preparation example Construction

[0028] The preparation of an SLI parking air-conditioning battery of the present invention is the same as the polar plate formula and assembly process of a conventional lead-acid starting battery. The positive electrode paste of the battery plate in the pole group is made of the following raw material formula in parts by mass: 70-90 parts of lead powder, 0.05-0.15 parts of antimony trioxide, 0.05-0.12 parts of fiber, 0.6-1.5 parts of 4BS, red lead 9-15 parts, 0.02-0.06 parts of sodium additive, 4-8 parts of sulfuric acid and 6-12 parts of pure water. The electrolyte solution used in the chemical conversion contains the following components in mass ratio: dilute sulfuric acid accounts for 90-97%, gas phase SiO 2 Solution 3-10%. Vapor SiO 2 Solution gas phase SiO 2 The mass accounts for 0.1-0.25% of the total composition content of the solution. The density of dilute sulfuric acid in the electrolyte is 1.19-1.3g / cm 3 , the iron content in dilute sulfuric acid is not more th...

Abstract

The invention belongs to the technical field of lead storage batteries, and particularly discloses a preparation method of an SLI parking air-conditioning battery. The method comprises the following procedures: assembling a plate group into a tank, and performing capping, adding electrolyte and forming, wherein the battery plate positive lead paste in the plate group is prepared from the following raw materials in parts by mass: 70 to 90 parts of lead powder, 0.05 to 0.15 part of antimony trioxide, 0.05 to 0.12 part of fiber, 0.6 to 1.5 parts of 4BS, 9 to 15 parts of red lead, 0.02 to 0.06 part of sodium additive, 4 to 8 parts of sulfuric acid and 6 to 12 parts of pure water; carrying out the pole group encapsulation matching by adopting a PE partition plate and glass fiber composite encapsulation assembly process, wherein an electrolyte used for formation comprises the following components in percentage by mass: 90-97% of dilute sulphuric acid and 3-10% of a fumed silica solution. By adding a certain proportion of SiO2 solution, the sulfuric acid layering in the electrolyte can be effectively reduced, and the charging acceptance of the battery is improved, so the deep discharge cycle life of the flooded storage battery is prolonged, and the argillization failure of a positive active material is delayed.

Description

technical field [0001] The invention belongs to the technical field of lead storage batteries, and in particular relates to a preparation method of an SLI parking air-conditioning battery. Background technique [0002] With the development of the logistics industry, the use of commercial vehicles has been converted to home life, and the functional requirements for batteries are becoming stronger and stronger. The functions of conventional flooded start-up batteries can no longer meet the increasing functional requirements of customers, and need to meet more customer needs within a limited cost. [0003] The characteristics of the customer's use are to use the battery to store electricity and continuously supply power to additional electrical equipment such as car refrigerators, air conditioners, and electric blankets. This requires conventional starting batteries to have strong deep discharge cycle capabilities. [0004] Through research and industry information inquiries, ...
