PNNL study identifies one of the mechanisms behind Li-sulfur battery capacity fade; the importance of electrolyte anion selection

Green Car Congress

Lithium-sulfur batteries—comprising a sulfur cathode and Li metal anode—are widely seen as a very promising next-generation electric energy storage system due to their very high theoretical specific energy (2550 Wh kg −1 ) and energy density (2862 Wh L −1 ). Background. Ji-Guang (Jason) Zhang, study leader.
