Most battery-powered devices, from smartphones and tablets to electric vehicles and energy storage systems, rely on lithium-ion battery technology. Because lithium-ion batteries are able to store a significant amount of energy in such a small package, charge quickly and last long, they became the battery of choice for new devices.
A new technology on the horizon has been receiving a lot of attention recently: solid-state batteries. As the name suggests, solid-state batteries do not need liquid electrolytes. Their basic structure is the same as a lithium-ion battery, but because they do not use liquids, solid state battery packs can be lighter, safer, and much more compact.
Worldwide, researchers are working to adapt the standard lithium-ion battery to make versions that are better suited for use in electric vehicles because they are safer, smaller, and lighter—and still able to store abundant …
