Battery-operated device , in particular implantable medical-electrical device

摘要

The battery-operated device (11) has an electrically operated functional unit (12) and an electro-chemical voltage source, which are accommodated together in a gas density device housing (14). The electro-chemical voltage source has electrolyte based on an ionic liquid, and coating-free plastic battery housing. The electro-chemical voltage source is formed as a lithium battery (10). The battery housing is made of polyethylene or polycarbonate.
