The battery itself will not pollute the environment

When it comes to batteries (lead-acid batteries), people often talk about its environmental pollution problems and rashly conclude that it should not be developed. In fact, the lead-acid battery is the highest recovery rate of all the batteries. It is not discarded like other lithium batteries and thrown everywhere, polluting the environment.


In general, contamination of lead-acid batteries can occur in three stages.


The first is the mining and smelting of lead ore. This mainly occurs in small factories and mines produced using the “Tufa”. If we can overcome local protectionism, it is possible to technically eliminate this part of the pollution by renovating or shutting down small factories and mines within a limited time.


The second is the production of lead-acid batteries. Some large companies have done a good job in the environmental protection and safety of the manufacturing process, and the company has won the title of “National Environmentally Friendly Enterprise”, which indicates that the pollution of lead-acid batteries in the production process can be managed. Of course, there are still a number of lead-acid battery companies that still need to strengthen pollution control. To solve the pollution control problem at this stage, firstly, the relevant departments are required to issue strict production licenses. For heavily polluting production plants, they should be rectified within a time limit. Those who fail to meet the standards should be responsible for canceling the production license. It is worth mentioning that there are some enterprises that have relocated factories without pollution control. The government should strictly stop such behavior.


The third is the recycling of waste lead-acid batteries. Nowadays, dry regeneration technology is often used in the regeneration of lead-acid batteries. The disadvantage is that the recovery rate of lead is not high, and the energy consumption is not low. It should be upgraded. In addition, the manual “recycling workshop” for the recycling of lead-acid batteries should be resolutely banned. At present, China has mature new technologies for recycling used batteries, which can reduce electricity consumption to less than 350 kWh/ton and recovery rate of 98.5%. This new technology should accelerate the industrialization and promote the pollution of lead-acid battery regeneration drop to lowest.


In summary, there is indeed a pollution problem in the current lead-acid battery production chain in China, but this problem is not caused by the so-called “old” and “backward” of lead-acid batteries. It is a management problem that can be solved through hard work. . As long as the relevant departments and local governments earnestly take responsibility and manage effectively, they will be able to do the lead pollution control work as well as Europe and the United States. Therefore, we cannot abandon the use of lead-acid batteries because of squandering food, and no longer support its development.


However, the status quo is that in China, the research and development of lead-acid batteries is not supported by the government. A large number of scientific and technological personnel have to change their research direction. Large enterprises have to spend large sums of money to purchase foreign technology and equipment. Small enterprises have been involved in unfair competition due to low cost. Environmental pollution; coupled with poor management, formed an industrial pattern in which advanced technology and backward technology coexisted, both disrupting the market and ruining the reputation of lead-acid batteries.


At present, lead-acid battery technology continues to develop, and its specific power and specific energy can continue to increase. In particular, extending the life is not only conducive to saving energy, saving materials, reducing the cost of electricity storage more effectively, but also reducing the workload of battery regeneration and directly reducing lead pollution. Foreign lead-acid batteries can achieve 6,000 cycles. We should also work hard in this regard to make a battery top ten, so that lead-acid batteries can make greater contributions to China's economic and social development.
