Disclosed is a flat organic electrolyte battery capable of stably discharging in an extremely low temperature environment without deteriorating characteristics of conventional graphite fluoride lithium batteries. Specifically disclosed is a flat organic electrolyte battery comprising a negative electrode, a positive electrode, an organic electrolyte solution, a separator, a top plate, a positive electrode case and a gasket. The negative electrode contains either metal lithium or a lithium alloy as a negative electrode active material. The positive electrode contains 100 parts by weight of graphite fluoride as a positive electrode active material and 15-30 parts by weight of a conductive agent. The separator is interposed between the negative electrode and the positive electrode. The top plate is in contact with the negative electrode and also serves as a negative electrode terminal. The positive electrode case is in contact with the positive electrode and also serves as a positive electrode terminal. The gasket is interposed between the positive electrode case and the top plate.
Abstract:
The invention provides an apparatus and method for producing multilayer laminates of polymeric electrolyte material incorporating one of more electrode layers. The apparatus (40) comprises an extrusion apparatus (42) for extruding a polymeric material (76) and a pair of heated rollers (46, 48) between which the material (76) and electrodes (60, 68, 72) are pressed in order to produce a continuous extrudate (80). The method may also include producing a gellable mixture comprising a crystallisable polymer and an aprotic organic liquid, forming the mixture as an elongate tape and contacting the tape with an electrode material. A compression and heating step may be present.

The present invention relates generally to highly conductive alkali-metal ion non-crystalline electrolyte systems, and more particularly to novel and unique molten (liquid), rubbery, and solid electrolyte systems which are especially well suited for use with high current density electrolytic cells such as primary and secondary batteries.
Abstract:
A bulk ionically conductive polymer gel is prepared by dissolving a salt such as lithium trifluoromethanesulphonate (which would provide lithium ion conductors) in an organic compound such as N-formylpiperidine. The organic compound dissolves the salt at 20 DEG C but is not a solvent at 20 DEG C (though it is at 215 DEG C) for polyethylene terephthalate. The last-named is a crystallisable polymer which is added in a minor amount at a high temperature to the other components and provides the required mechanical rigidity for the product at lower temperatures.
Abstract:
An organic electrolytic battery provided with a negative electrode (2) made of an alkali metal or an alkali metal compound, a positive electrode (1) and an electrolytic solution (4) prepared by dissolving an electrolyte in an organic solvent, wherein the electrolyte comprises an organic metallic salt wherein a fluoroalkyl group having four or more skeletal carbon atoms is covalently bonded to an anionic group and the anionic group is ionically bonded to an alkali metal ion or alkaline earth metal ion. This battery is prevented from generating heat abnormally and its safety in overdischarge is improved.
