Description

technical field

[0001] The invention relates to the field of lead-acid batteries, in particular to a lead-acid battery. Background technique

[0002] Traffic exhaust emissions and the burning of fossil fuels have had an impact on the climate that cannot be underestimated. With the depletion of oil and other resources, human beings are facing two urgent problems of environmental protection and rational use of resources. They attach great importance to and vigorously develop new batteries powered by Energy, moving closer to the era of electric vehicles, the development of zero-emission, pollution-free, and noise-free electric vehicles has broad application prospects.

[0003] The core of an electric vehicle is a power source, and lead-acid batteries are currently the most widely used storage batteries. However, due to the limitations of the electrochemical system of the lead-acid battery, the mass density and power density of the battery are relatively low; when used as a pow...
