The present invention relates to an active element for a battery whose material contains copper oxyphosphate and an additive improving the conductivity. The proportion of the additive improving the conductivity in the material is between 3 and 7 wt. %, preferably between approximately 3 wt. % and approximately 5 wt. %, and the proportion of the copper oxyphosphate in the material adds up to 100 wt. %. The invention additionally relates to a battery having an active element of this type as well as a method for producing an active element of this type and a battery of this type. The battery according to the invention is suitable in particular for use in medical implants.

Active element and battery as well as method for the production thereof

Battery-operated device, having an electrically operated functional unit and an electrochemical voltage source, which are housed together in an essentially gas-tight device housing, the electrochemical voltage source having an electrolyte based on an ionic liquid and a coating-free plastic battery housing.

Battery operated device, in particular implantable medical-electronic device

The invention relates, among other things, to an electrode for a lithium battery with an electrode element of a material consisting of or comprising: 

Electrode for a lithium battery and method for producing the same

A battery having a housing assembled from multiple parts, of which one housing part is implemented like a vessel having an initially open front side and the other housing part is a closure part, which closes the vessel-like housing part on its initially open front side, and having at least one first and at least one second electrode, each of which is formed by a planar material, of which the first electrode is electrically connected to an electrically conductive housing part of the battery, while the second electrode is electrically connected to an electrically conductive contact, which is electrically insulated from the remaining housing, the battery comprising a molded part which is provided with at least one first recess for receiving and positioning at least one section of the first electrode or the first electrodes at a time.

Galvanic cell

The invention concerns an electromedical implant for intracardial coronary therapy comprising an implant housing in which functional component parts of the implant, namely a circuit, a battery and the like, are disposed. It is characterized in that the battery () has a flat side (), an underside () and a peripherally extending narrow side () and the battery () is arranged with its underside () on an internal base surface () of the implant housing () and the circuit () is arranged in adjacent relationship with a flat side () of the battery ().
