In recent days, several articles from the Ministry of Industry and Information Technology have once again stirred up a storm in the battery industry. These articles largely share a common theme: the recycling and reuse of batteries for new energy vehicles. Furthermore, the new national standards for the lithium battery industry, namely the "Lithium-ion Battery Industry Standard Conditions (2018 Edition)" and the "Interim Measures for the Management of Lithium-ion Battery Industry Standard Announcements (2018 Edition)," came into effect on February 15th of this year. This demonstrates the government's active support for the development of lithium batteries.
The Ministry of Industry and Information Technology's intention in doing this is very clear: to guide the replacement of lead-acid batteries with lithium batteries. This would be of great significance both for industrial upgrading and environmental protection. So, how likely is it that lithium batteries will replace lead-acid batteries? And how long will it take to achieve this?
1. Lithium batteries have great development potential, while lead-acid batteries are approaching their physical limits.
Currently, thanks to the efforts of engineers, lead-acid batteries are nearing the limits of their physical properties. Batteries on the market generally need to be replaced every 1-1.5 years, with a maximum lifespan of no more than 3 years. Lithium-ion batteries, on the other hand, are a relatively new technology, having developed for only about fifty years. They already boast a lifespan of over 6 years, high energy density (460-600 Wh/kg), approximately 6-7 times that of lead-acid batteries, and other unparalleled advantages, making their potential limitless.
2. Lead-acid batteries cause serious pollution, while lithium batteries are green and environmentally friendly.
Pollution is currently the biggest challenge facing lead-acid batteries. Lead-acid batteries use lead as the electrode material, and lead itself is a heavy metal pollutant that is harmful to both human health and the environment. Therefore, the production and recycling of lead-acid batteries has always been a bottleneck restricting their sustainable development. In contrast, lithium batteries are green and environmentally friendly. Whether in production, use, or disposal, they do not contain or produce any toxic or harmful heavy metal elements and substances such as lead, mercury, and cadmium, which is very much in line with my country's current environmental protection situation.
Currently, Tianneng and Chaowei, two traditional battery giants, are investing heavily in lithium battery projects and have begun developing lithium battery products. In recent years, domestic lithium battery companies such as CATL and BYD have been listed on the stock exchange. Overseas, traditional lithium battery giants such as Samsung and Tesla have made great efforts to break through lithium battery technology with the promotion of new energy vehicles, which has led to a decrease in the cost of lithium battery products.
The lithium battery market is poised for explosive growth in the future. In addition, lead-acid batteries have already reached their physical limits, while lithium batteries are still in the research and development stage and are in the growth stage in the market. Therefore, after the new national standard is implemented, lithium battery products are very likely to replace lead-acid battery products.
