Problems solved by technology

[0003] Traditional lead-acid batteries have the following disadvantages: 1. Traditional lead-acid batteries often have acid overflow, acid seepage and gas acid mist escape during use, which not only corrodes equipment, but also pollutes the air, which is extremely harmful to the urban environment; 2. The liquid electrolyte in traditional lead-acid batteries is easy to corrode and wash away the plates, resulting in early damage to the plates and the shedding of the active material PbO2 in the plate layer, causing internal short circuits in th

Description

technical field [0001] The invention relates to a battery, in particular to a nano-composite bipolar storage battery and a preparation process for a bipolar plate base. Background technique [0002] Batteries are divided into primary batteries and secondary batteries, wherein secondary batteries refer to batteries that can be repeatedly charged and discharged. The earliest and most widely used secondary battery is the lead-acid battery, which can be manufactured using unipolar or bipolar, or a quasi-bipolar battery that is used alternately between unipolar and bipolar. [0003] Traditional lead-acid batteries have the following disadvantages: 1. Traditional lead-acid batteries often have acid overflow, acid seepage and gas acid mist escape during use, which not only corrodes equipment, but also pollutes the air, which is extremely harmful to the urban environment; 2. The liquid electrolyte in traditional lead-acid batteries is easy to corrode and wash away the plates, resul...
