碳在李 ₂ MnSiO ₄ 到作为阴极材料改进电气化学的表演，哪个被热处理在 700 点跟随的答案方法综合 ?荰 吗？？

英文摘要：

Carbon was coated on the surface of Li_2MnSiO_4 to improve the electrochemical performance as cathode materials, which were synthesized by the solution method followed by heat treatment at 700 ℃ and the solid-state method followed by heat treatment at 950 ℃. It is shown that the cycling performance is greatly enhanced by carbon coating, compared with the pristine Li_2MnSiO_4 cathode obtained by the solution method. The initial discharge capacity of Li_2MnSiO_4/C nanocomposite is 280.9 m Ah/g at 0.05 C with the carbon content of 33.3 wt%. The reasons for the improved electrochemical performance are smaller grain size and higher electronic conductivity due to the carbon coating. The Li_2 MnSiO_4/C cathode material obtained by the solid-state method exhibits poor cycling performance, the initial discharge capacity is less than 25 m Ah/g.
