Problems solved by technology

[0004] The existing coating material is mainly made of metal lead and the auxiliary material of the coating material, which makes the battery have a great impact on the environment during use. Material accumulation, precipitation and delamination are easy to occur in the medium, which greatly affects the electrical conductivity of the coating material
At the same time, during the use of the battery, hydrogen and oxygen will be generated, and the generated gas will also accumulate in a large amount inside the coating material, thereby reducing the contact area between the conductive material and sulfuric acid, which is not conducive to the repeated use of the battery and causes the charging effect of the battery worse and worse

Abstract

The invention relates to the technical field of storage battery manufacture, and concretely relates to a preparation method of an alloy coating material. The preparation method comprises the followingsteps: a step 1: a proper amount of zinc powder and polypheylene ether amide are taken, water is added with uniform stirring, in order to obtain mixed colloid; a step 2: a tube shaped first die and atube shaped second die are taken, the first die is disposed on the second die, the mixed colloid is injected into the step 1, and drying is carried out in order to obtain a first housing with elasticity and a second housing with elasticity; a step 3: the mixed colloid in the step 1 is taken and dried in order to form an opening at one end of the film sealed first housing, mixed colloid in the step 1 is injected in the first housing, the film is employed for sealing an opening at the other end of the first housing, in order to obtain the first coating material; a step 4: the film in the step 3is used for sealing an opening at one end of the second housing, mixed colloid in the step 1 is injected in the second housing, the film in the step 3 is employed for sealing an opening at the otherend of the second housing, in order to obtain the second coating material. The alloy coating material with good conductivity is prepared.

Description

technical field [0001] The invention relates to the technical field of storage battery manufacturing, in particular to a method for preparing an alloy cladding material. Background technique [0002] A battery is a device that can convert chemical energy into electrical energy. After discharge, it can regenerate the internal active materials by charging, store electrical energy as chemical energy, and convert chemical energy into electrical energy again when it needs to be discharged. This type of battery is called It is a storage battery, also known as a secondary battery. Most of the storage batteries used in the equipment of existing automobiles and battery cars are lead storage batteries. [0003] Lead-acid batteries include positive and negative plates, both of which are composed of grid plates and active materials filled on the grid plates, and the battery is charged and discharged through the reaction of the electrolyte and the active materials. Wherein, the grid pla...
