["A 'Single Injection' Extends Lithium Battery Lifespan by Tenfold: Fudan's New Achievement Featured in 'Nature'"] When the lifespan of a lithium battery is nearing its end, injecting it with a new molecule can restore its original charging capacity. This breakthrough even enables batteries, which originally could only guarantee 6-8 years or 1,000-1,500 charge-discharge cycles, to sustain 10,000 charge-discharge cycles while maintaining a health level almost identical to their ex-factory state. This latest achievement was accomplished by the team of Huisheng Peng and Yue Gao from the Department of Macromolecular Science, the National Key Laboratory of Polymer Molecular Engineering, the Institute of Fiber Materials and Devices, and the Intelligent Center of Polymer Science at Fudan University.
