"enhancing cathode kinetics increases sulfur utilization... utilizing irreversible delithiation metal sulfide properties... Li2S imprinting defects constructed in MS pre-embedding Li2S with lithiation/delithiation process and alcohol wash Li2S removal, forming sulfur vacancy in catalyst, enabling catalyst selectively bind to target product Li2S... cycled stably 100 cycles, energy density >300 Wh/kg based on total mass (502 Wh/kg using this catalyst)... solves Li2S dissociation problem, enabling industrialization of Li-S batteries"
