　　Development history of lead-acid battery technology in China

　　The reform of lead-acid battery separators and negative electrode additives caused by rubber separators replacing wooden separators in the mid-to-late 1950s; the structural reform of lead-acid batteries caused by plastic tanks and internal connections in the early 1970s; the reform of lead-acid battery structures in the 1980s The reform of lead-acid battery manufacturing equipment and manufacturing technology caused by the "industry introduction" in the mid-to-late 1990s (automatic plate casting machine, automatic paste mixing machine, intelligent curing room, automatic assembly line and maintenance-free battery technology, mesh technology, etc.; In the early 1990s, the birth of valve-regulated sealed lead-acid batteries led to the reform of battery structure (valve-regulated sealed, colloid); in the late 1990s, the deep-cycle power lead-based battery was triggered by electric bicycle batteries in Changxing, Zhejiang. The development of China's lead-acid battery industry has gone through five important periods of technological development, including the innovation of acid battery manufacturing technology, as well as the continuous introduction, digestion, absorption and influence of advanced industrial countries such as Europe, the United States, Japan and South Korea in China. The impact of investment and factory building. At present, the technical level of China's lead-acid battery products has generally been close to the product level of international advanced industrial countries: the United States, Japan, Germany, Italy, the United Kingdom, Australia and other countries; among them, China's independent innovative product - electric bicycle battery The deep-cycle power battery manufacturing technology represented by the company has surpassed the technology of advanced industrial countries such as Europe, the United States, Japan and South Korea in some aspects, and is at the leading international level. At present, China has become the world's lead-acid battery production base.
