The present invention concerns electrode materials capable of redox reactions by electron and alkali-ion exchange with an electrolyte. The applications are in the field of primary (batteries) or secondary electrochemical generators, supercapacitors and light modulating systems of the electrochromic type.

Electrode materials with high surface conductivity

The present invention concerns electrode materials capable of redox reactions by electrons and alkali ions exchange with an electrolyte. The applications are in the field of primary (batteries) or secondary electrochemical generators, super capacitors and light modulating system of the super capacitor type.

A process for extruding a thin positive electrode sheet having at least 40%/wt of solid content for a lithium polymer battery through a single or twin screw extruder is disclosed as well as a positive electrode sheet produced therefrom. A mixture of active cathodic intercalation material, lithium salt and electronic conductive material is mixed with a polymer of the polyether family in a ratio of at least 40% of total weight into the mixing chamber of an extrusion machine and extruded through a classical sheet die into a thin cathode sheet or film onto a substrate in sheet form.

A current collector for polymer electrolyte thin film electrochemical cells and an electrochemical generator is disclosed. The current collector comprises a polymer substrate support film having a thickness of between 1 and 15 microns; a conductive metallic layer having a thickness of less than 3 microns, coated by metal vapor deposition onto at least one surface of the polymer substrate film; and a protective metal or metal oxide layer deposited onto the conductive metallic layer, having a thickness of between 5 and 500 nanometer and being electronically conductive.

In a rechargeable lithium battery including inter alia a lithium anode, a lithium ion reducible cathode bonded with a polymer, as well as a polymer electrolyte, potassium ions are introduced either in the cathode or in the electrolyte, or in both of them at the same time, so that potassium is distributed in the cathode and the electrolyte when the generator has reached equilibrium. This has the effect of stabilizing the performances of the battery during cycling in terms of energy and power.

Polymer electrolyte lithium battery containing a potassium salt

An orthosilicate whose structure is based on SiO.sub.4.sup.4 tetranions which contains at least one transition element with at least two valence states. Lithium ingresses or egresses into or from the structure in order to compensate for a change in valency of the redox couple during electrode operation and thereby maintain overall electroneutrality.
