Abstract: Based on the study of one dimension solvent,the nano-LiFePO4 for Li-ion battery anode was prepared via solvothermal method using polyethylene glycol (PEG) with different molecular weight in a water-polyethylene glycol (PEG) binary solvent.Research indicated:the introduction of solvent PEG had the effect of refining the material particles,effectively reducing the diffusion and migration pathway of Li ions.When PEG molecular weight was 600,the particle size was the smallest.At 0.1C rate,the specific discharge capacity was 147.1mAh/g.After 50 cycles,the capacity retention rate was 92.5%.Charge transfer resistance was 125Ω.
