【導(dǎo)讀】因其低的理論容量阻礙了它的應(yīng)用。因此,本文采用溶膠—凝膠法合。采用XRD、SEM分析材料的晶體結(jié)構(gòu)和表面形貌;通過循環(huán)伏。明,材料晶體結(jié)構(gòu)的特征峰與尖晶石型鈦酸鋰的標(biāo)準(zhǔn)圖譜基本一致,構(gòu),但當(dāng)摻雜量較大時,材料中會有一定量的雜質(zhì)出現(xiàn)。鋰電池的負(fù)極材料比碳負(fù)極材料更安全。采用同樣的方法對鈦酸鋰進(jìn)行Fe3+摻雜。電化學(xué)測試結(jié)果表明,雜比例為5%時電化學(xué)性能較好。進(jìn)一步對鈦酸鋰進(jìn)行納米金剛石摻。了人們的廣泛關(guān)注,發(fā)展非常迅速。因此國內(nèi)外的學(xué)者們紛紛對鋰電。鈦酸鋰的低電導(dǎo)率、高倍率時低可逆容量問題是制約。這種鋰離子電池負(fù)極材料商業(yè)化的瓶頸性難題之一。
