英文摘要	Nano-sized LiMn2O4 materials are synthesized via a simple one-step solid-state reaction using lithium acetate and lithium oxalate as lithium sources, respectively. The physical and electrochemical properties of LiMn2O4 materials are investigated by X-ray diffraction, scanning electron microscopy and electrochemical measurements. The results show that both of the as-prepared materials are pure nano-sized LiMn2O4 with narrow particle size distribution. Compared with lithium oxalate, lithium acetate is propitious to improve the crystallinity and size distribution of nano-sized LiMn2O4. Besides, LiMn2O4 synthesized from lithium acetate shows low resistance, good ability to inhibit Mn3+ dissolution, long cycle life and excellent rate property. Finally, the adverse effect of nano-sized LiMn2O4, which has increased contact area between acid-containing electrolyte and LiMn2O4 cathode electrode to aggravate dissolution and corrosion behavior, is treated by Li2CO3 additive in electrolyte. Results show that electrochemical performance of nano-sized LiMn2O4 is improved, due to the fact that Li2CO3 additive can not only consume HF and other Lewis acid in the commonly used LiPF6-based electrolyte, but also decrease interfacial impedance to promote the migration of Li+ ions through cathode surface film.
