Description

technical field [0001] The invention relates to a lead-acid storage battery with a plate type pole plate, which belongs to the field of power storage batteries. Background technique [0002] The production process of plate-type lead-acid batteries is relatively simple: because the plate coating machine is used for fast coating, less pollution, and easy processing, and the plates can be made very thin, so that the instantaneous discharge of the battery is large. Therefore, plate-type lead-acid batteries are the first choice for automobile starting batteries, and are also the most widely used battery production method in the production of spare valve-regulated batteries. [0003] However, in the production of electric vehicles, due to the special requirements of electric vehicles on the power supply, such as: long-term rate, long life, and large capacity, currently all manufacturers basically use tubular plate lead-acid batteries. The feature of the tubular plate lead-acid ba...
