不同二氧化錳制備尖晶石型錳酸鋰的研究 |
| 彭愛(ài)國; 皮銀安; 賀周初; 鄭賢福(湖南化工研究院; 湖南長(cháng)沙) |
| 摘 要：分別以化學(xué)二氧化錳(CMD)和電解二氧化錳(EMD)為錳源,制備尖晶石型錳酸鋰,通過(guò)X射線(xiàn)衍射技術(shù)對產(chǎn)物進(jìn)行了結構分析。在相同的合成條件下,以CMD為錳源制得的錳酸鋰晶型結構更加完美,電化學(xué)實(shí)驗結果顯示,其初始放電容量和循環(huán)性能均優(yōu)于后者,CMD是合成錳酸鋰的理想原料。 |

| 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. |
| Key words：Lithium-Manganese oxide; CMD; EMD |
