ず、実用化には至っていない。Conventional technology and its problems Primary batteries that use lithium as the negative electrode active material have been put into practical use, with manganese dioxide and carbon fluoride used as the positive electrode, and organic solvents used as the electrolyte. During ~ Lithium, which is the negative electrode active material, grows in a dendritic manner on the negative electrode surface, destroying the separator and causing internal short circuits.
Due to factors such as reaction with organic solvents and passivation by forming an insulating film, only a limited charge/discharge cycle can be obtained, and it has not been put into practical use.

Publication No. 3 describes that a lithium ion conductive protective film is formed by surface treating lithium as a negative electrode active material with ethylene carbonate. Further, JP-A-59-173977 describes that dendritic growth of lithium is suppressed by interposing a polymer layer containing lithium ions at the interface between the negative electrode and the separator.

It has not yet been possible to charge and discharge with a large current. Furthermore, it is known that a lithium-aluminum alloy can be used as a negative electrode to increase capacity, but this has not been put to practical use.

As long as it does not react with the negative electrode active material such as lithium, which has no hydrophilic properties, it will be easily destroyed even if the negative electrode active material grows in a dendritic shape, such as with ethylene or polypropylene nonwoven fabric. There isn't.

スハーメチックシールして密閉するものである。Next, a method for manufacturing this organic electrolyte battery will be explained. After applying an arylacetylene polymer dissolved in a solvent to the surface of the positive electrode 1 formed into a sheet facing the negative electrode 6, the solvent is evaporated, dried, and solidified to form a film-like separator 2. Even if the solvent is not completely removed at this time, it will not become a mold in practical terms. A unit cell 8 is manufactured by placing a negative electrode (B) on this seventh pallet (2), and the conductive film (4) is interposed on the other surface of the battery, and the ends are held between the current collectors (5) and placed in a battery case (9). The terminal 7 is immersed in an electrolytic solution 6 and hermetically sealed with a glass hermetic seal.
こうして製造された有機電解液電池においては、製造時

うる。Furthermore, no short circuit occurs due to this. It goes without saying that the separator 2 thus formed needs to have a certain thickness in order to prevent short circuits between the positive electrode 1 and the negative electrode 5 that would occur due to uncoated coating. Deo
, oosmi or more, it was found that defects due to minute short circuits could be prevented. Further, with such a thickness, electrical resistance is not a problem and the film can function as a separator.

In the unit cell, the volume decreased by 10%.
