Researchers at Fudan University in China have devised a lithium injection method to revitalize degraded lithium-ion batteries. This involves injecting a carrier molecule that releases lithium ions, effectively restoring battery capacity and extending lifespan.
The method addresses the issue of inactive lithium deposits formed during charge-discharge cycles. The carrier molecule dissolves in the electrolyte, releasing lithium ions and improving battery performance. Testing showed an increase in battery life from 1,500 to 12,000 cycles.
This breakthrough could drastically extend the lifespan of EV batteries, reducing the need for frequent replacements and decreasing electronic waste. It could also lower consumer costs and promote more sustainable electric transport. The technology's scalability for industrial production is currently being explored by the researchers.
The main challenge lies in scaling the method for industrial production and integration into commercial supply chains. While the long-term market impact is uncertain, the potential is substantial for revolutionizing the electric vehicle industry and promoting more sustainable practices.
