style="text-indent:25px">奧林巴斯-伊諾斯手持式光譜儀.河北便攜式三元鋰電池光譜儀</p>由此可見，鈦酸鋰電池基本原理，就是在充、放電的過程中，對應(yīng)的鋰離子在正負(fù)極之間來回的嵌脫，完成電池的充放電和向負(fù)載的供電。鈦酸鋰電池的充放電示意圖如圖所示： <p> 電池充電時，止極失去電子，鋰離子脫出，嵌入到負(fù)極中；負(fù)極嵌入鋰離子的同時得到電子成為富鋰態(tài)。放電時的過程正好相反。在Li+嵌入或脫嵌的反應(yīng)過程中，鈦酸鋰（Li4Ti5012）是一種理想的嵌入型電極材料，Li+插入和脫嵌對材料結(jié)構(gòu)幾乎沒有影響，因此被稱作“零應(yīng)變”材料，從而保證了其良好的循環(huán)性能。 </p> <p> 鈦酸鋰存在兩種不同相的分子結(jié)構(gòu)一—Li7TI5012與Li4TI3012。產(chǎn)生Li7TI5012的晶體結(jié)構(gòu)與Li4TI5012的晶體結(jié)構(gòu)均為尖晶石結(jié)構(gòu)，且晶格常數(shù)變化很小，同時體積變化也很小。能夠避免充放電循環(huán)中電極材料的來回伸縮而導(dǎo)致結(jié)構(gòu)的破壞，從而提高電極的循環(huán)性能和使用壽命，減少了隨循環(huán)次數(shù)的增加而帶來容量的衰減，使鈦酸鋰具有優(yōu)良的循環(huán)性能。河北便攜式三元鋰電池光譜儀</p><p
