Abstract

The invention relates to the field of battery production, and discloses a solid electrolyte used for horizontal battery production. The solid electrolyte comprises the following components in parts bymass: 80 to 91 parts of a polyhenylene high-molecular organic polymer, 9 to 16 parts of a lithium salt and 1.5 to 4 parts of graphite powder. The graphite powder in the scheme has high electrical conductivity, abrasion resistance and lubricating property, the electrical conductivity of the solid electrolyte can be improved, and then the electrical conductivity of each part of the solid electrolyte is relatively balanced, so that the electrical conductivity is promoted. Through the scheme, the space structure is adjusted by selecting appropriate lithium salt, and through the combined action ofthe polyhenylene high-molecular organic polymer and the lithium salt, the electrical conductivity activation energy is reduced, so that an ion channel of a one-dimensional structure is realized, theleakage probability of the solid electrolyte is reduced, and guarantee is provided for the electrical conductivity of the solid electrolyte.

Description

Technical field [0001] The invention belongs to the field of battery manufacturing. Background technique [0002] In traditional lead-acid batteries, the plates are assembled perpendicular to the ground, and when in use, they are also installed perpendicular to the ground. The plate lugs of the positive and negative plates are placed on the upper part of the battery, and the conductive component busbars and end poles are connected from above. Lead out. [0003] The grid of the horizontal lead-acid battery pole plate is woven with glass fiber and lead composite material, and the pole plate is a quasi-bipolar structure, that is, half of the grid is coated with a positive electrode active material, and the other half is coated with a negative electrode active material It is the negative plate, in which the positive electrode active material and the negative electrode active material are solid electrolytes. After laminating, pickling acid, surface drying, curing and other processes, ...
