【摘要】：錳酸鋰具有尖晶石和層狀兩種結(jié)構(gòu),而層狀LiMnO_2具有無毒、安全、理論容量高等優(yōu)點(diǎn)。以專用的MnO_2在空氣中高溫焙燒分解Mn_2O_3,與電池級LiOH·H_2O為原料,采用高溫固相法,合成層狀錳酸鋰,其最佳合成條件為:鋰錳配比為1.03,球磨均勻,經(jīng)600℃溫度,氬氣保護(hù)氣氛下,合成8h,合成的層狀LiMnO_2材料,其首次充放電容量分別達(dá)到279mAh/g和171mAh/g,經(jīng)20次循環(huán)后容量保持率為96.2%。合成的層狀LiMnO_2材料具有相對較好的電化學(xué)性能。
[Abstract]:Lithium manganese oxide has spinel and layered structure, while layered LiMnO _ 2 has the advantages of non-toxic, safe and high theoretical capacity. The layered lithium manganate was synthesized by high temperature calcination of Mn2O3 with LiOH H2O as raw material and battery grade LiOH H2O in the air. The optimum conditions were as follows: the ratio of lithium to manganese is 1.03, the ball milling is uniform, and the temperature is 600 鈩，
