Rechargeable battery positive electrode material formula
Elemental sulfur is a promising positive electrode material for lithium batteries due to its high theoretical specific capacity of about 1675 mAh g −1, much greater than the 100–250 mAh g −1 achievable with the conventional lithium-ion positive electrode materials [3]. The average discharge potential is around 2.1 V, and the complete lithium/sulfur (Li/S) system …
