文摘Beyond a doubt,Li ion battery(LIB)has reshaped our livesfundamentally since its advent in 1990s.After 30 years’optimization,the energy density of LIBs based on intercalation chemistries has approached the limit of~300 Wh/kg.Any further improvement of energy density calls for new battery chemistries,among which Li-S batteries are regarded as one of the most promising energy storage alternatives because of the high theoretical specific energy(2600 Wh/kg)and low cost of the sulfur since their renaissance in 2009[1].
