摘要： The invention relates to a composite electrode material consisting of a carbon coated complex oxide, fibrous carbon and a binder. Said material is prepared by a method which comprises co-grinding an active electrode material and fibrous carbon, and adding a binder to the co-grinded mixture to lower the viscosity of the mixture. The fibrous carbon is preferably vapor grown carbon fibers.

摘要： Process for preparing a ceramic from an inorganic base material that is in the form of a powder having a high melting point, comprising a step of mixing the powder of the inorganic base material with a second inorganic component also in powder form and which acts as a dopant for the inorganic base material. The dopant is constituted by a single inorganic material or by a mixture of at least two inorganic materials having a dopant effect on the inorganic base material. The process comprises a sintering step carried out at a high temperature. The ceramics obtained, because of their high density, are advantageously used as a target element. Films and electrodes obtained from these ceramics exhibit particularly advantageous properties.

摘要： An electrochemical generator comprising thin films including a positive electrode and its collector, and a sheet of a host metal intended to later on constitute a negative electrode, as well as an electrolyte which is conductive towards alkaline ions and also a source of alkali ions. The sheet of the host metal has voids whose quantity and arrangement are capable of locally absorbing any lateral expansion of the sheet of host metal and thereby substantially preventing all cumulative change in the plane of the sheet of host metal when there is an initial formation of alloy in the sheet between the host metal and an alkali metal which is brought about by the alkaline ions. A method of manufacturing such a generator is also described.

摘要： A positive electrode material, having particles having a complex oxide OC1 core, an at least partial complex oxide OC2 coating, and an adhesive carbon surface deposit. The material is characterized in that the complex oxide OC1 is an oxide having a high energy density and in that the oxide OC2 is an oxide of a metal having a catalytic effect on the reaction of the carbon deposit, the oxide having good electronic conductivity. The presence of the OC2 layer facilitates the deposit of a carbon adhesive layer at the surface of the oxide particles, and improves the conductivity of the material when the latter is used as an electrode material. The electrode material can particularly be used in the manufacture of a lithium battery.
