A method and device for producing a battery electrode () by: pouring a powder mixture quantity () into a cavity (), laying an electrically conductive diverter () on powder mixture (), pouring a further quantity () of same powder mixture () into same cavity (), and compressing the two powder mixture quantities (). The device has a filling cavity () for powder mixture (), at least one compression means () for compressing powder mixture (), and support () and fixing means () for positioning and fixing an electrically conductive diverter (). The diverter () is situated so that partial quantities () of powder mixture () are located above and below diverter (). The support means () and fixing means () are situated in such a way that a ratio of the partial quantities () of powder mixture () above and below the diverter () remains essentially maintained.

Method and device for producing electrodes for batteries

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-operated implantable medical device comprises a battery, a measuring device for determining the state of charge of the battery through measurement of the no-load voltage, and an electric load. The no-load voltage of the battery has an increased drop in a range in which a remaining residual energy suffices to keep the operation of the device going for a minimum period of time required to carry out a therapeutic process.
