AI Technical Summary
Existing lead-acid batteries have low sealing reaction efficiency, leading to water loss, capacity loss, and bulging. Furthermore, the active material is prone to detachment, affecting the battery's lifespan.
A fiber bag made of nanofiber mesh is wrapped around the surface of the positive and negative electrode plates and separated by an AGM separator. The microporous gas channels of the nanofiber mesh allow oxygen and hydrogen to recombine into water in a timely manner, improving the sealing reaction efficiency and preventing the active material from falling off.
It improves the sealing reaction efficiency of the battery, reduces the risk of water loss and bulging, and extends the battery's lifespan.

[0002] The internal structure of the existing lead-acid battery mainly consists of positive plates, negative plates, electrolyte, AGM separators, and pole posts. The positive and negative plates are isolated by wrapping with AGM separators. The battery gas combination mode is adsorption type, which uses the gap of the separator as a gas channel to combine the oxygen generated by the positive plate with the hydrogen generated by the negative plate into water. The gap gas channel of the separator has certain limitations, so that part of the oxygen generated by the positive plate cannot be completely combined with the hydrogen of the negative plate in time, but is discharged to the outside of the battery through the safety valve. The sealing reaction efficiency of the battery is low, which easily causes the battery to lose water, lose capacity, and bulge. The active material falls off in the later use of the battery, affecting the service life of the battery. SUMMARY
