Abstract

The invention discloses a high-capacity long-life battery, and relates to the technical field of storage battery material preparation. The battery is prepared from, by mass, 1000 parts of lead powder,2-3 parts of SnSO4, 3-4 parts of Sb2O3, 1-1.2 parts of polyester fibers and 2-3 parts of 4BS, the seed crystal size of the 4BS is 5-15 micrometers, the length of the polyester fibers is 3-5 mm, and the breaking strength is larger than or equal to 6.5 g/dtex. Through the reasonable matching of the components, the initial capacity of the battery is high, and the structural strength of the battery is high; meanwhile, the preparation process of a positive plate is stable in process, and the content of tetrabasic lead sulfate in positive plate lead plaster and the stability of crystal size are ensured; the content of the tetrabasic lead sulfate in the prepared positive plate lead paste is high (can reach 80% or above), crystalline particles are small, the granularity is uniform, the charging formation efficiency of a storage battery is high, the initial capacity is large, the service life is long, and the consistency of the storage battery is good.

Description

technical field [0001] The invention belongs to the technical field of storage battery material preparation, in particular to a high-capacity and long-life battery. Background technique [0002] The battery is mainly composed of a battery tank, a positive plate, a negative plate, a separator and an electrolyte. Under normal circumstances, there is a certain contradictory relationship between the capacity of lead-acid batteries and battery life. A battery with a high initial capacity will tend to soften at the end of its life, reducing battery life; while a battery with high structural strength will have a longer battery life, but its initial capacity is lower. [0003] Utilizing pressure to promote the diffusion of the electrolyte and reducing the thickness of the plate or the density of the lead paste can improve the utilization rate of the positive active material. However, these methods reduce the service life of the pole plate, increase the corrosion of the grid, and p...
