Researchers have developed a low-temperature plasma process that enables the direct recycling of battery cathodes. By using oxygen radicals to remove carbon and fluorine impurities, the method allows for more efficient re-lithiation without destroying the cathode structure through smelting or grinding. Experimental results on NMC pouch cells showed 87% capacity retention after 1,100 cycles. This approach reduces energy consumption compared to traditional pyrometallurgy and helps preserve the integrity of sensitive cathode materials.
