According to U.S. media, throwing away used lithium batteries will damage the environment, and the benefits of recycling will not be great. China's solution is simple, but it may have a profound impact on the environment.
According to the report of the US Bloomberg News website on March 11, China hopes to become Detroit in the electric vehicle industry. In 2018, China's new energy vehicle sales are expected to reach 1 million, and the government has a big plan to promote its development. But this kind of gratification The trend has also brought about a distressing side effect: China currently uses more lithium-ion batteries than any other country. How to deal with these batteries?
Reported that since the 1990s, lithium-ion rechargeable batteries have been shown to effectively store large amounts of energy in small spaces. This makes them suitable not only for cars, but also for consumer electronics, such as power tools and iPhones. As the world It is no longer a natural thing for China to become the largest manufacturing country for lithium-ion batteries in the major countries that manufacture and consume such products.
How to deal with these discarded batteries? This problem is getting trickier, and recycling seems like a very good option. The supply is almost endless, the government has provided generous subsidies, and China has the largest and most advanced battery in the world. Recycling plant.
The report stated that, however, lithium-ion batteries have a strange feature: When devices using lithium batteries (such as mobile phones, electric drills, automobiles, etc.) cannot be used, their internal batteries can still be used. The estimated figures in different cases are different. The same, but generally speaking, electric cars have at least 70% of their capacity after 10 years of use, which is why the use of old batteries in new equipment has become an increasingly popular choice.
According to reports, the industry as a whole is still informal, and the industry is huge. This is reflected in the global pricing of used batteries. According to a recent analysis of the lithium ion market, Hans Melin said that in China, The recycled battery will be bought by the refurbisher at a price of 4 US dollars per kilogram (about 25.3 yuan); the price of a battery more suitable for recycling is only 1.5 US dollars per kilogram (about 9.5 yuan).
Companies around the world are beginning to realize the potential of this approach. BMW has recently built an old battery storage farm that will deploy up to 700 used battery packs to capture the power generated by windmills. Running 2 million telecommunications Tower's China Tower Co., Ltd. plans to replace the current use of lead-acid batteries with old lithium-ion batteries obtained from manufacturers.
According to reports, this is what China encourages. In February, China released a temporary method for the management of the recycling of power batteries for new energy vehicles. Switching these batteries for other energy projects can further reduce the impact of electric vehicles on the environment. Better Yes, increasing the supply of used batteries should reduce storage costs. According to Bloomberg New Energy Finance estimates, the cost of switching to batteries in 2018 would be US$49 per kilowatt-hour (about RMB310), while the new battery would be per kilowatt-hour. 300 US dollars (about 1897 yuan).
The report stated that, in addition, the benefits of this change may be enormous. Merlin predicts that by 2025, 60% of old car batteries will be used to store energy and then recycled. This should effectively reduce costs, further Reduce emissions and reduce people’s demand for new batteries and related raw materials. In other words, not only is China managing old batteries – it is also likely to be an example of how other countries in the world can use electricity sustainably.
