The battery has a different classification method, classification method can be divided into three categories

The first category: classified by type of electrolyte include: alkaline batteries, mainly potassium hydroxide electrolyte solution-based battery fire: such as: alkaline manganese batteries (commonly known as alkaline manganese batteries or alkaline batteries), nickel-cadmium batteries, nickel-metal hydride batteries. Acid batteries, mainly in aqueous sulfuric acid medium, such as zinc-manganese batteries (and some consumers also called acid batteries), seawater batteries; organic electrolyte batteries, battery mainly organic solution medium, such as a lithium battery, lithium ion batteries.

The second category: by the nature of work and conditions for storage division includes: a battery, also known as primary cells, that can not rechargeable batteries, such as zinc-manganese batteries, lithium primary batteries; secondary battery to charge batteries, such as nickel metal hydride batteries, lithium ion batteries, nickel-cadmium battery; lead-acid batteries used to refer to the battery is a secondary battery; fuel cells, namely the active material in the battery when the battery is continuously added, such as hydrogen fuel cells, etc. from the outside; reserve batteries, which are not in direct contact with the electrolyte when the battery storage, until the battery, before adding electrolyte battery, also known as silver magnesium seawater batteries.
