    摘要： Gas generation of a non-aqueous electrolyte battery having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium as negative electrode is suppressed.A non-aqueous electrolyte battery comprising a non-aqueous electrolyte containing an electrolyte salt and a non-aqueous solvent, a positive electrode and a negative electrode is characterized in that the main active material of said negative electrode is an active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium and the auxiliary active material of said negative electrode is an active material that at least intercalates lithium ions at a potential lower than 1.2 V relative to the potential of lithium and that there exists lithium showing a spin-lattice relaxation time (T1) of not less than 1 second as determined by a solid-state Li—NMR measurement in the main active material of said negative electrode. A method of manufacturing a non-aqueous electrolyte battery containing a non-aqueous electrolyte, a positive electrode and a negative electrode (a main active material and an auxiliary active material of the negative electrode) is characterized in that the negative electrode potential is lowered to not higher than 0.8 V relative to the potential of lithium at least once in the initial cycle.

    摘要： An electrode for a fuel cell of the invention comprises a cation-exchange resin, carbon particles and a catalyst metal which is amorphous. The electrode has high activity, a high catalyst utilization and high CO tolerance and is highly active in the electrochemical oxidation reaction of methanol. Furthermore these qualities of the electrode were extremely improved when the catalyst metal was loaded mainly on sites where the surface of the carbon particles contacts proton-conductive passages in the cation-exchange resin. Consequently, a fuel cell with the electrode of the invention has a high output current and a long life, and can be produced at low cost.

The non-aqueous electrolyte battery comprises a non-aqueous electrolyte containing an electrolytic salt and a non-aqueous solvent, a positive electrode and a negative electrode having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium and is characterized in that a film coat having a carbonate structure and a thickness of not less than 10 nm exists on the surface of said negative electrode and that the non-aqueous electrolyte battery is operated in a region of potential of the negative electrode higher than 0.8 V relative to the potential of lithium. A method of manufacturing a non-aqueous electrolyte battery having a non-aqueous electrolyte, a positive electrode and a negative electrode having a negative active material that intercalates/deintercalates lithium ions at a potential not lower than 1.2 V relative to the potential of lithium is characterized in that a film coat having a carbonate structure is brought into existence on the surface of said negative electrode by lowering the potential of the negative electrode to lower than 0.8 V relative to the potential of lithium at least once in an initial cycle.
