EV battery recycling: Lucid Motors aims to give lithium-ion batteries a second life in energy storage systems | message

With lithium-ion batteries, 70 percent of the capacity is retained after first use
Identical to the battery cells of the storage systems
No technical limitations to worry about
According to the technology news portal “TechCrunch”, lithium-ion batteries normally retain around 70 percent of their energy capacity after they are removed from electric vehicles at the end of their service life, and can therefore be used in a further life cycle, the so-called “second life”. to be used for another decade. Eric Bach, chief engineer and senior vice president of product at Lucid Motors, spoke about the possibilities of reuse in an interview with “TechCrunch”.
Reuse in storage systems
It will be the first Electric car Lucid Motors is not expected until the second half of 2021, but the company is already looking for ways to reuse the lithium-ion batteries in vehicles after they have been used for the first time. According to Bach, one possible solution would be to recycle the batteries or the still functional battery cells in energy storage systems. The company is already investigating this, as Lucid Motors plans to provide energy storage systems for private and commercial customers in addition to electric vehicles. As Bach told TechCrunch, the company has already developed the first prototype of a stationary battery storage system with an output of 300 kilowatt hours in its technical laboratory.
According to TechCrunch, the battery cells used in the electric vehicles are identical to those that the company intends to use for energy storage within the battery storage systems, which makes reuse possible in this regard. In addition, according to Eric Bach, there are no technical restrictions that would prevent Lucid Motors from replacing the battery cells in its storage systems with battery cells from used electric vehicles.
Removal of the batteries from the vehicles
As Bach explains to TechCrunch, Lucid Motors plans to remove used batteries from electric vehicles after the vehicles have reached the end of their life cycle and customers trade in their vehicles. As soon as the batteries have been returned to Lucid, the company must remove the individual battery cells and subject them to a quality check. The sensors integrated in the vehicles have data that are intended to help determine the status of the individual battery cells. Depending on the condition, the battery cells can then be placed and used again in another product, for example in the energy storage systems, according to the process description by Lucid Motors’ chief engineer.
Lucid Motors is not alone with this idea: Other car manufacturers such as General Motors, Ford and AUDI have already started Second Life pilot projects.
