Controllable Morphology Tailoring with Solvothermal Method Toward LiMnPO4/C Cathode Materials for Improved Performance and Favorable Thermostability
文献摘要：
An environmentally friendly method for the synthesis of LiMnPO4/C anode material for lithium-ion batteries by solvothermal method is introduced.The modification of the morphology of this precursor is altered by changing the ratio of the condition-ing solvent(water-ethylene glycol solution)and the order of material addition.Ethylene glycol(EG)exerts a considerable influence on synthesizing LiMnPO4/C flake-like nanocrystal,which benefits the extraction/insertion reaction of lithium ions and improves the electrochemical activity and electrochemical performance of LiMnPO4/C material.When the solvent composition is H2O∶EG=1∶3,exhibiting exceptional charge/discharge performance and rate capability,the specific discharge capacities are 155.8,153.7,148.8,141.4,129.5,and 112.6 mAh g-1 at the 0.1,0.2,0.5,1,2,and 5 C rates,respectively.When the charge-discharge rate returns to 0.1 C,the LiMnPO4/C material shows a reversible discharge specific capacity of 153.7 mAh g-1.Differential scanning calorimetry(DSC)tests verify that the thermodynamic stability of the prepared LiMnPO4/C(LMP)and commercial LiFePO4(LFP)materials is better than that of commercial nickel-cobalt-aluminum(NCA)ternary materials.These prepared LiMnPO4/C composites have high electrochemical capacity and cycle stability.
