Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an organic electrolyte battery comprising a positive electrode, a polymer electrolyte layer made of a polymer capable of absorbing and retaining an organic electrolyte, and a negative electrode.

[0002]

2. Description of the Related Art In response to the recent trend toward smaller, lighter, and thinner portable devices, lithium-ion secondary batteries have become smaller and smaller.
Light weight and thinness are strongly demanded. Lithium-ion rechargeable batteries have been put to practical use, and have greatly contributed to the reduction in size and weight of mobile phones and notebook computers.
The demand for thinner is increasing. However, in a conventional lithium ion secondary battery that tightly binds the electrodes and the separator with a strong outer case and minimizes the distance between the electrode plates and achieves good contact between the electrode separators, the strength of the outer case is maintained. Thickness is necessary, and there is a limit to thinning.

As one method of pursuing a reduction in thickness, a lithium polymer secondary battery using a porous polymer that absorbs and retains an organic electrolyte in an electrolyte layer serving as a separator has been receiving attention. Above all, in a battery system in which the same polymer is joined and integrated into the electrolyte layer and the electrode, good contact between the electrolyte layer and the electrode can be realized without using a strong outer case as described above. It is effective for thinning. US Pat. No. 4,830,939 and US Pat. No. 5,47,939 disclose an example in which an electrolyte layer and an electrode are joined and integrated.
8,668.

In the case of US Pat. No. 4,830,939, a mixed solution of a monomer and an electrolytic solution is applied on lithium metal or a positive electrode of a negative electrode, and then the monomer is polymerized by ultraviolet rays or an electron beam to form a solid polymer electrolyte. doing. In this case, since the electrolyte layer is formed along the minute irregularities on the surface of the electrode plate, a good contact between the electrode and the electrolyte layer can be realized without applying any binding.

In the case of US Pat. No. 5,478,668, a copolymer of vinylidene fluoride (VDF) and propylene hexafluoride (HFP) (P (VDF
-HFP)), a positive electrode, a negative electrode of a laminated electrode, and an electrolyte layer serving as a separator are manufactured, and then the separator and the positive electrode or the negative electrode are integrated by heat fusion.

[0006] By bonding and integrating the electrode and the electrolyte layer as in the above two examples, a thin battery that can be discharged even when a flexible and thin laminate sheet outer casing is used can be obtained.

[0007]

However, in order to obtain a practical battery capacity, simply stacking the above-mentioned laminated electrode in which the positive electrode, the electrolyte layer, and the negative electrode are integrated and integrated, as compared with a lithium ion secondary battery, There is a problem that the ratio of the body to the battery weight increases. In a general lithium ion secondary battery, as shown in FIG. 5, a positive electrode 6 in which a positive electrode mixture layer 6b is formed on both surfaces of an aluminum foil 6a as a positive electrode current collector, and both surfaces of a copper foil 7a as a negative electrode current collector A negative electrode 7 having a negative electrode mixture layer 7b formed thereon is opposed to each other with a separator 8 interposed therebetween, and is wound. For this reason, in the lithium ion secondary battery, a pair of battery configurations is formed on both sides of the positive electrode current collector 6a and the negative electrode current collector 7a, and the current collector is used efficiently. On the other hand, in the lithium polymer secondary battery in which the electrolyte layer and the electrode are joined and integrated as shown in the conventional example, it is extremely difficult to apply electron beams, ultraviolet rays, or heat uniformly over many layers. Therefore, the requirement of this joining becomes an obstacle, and a configuration of positive electrode-separator-negative electrode-positive electrode like a lithium ion secondary battery cannot be adopted. Therefore, in the conventional lithium polymer secondary battery, as shown in FIG. 4, a positive electrode 1 in which a positive electrode mixture layer 1b is formed on one surface of a positive electrode current collector 1a, and a negative electrode mixture layer The negative electrode 2 on which the electrodes 2b are formed is opposed to each other with the electrolyte layer interposed therebetween, and one battery configuration is formed by a set of a positive electrode current collector and a negative electrode current collector. Therefore, the current collector on the side where the electrode mixture is not applied is not used.

[0008] Lightweight aluminum or the like can be used as the material of the positive electrode current collector. However, aluminum cannot be used as the negative electrode current collector, and the current collector becomes heavy because copper or the like is used. In addition, there is a disadvantage that the weight efficiency of the negative electrode current collector with respect to the battery weight is poor.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide an organic electrolyte battery having a structure in which the battery weight is reduced while maintaining good battery characteristics.

[0010]

In order to achieve the above object, the present invention has a negative electrode in which a negative electrode mixture layer is formed on both surfaces of a negative electrode current collector, and both surfaces of which are sandwiched between positive electrodes via a polymer electrolyte layer. It is characterized by having an electrode structure.

In particular, the present invention relates to a negative electrode having a sheet or film-shaped negative electrode mixture layer mainly containing spherical carbon particles containing a polymer absorbing and retaining an organic electrolyte on both surfaces of a porous current collector; A lithium-cobalt composite oxide-based sheet or film-type positive electrode mixture containing a polymer that absorbs and retains the organic electrolyte through a porous film-like polymer electrolyte layer made of a polymer that absorbs and retains the organic electrolyte on both surfaces An organic electrolyte battery in which a positive electrode having a layer formed thereon is opposed to each other, and the whole is laminated and integrated in a sheet or film shape, and an organic electrolyte solution is absorbed and held therein.

According to the present invention, it is possible to reduce the thickness and weight of the battery while maintaining good battery characteristics.

[0013]

In addition, the reaction area can be doubled by setting the opposing surfaces of the positive electrode and the negative electrode to two surfaces with respect to one negative electrode current collector, so that the load per unit area can be reduced, and Charge and discharge can be performed.

In particular, when adopting a configuration in which the laminated electrodes are laminated in multiple layers, it is preferable to use a perforated plate such as a perforated plate.

[0017] Further, by making the surface dimensions of the reaction part of the positive electrode and the negative electrode the same, no extra electrode area is required.

Further, by making the surface dimension of the reaction part of the negative electrode larger than that of the reaction part of the positive electrode, a short circuit at the electrode end can be prevented.
