[Advances in Implantable Medical Device Battery].

In recent years, active implantable medical devices become a hot spot of the medical device industry. There are still many problems in terms of reliability, capacity and life expectancy because of the subject to material and technical constraints. This review summarizes the development history and current status of the batteries used in active implantable medical devices, and describes the development and problems of zinc-mercury batteries and lithium batteries. The flexible batteries and bio-energy battery and other new battery technology are also expounded. The future of active implanted medical device battery is bound to miniaturization, flexibility, rechargeable direction.
