According to foreign media reports, this week, Tesla confirmed that it is developing a "unique battery recycling system." The company believes that in the long run, the system can save "a considerable amount of money."
On April 15th local time, Tesla released a new "impact report". The report shows that the Tesla fleet has more than 500,000 electric vehicles, helping to prevent 4 million tons of carbon dioxide from being emitted to In the atmosphere. In the report, Tesla also elaborated on the idea of ​​battery recycling: "I often hear people asking," What happens when a Tesla car's battery pack is exhausted? Fossil fuels and lithium-ion batteries are both energy sources, but the difference between them is that fossil fuels can be extracted and used once, and the materials in lithium-ion batteries can be recycled and reused. When oil is mined underground, After chemical refining and combustion, harmful gases are released into the atmosphere, but such gases cannot be recovered and reused. In contrast, battery materials are refined and then put into batteries, but they can still be used after the end of battery life. Retain it and be able to recycle the valuable materials and reuse it repeatedly. "
In terms of battery recycling, most car manufacturers are currently focusing on the application after the battery pack has expired, but Tesla is different from them. Automakers such as Hyundai, BMW and Renault have announced that they will use old battery packs in energy storage systems instead of recycling battery packs to produce new battery packs, some of which are already using recycled old battery packs for Energy storage system.
Tesla said that because the battery pack has reached the end of its life, a large number of battery packs have not yet been recovered, but Tesla is recycling several battery packs for "R & D, production, quality control and service operations." The company said it is working with third-party battery recyclers around the world to process all used batteries and recycle valuable metals. Work with recycling partners to ensure responsible disposal of materials that have no value or cannot be recycled in the battery.
But this is obviously only a temporary solution, because Tesla said it is also developing a battery recycling system at Gigafactory 1 in Nevada. Tesla said in the report: "Tesla is developing a unique battery recycling system in Super Factory 1, which can process both battery production waste and used batteries. Through this system, key minerals such as lithium and cobalt are The recovery rate of all metals such as copper, aluminum and steel in the battery will be the highest. All the above materials will be recycled in the form most suitable for the production of new batteries.
Currently, there are several companies studying how to recover key minerals from batteries during the recycling process. Recently, American Manganese has successfully achieved a high recovery rate in the recycling of lithium ion battery cathode materials at a pilot recycling plant.
Tesla believes that its closed-loop battery recycling process will save considerable money, because the cost of large-scale recycling and reuse of battery materials is much lower than the cost of buying and transporting new materials.
In addition, Tesla co-founder and current chief technology officer JB Straubel founded a materials recycling startup two years ago. It is believed that the company has a strong relationship with Tesla.
