Battery classification has different methods, and its classification can be divided into three main categories:
Category I: According to the type of electrolyte, including: alkaline batteries, electrolytes mainly potassium hydroxide solution based battery: such as: Alkaline zinc manganese batteries (commonly known as alkaline manganese batteries or alkaline batteries), cadmium nickel batteries, ni-MH batteries, etc.
Category II: According to the nature of work and storage methods include: A battery, also known as the original battery, that is, batteries can not be recharged, such as zinc manganese dry batteries, lithium-ion batteries, two times the battery, you can charge the pool, such as Ni-MH batteries, lithium off batteries, cadmium nickel batteries, battery habit refers to lead-acid batteries, but also two times the battery; That is, the active material in the battery work only continuously from the outside of the battery, such as hydrogen and oxygen fuel cells, storage batteries, that is, batteries stored without direct contact with the electrolyte, until the battery is used, only to add electrolyte, such as magnesium silver battery also known as seawater batteries.
Category III: According to the battery used positive and negative material division includes: Zinc series battery, such as zinc manganese batteries, zinc silver batteries, Nickel series batteries, such as cadmium nickel batteries, nickel hydride batteries, such as: Lead series batteries, such as lead-acid batteries, lithium-ion batteries, lithium manganese batteries, manganese dioxide series batteries, such as zinc manganese batteries, alkaline manganese batteries, etc. Air (oxygen) series batteries, such as zinc empty batteries.
