful, solid state batteries may have a major impact on the EV industry because pundits claim that charging takes half the time of lithium batteries. See electrolyte, batteries and electric vehicle.




Liquid vs. Solid State
Liquid electrolyte batteries are more complicated to make because the cathode and anode must float within the electrolyte (the substance that oozes out of old batteries). Solid electrolyte batteries can be manufactured flatter and easier.
