| 摘 要： | 分别以化学二氧化锰(CMD)和电解二氧化锰(EMD)为锰源,制备尖晶石型锰酸锂,通过X射线衍射技术对产物进行了结构分析。在相同的合成条件下,以CMD为锰源制得的锰酸锂晶型结构更加完美,电化学实验结果显示,其初始放电容量和循环性能均优于后者,CMD是合成锰酸锂的理想原料。

| Abstract: | The spinel LiMn_2O_4 were synthesized form CMD and EMD, the structure of LiMn_2O_4 were investigated by XRD. The resultant LiMn_2O_4 which synthesized from CMD show perfect spinel structure than those which synthesized from EMD under the same synthetic conditions, and the result of the electrochemical characterization show that they also have more large initial discharge capacity and show better charge/discharge performance. CMD is a good material to produce LiMn_2O_4. |
