Abstract

The invention relates to the field of storage batteries, and discloses a lead storage battery, the lead storage battery comprises a shell, series connection assemblies and monomer stage groups, a plurality of monomer stage groups are arranged in parallel in the shell along the horizontal direction, and a plurality of series connection assemblies are arranged on two sides of the monomer stage groups in a staggered manner along the arrangement direction of the monomer stage groups and are used for connecting the plurality of monomer stage groups in series; and the monomer stage groups located at the two ends are connected with output and input terminal assemblies. The lead storage battery is different from a traditional lead storage battery in structure, a plurality of series-connection assemblies are arranged on the two sides of single-body stage groups in a staggered mode and used for connecting the single-body stage groups in series to form a series-connection structure of the single-body stage groups, a transversely-placed structure is formed, and the mode that a traditional vertical type top end outlet tab is connected with a busbar is changed into the mode that the traditional vertical type top end outlet tab and the busbar are transversely place and extend out of the two sides in an opposite mode. According to the structure, the utilization rate of active substances in the monomer grade group is not layered in the service life process, and the current distribution uniformity is high.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to a lead accumulator. Background technique [0002] In April 2019, the "Industrial Structure Adjustment Guidance Catalog (2019)" issued by the National Development and Reform Commission clearly stipulates in the 16th sub-item (page 45) of the 19th major item of light industry in the first category of encouragement: New structural sealed lead Acid storage battery belongs to the industry technology that encourages development. [0003] At present, 90% of urban electric transportation vehicles such as express electric vehicles use lead-acid batteries produced by traditional techniques. There is a situation that the service life is only about 300 times, the specific energy is about 35Wh / Kg, and the charging time is more than 6 hours, which is far from the user's expectations. [0004] According to the "2020-2050 China Express Industry Market Prospect and Future Investment Strategy Analysi...
