A material, in particular an active material, for an electrode of a galvanic element, and a method for the production of the material, a mixture for the production of an electrode for a galvanic element, and a galvanic element, in particular a battery, and a medical implant comprising such a battery.

Active material for an electrode of a galvanic element

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

A method for manufacturing of a powder mixture for a battery electrode that includes suspending of particles of at least one binder within an inert solvent producing a first suspension, slowly suspending of particles of an active material within the first suspension producing a second suspension, drying of the second suspension producing a granulate material. Further relates to a respective powder mixture, an electrode and a method of manufacturing the electrode.

Powder mixture for manufacture of a battery electrode, a respective battery electrode and a method for manufacturing same

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

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

Bulk-modified potting composition based on a curable epoxy resin or on a mixture of these resins, where the resin or the mixture is composed of an epoxy resin, a hardener, where appropriate an accelerator, and also other additives, such as fillers, flexibilizers, and colorants, which potting composition (a) comprises a three-dimensionally crosslinked polysiloxane in disperse form and with a particle size in the range from 0.02 &#x3bc;m to 50 &#x3bc;m, which, where appropriate, has reactive groups which can react chemically with the epoxy resin and/or the hardener, (b) a selected linear or branched siloxane compound which has reactive groups which can react chemically with the epoxy resin and/or the hardener, and also, where appropriate, (c) a low-molecular-weight oligomeric siloxane compound, the use of the potting composition as an engineering material or as an insulating material, and the moldings and insulation produced therefrom.
