Researchers have developed a direct regeneration technology for electric vehicle batteries that restores capacity to over 95% of its original state. Unlike traditional methods that require crushing or chemical decomposition, this process repairs electrode materials without fully dismantling them.
The new technique focuses on replenishing lost lithium ions and performing heat treatment to reconstruct damaged crystal structures in the electrodes. This approach avoids the high energy consumption and carbon emissions associated with traditional hydrometallurgical or pyrometallurgical recycling processes.
Experimental results confirm that batteries treated with this method achieve electrochemical performance, cycle stability, and safety standards comparable to new units. By eliminating the need to reduce materials to raw metals, the process significantly reduces chemical usage, energy costs, and overall recycling time.
While the technology shows promise for the supply chain, experts note that scaling it for industrial use requires addressing engineering challenges. These include the automated disassembly of used batteries and the standardization of battery conditions before the repair process begins.
