Lithium secondary battery

A manufacturing method for an electrode in which ultra fine particles of active material formed in gas by an evaporation method are carried in a gas flow and blown onto a surface of a substrate, so that an electrode comprising a thin film of active material is formed on the surface of the substrate. A manufacturing method for an electrode-electrolyte composite in which ultra fine particles of active material formed in gas by the evaporation method are carried in a gas flow and blown onto a surface of a film comprising a solid electrolyte, so that an electrode comprising a thin film of active material is formed on the surface of the film. The above manufacturing method for an electrode can provide an anode or a cathode comprising an ultra thin film having an uniform thickness of under 10 microns inclusive, for example. The above manufacturing method for an electrode-electrolyte composite can provide, with good productivity, an electrode-electrolyte composite in which an adhesion of the electrode with the electrolyte is excellent and the electrode is of an ultra thin type having an uniform thickness.

Manufacturing method for electrode

A polymer solid electrolyte comprises a crosslinked polyester in which a salt is dissolved, and which has a crosslinked structure of the formula: ##STR1## where R stands for an inert group other than a hydrogen atom. It is suitable as an electrolyte and a separator for a battery, especially a lithium battery which can be recharged. Batteries including such electrolyte are also disclosed.
