BMW creates a closed circuit to recycle lithium from the batteries of its electric cars

At BMW they are already doing their homework. The notable increase in the manufacturing costs of batteries for electric cars, mainly due to the increase in the acquisition prices of essential materials such as lithium or nickel, is causing companies spend much more effort recycling discarded batteries in order to give a second useful life to the mentioned components. From the Munich company they have already created a closed recycling circuit in China, hand in hand with their joint venture BMW Brilliance Automotive (BBA).

This new milestone is praised as an accomplished goal, which they had already had in their sights for quite some time in order to achieve climate neutrality in the coming years. As we have already mentioned, this recycling plant is located in China, where the state government requires that a series of high-voltage battery tracking systemsmainly so that once these have completed their useful life, they can be recycled and, in this way, the manufacture of new components is avoided, which will increase the CO2 emission figures on the eastern country specifically.

For this mentioned battery tracking system, BMW uses a series of encrypted codes to ensure the safety and optimal life of your component throughout its useful path. The very vehicles launched by BMW in recent years already have this quality coding and sampling system for their batteries.

Once these batteries have served their purpose, they are returned to BMW for evaluation; in this point from the German company they will decide if this component is optimized to be reused in some other purpose or, on the contrary, it must be disassembled and, the parts that are in good condition, be reused in new batteries. The aforementioned reused batteries are installed in electric forklift trucks or other industrial vehicles owned by BMW in its different plants, as well as in the BBA located in China.

In the case of recycled batteries, materials such as nickel, lithium or cobalt, among others, will be specifically extracted from these to be transferred to new batteries produced and which will then go to new production or development vehicles. However, since these raw materials can wear out after their vital use in commercial vehicles, most of what can be reused comes from batteries coupled in development vehicles, test systems, production rejects and, as last case, of production vehicles that reach the end of their life.

Thanks to this new closed circuit tour, from BMW they assure that it subtracts around 70 percent of CO2 emissions compared to what is emitted in the manufacture of a totally new battery. According to predictions estimated by the China Automotive Technology and Research Center, the volume of batteries removed and reused in the eastern country will reach 780,000 tons by 2025.

BMW aims to achieve climate neutrality by 2050 at the latest, since your idea is to reach this milestone, if possible, earlier. So the step of starting battery recycling, you can
