In new work, scientists describe a lithium?sulfur battery prototype using commercially viable micron-sized sulfur as cathode materials but with unprecedented cycling life that has never been achieved before. This success in achieving exceptionally long battery life is ascribed to a concept of self-healing. By mimicking a biological self-healing process, fibrinolysis, the team introduced an extrinsic healing agent, polysulfide, to enable the stable operation of sulfur microparticle (SMiP) cathodes.
