New strategy proposed for ultra-long cycle lithium-ion battery

https://phys.org/news/2022-12-strategy-ultra-long-lithium-ion-battery.html

"sulfur doping and in-situ growth of coherent spinel phase synchronously on the surface of lithium-rich manganese-based materials combining with oxygen vacancy optimization strategies... after 600 cycles, the capacity retention rate of coin battery can reach 82.1%, the energy density of the packed full battery assembled with commercial graphite anode can reach 604 Wh kg-1, and the capacity retention rate is 81.7% after 140 cycles"
