英文摘要	The rate performance of lithium manganese phosphate is seriously tarnished by its sluggish surface kinetics, which could be addressed by LiFePO4-surface coating. For a higher energy output, here we explore thinner coating layers with 10% and 5% LiFePO4 via the lab-developed DMSO assisted method. The core-shell structured 0.9LiMnPO(4)-0.1LiFePO(4)/C maintains a high specific capacity, 153, 148 and 140 mA h g(-1) under 0.1, 1 and 5 C respectively, which are the best results for this composition till date. As for 0.95LiMnPO(4)-0.05LiFePO(4)/C, the discharge capacity is lower than 110 mA h g(-1) even in 0.1 C, which cannot meet the requirements of practical application. Our approaches push the manganese ratio of LiMnPO4-based composite to 90% from 80%, further improving the energy-density of the olivine phosphates.
