What is a solid-state battery? Many of our current electrolytes are liquid-based. This makes them heavy, flammable, corrosive and toxic. Solid-state batteries remove that corrosiv ...

Solid-state cells promise faster recharging, better safety, and higher energy density. They replace the liquid electrolyte in today’s lithium-ion cells with a solid separator. Honda, Toyota, and ...

Solid-state batteries can be over twice as energy-dense as current lithium-ion batteries. This means an EV’s battery pack would require fewer battery cells for the same capacity, and the pack ...

Solid-state batteries use a solid or semi-solid electrolyte, such as an alloy, polymer, paste, or gel, in contrast to the liquid electrolyte bath found in most conventional battery chemistries.

Solid-state batteries can be fully charged more quickly. Crucially, though, solid electrolytes are less dense, so a solid-state battery can be smaller and lighter than its lithium-ion competitor.
