How are batteries classified?

Batteries can be classified according to their chemistry or specific electrochemical composition, which heavily dictates the reactions that will occur within the cells to convert chemical to electrical energy. Battery chemistry tells the electrode and electrolyte materials to be used for the battery construction.

What are the different types of batteries?

Batteries are grouped under two broad categories, aptly called primary cells and secondary cells. Sometimes they are referred to as primary batteries and secondary batteries. In a nutshell, a primary cell refers to a single-use battery that is not rechargeable. Think of disposable batteries that you discard upon depletion.

What is a primary battery?

Primary batteries are “dry cells”. They are called as such because they contain little to no liquid electrolyte. Again, these batteries cannot be recharged, thus they are often referred to as “one-cycle” batteries.

What are the different types of primary batteries?

Primary batteries come in three major chemistries: (1) zinc–carbon and (2) alkaline zinc–manganese, and (3) lithium (or lithium-metal) battery. Zinc–carbon batteries is among the earliest commercially available primary cells. It is composed of a solid, high-purity zinc anode (99.99%).

What is a battery designation system?

The current designation system was adopted in 1992. Battery types are designated with a letter/number sequence indicating number of cells, cell chemistry, cell shape, dimensions, and special characteristics. Certain cell designations from earlier revisions of the standard have been retained.

Are all batteries created equal?

Battery Classifications – Not all batteries are created equal, even batteries of the same chemistry. The main trade-off in battery development is between power and energy: batteries can be either high-power or high-energy, but not both. Often manufacturers will classify batteries using these categories.
