Dry cell

cells use an electrolyte in the form of a paste that has impregnated a paper substrate, which also serves as a separator

Dry cells are a type of chemical cells.[1] Dry cells are commonly used today in the form of batteries. Dry cells are used in many electrical appliances.[1] Most dry cells are not truly dry; they still contain a liquid electrolyte, but it is immobilized in a paste or gel. Several truly dry, or solid-state, batteries have been developed, but none are commercially available yet.
