- Commonly used secondary batteries include lead storage batteries, nickel cadmium batteries (NiCd), nickel hydrogen storage batteries (NiMH), lithium ion batteries (Li-ion), and lithium ion polymer batteries (Li-ion polymer). Secondary batteries offer both economic and environmental advantages over primary batteries that are used once and discarded.

Recently, the development of wireless communication technology has led to the popularization of portable devices, and there is also a tendency to wirelessize many kinds of conventional devices, and the demand for secondary batteries is exploding. In addition, hybrid vehicles and electric vehicles have been put to practical use in terms of prevention of environmental pollution, and these next-generation vehicles employ technologies that use secondary batteries to reduce value, weight, and increase lifespan.
