Low-temperature tolerant lithium-rich manganese-based cathode enabled by facile SnO2 decoration

SnO 2 -decorated Li[Li 0.144 Ni 0.136 Co 0.136 Mn 0.544 ]O 2 (S-LLOs) demonstrates a high capacity and excellent cycle life at low temperatures, which is attributed to the low activation energy of Li + diffusion in the CEI layer and charge transfer.
