[0001] The invention relates to the technical field of high-sealing tooling for lead-acid batteries, in particular to a high-sealing tooling for lead-acid batteries and a lead-acid battery thereof. Background Art

[0002] Lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharge state of lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main components of the positive and negative electrodes are both lead sulfate. When charging, the lead-acid battery will produce a small amount of sulfuric acid mist gas, which is also sandwiched with a small amount of lead, as well as hydrogen and oxygen. In the repeated charge and discharge test of lead-acid batteries, the accumulated gas is relatively large, which seriously pollutes the working environment and is not good for the health of the testers.
