Dry cell

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.

Types of dry cells

Primary cells are not rechargeable.[2] They have to be thrown away after their chemicals are used.

Secondary cells are rechargeable. They can be used again.
