Micro-battery

0399221-101

[DEFINITION]
An uｌtra-small cell that convert chemical energy to electrical energy.

[DESCRIPTION]
In the field of micromachines where energy supply is an important issue, research is focusing on such topics as micro-batteries, micro-generators, microwave energy supplies, propagation of vibrational energy, and optical energy conversion devices. Micro-battery research, which improves the energy density per volume and miniaturizes battery size, is developing thin film processes and machining technologies. In particular, R&D into packaging technology and electrolyte materials is advancing. As the volume of micromachines is small, rechargeable secondary batteries are desirable, and research is focusing on metal/hydrogen secondary batteries or lithium-type secondary batteries.
