A lithium/polysulfide semi-solid rechargeable flow battery with high output performance†
Abstract
The feasibility of a semi-solid flow battery with polysulfide as catholyte is demonstrated, which gives a power density of 1.823 mW cm−2 at 4 mA cm−2. Compared to Li–S batteries with sulfur as cathode, the feasibility and flexibility using polysulfide as catholyte in flow-through mode create new potential for the practical application of conventional Li–S batteries.
