Description

【Technical field】 [0001] The invention relates to the technical field of lead-acid batteries, in particular to a production process of a low-dimensional nano lead-carbon super battery. 【Background technique】 [0002] Lead-acid battery is not only a traditional industry in my country, but also an important part of the new energy industry. It occupies a dominant position in the battery market and has a wide range of applications and a very important role. According to incomplete statistics, lead-acid batteries consume about 82% of the world's total lead consumption. And in the future, lead-acid batteries will play an indispensable role in applications such as energy storage, starting, power, and backup power. [0003] However, the phenomenon of high investment and high emission has always existed in the production process of my country's lead industry, which consumes a lot of energy and causes great pollution to the atmosphere and water. Not only that, the current lead-acid ...
