Problems solved by technology

[0010] The disadvantage of the third preparation method is that the strength of the gel-like polymer film or layer is reduced by electrolyte impregnation and it needs to be handled, making it difficult to prepare batteries
Moreover, since there is no separator between the positive and negative electrodes, the battery is prone to internal short circuits

Embodiment 1-10

[0038] The prepared nonaqueous electrolyte battery, which includes an elliptical wound power generating element composed of a positive electrode, a separator, and a negative electrode, was housed in a metal-laminated resin film case with a nonaqueous electrolyte (not shown). The metal laminated resin film case can be produced by thermally welding the metal laminated resin films.

[0039] The appearance of the non-aqueous electrolyte battery of embodiment 1-10 is shown in figure 2 middle. exist figure 2 Among them, reference numeral 11 denotes a power generating element, reference numeral 12 denotes a battery case, reference numeral 13 denotes a thermally welded part of the battery case, reference numeral 14 denotes a positive terminal, and reference numeral 15 denotes a negative terminal.

[0040] The positive electrode can be prepared as follows: mix 90% by weight of lithium-cobalt composite oxide as the positive electrode active material, 6% by weight of PVDF as the bind...

Embodiment 11

[0050] In Example 11, except that the pressing process is not implemented during the heating of the heating and cooling steps but only during the cooling of the heating and cooling steps and the pressure is 0.1 MPa / cm 2 A non-aqueous electrolyte battery having the same composition as in Example 1-10 was prepared in the same manner as in Example 1-10 except that it was carried out under the same conditions. The battery is referred to as "A11".

Embodiment 12

[0052] In Example 12, except that the pressing process is not carried out during the cooling process of the heating and cooling step but only during the heating process of the heating and cooling step and the pressure is 0.1 MPa / cm 2 A non-aqueous electrolyte battery having the same composition as in Example 1-10 was prepared in the same manner as in Example 1-10 except that it was carried out under the same conditions. The battery is referred to as "A12". Comparative Example 1

Abstract

A process for the production of a non-aqueous electrolyte battery which comprises a polymer layer forming step of forming a polymer layer on one side of at least one of a positive electrode, a negative electrode and a separator and an electricity-generating element preparing step of laminating or winding the positive electrode, the negative electrode and the separator to prepare an electricity-generating element. The process for the production of a non-aqueous electrolyte battery further comprises battery preparing step of receiving the electricity-generating element in a battery case, injecting an electrolyte into the battery case and then hermetically sealing the battery case to prepare a non-aqueous electrolyte battery and a heating and cooling step of heating and cooling the non-aqueous electrolyte battery while the battery case is under pressure.

Description

field of invention [0001] The present invention relates to methods for preparing nonaqueous electrolyte batteries such as polymer batteries. Background of the invention [0002] A polymer battery is a non-aqueous electrolyte battery comprising a positive electrode and a negative electrode integrally bonded to each other having a polymer layer impregnated with an electrolyte, optionally with a separator therebetween. Conventional methods for preparing polymer batteries are described below. [0003] Referring to the first preparation method of a polymer battery, the polymer material is dissolved in a solvent. This solution is then applied to the surface of the positive electrode, negative electrode or separator. The positive electrode and the negative electrode are stacked with a separator disposed therebetween, and are selectively wound to prepare a power generating element. Subsequently, the power generating element was dried to evaporate the solvent to form a polymer lay...
