Tsinghua team develops bio-inspired self-healing sulfur electrodes; almost no capacity decay after 2000 cycles

Green Car Congress

The researchers suggest that a comprehensive understanding of this healing process could further guide the design of novel healing agents toward high-performance rechargeable batteries. More importantly, similar to plasmin, the ability of polysulfides to self-regenerate guarantees their persistency to work in Li−S batteries.
