摘要： The present invention concerns a lithium electrochemical generator including at least one composite electrode comprising an active material and a first and second solid electrolytes non-homogeneously distributed into the composite. The first solid electrolyte is of mineral nature, vitreous or partly vitreous, and is a specific conductor of lithium ions, and is preferably localized on the surface of the particles of active materials of the electrode. The second solid electrolyte is organic, comprises a dry or gelified polymer electrolyte conducting ions surrounding the dispersed solid phases and acts as a deformable binder, preferably elastomeritically, of the composite in contact also with the collector and the separator electrolyte of the generator. A thin layer of the first electrolyte wets and coats at least a part of the surface of the active material particles to protect the coated surface of passivation or degradation reactions induced by the second electrolyte, and to maintain a good quality of ionic and electronic exchanges between the active material of the electrode and the other components of the composite, the first electrolyte being impermeable to the components of the second electrolyte.

摘要： 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.

摘要： The catalyst-coated membrane has a proton exchange membrane with two opposite sides, and a catalyst coating applied directly to one of the two sides, the catalyst coating having a plurality of openings defined therethrough and scattered thereacross, the openings defining passages to the proton exchange membrane in which corresponding electro-chemical active surfaces of the catalyst coating are exposed. The openings can be defined in the catalyst coating after application thereof or during application thereof.
