Calendering

Compressing a dried electrode coating between rollers to set its thickness, density and porosity. It is one of the electrode-making steps in cell production.

Solid-state battery

A cell whose electrolyte is a solid rather than a liquid. It removes the flammable solvent and may allow a lithium-metal anode, but needs intimate solid–solid contact and, for most chemistries, stack pressure to keep it.

Stack pressure

Pressure applied to a cell stack, in production or in use, to keep its layers in contact. Solid-state cells depend on it, because ions can only cross where two solids touch.

Sulfide electrolyte

The solid electrolyte family with the highest conductivity — argyrodites such as Li₆PS₅Cl match liquids, and LGPS exceeds them — and soft enough to be pressed rather than sintered. Their weakness is reaction with moisture, which releases hydrogen sulfide.
