一次粒子在鋰離子電池充放電中會否被粉碎
|
||
|
看一篇文獻(xiàn)中這樣說: However, the practical use of SnO2 powders as a negative electrode for lithium-ion batteries is still hindered by several major problems: poor cycleability, resulting from the severe volume expansion and contraction during the alloying-dealloying cycles with Li+ ions and the associated charge transfer process, and the pulverization and the agglomeration of primitive particles, which drastically reduces the total entrance/exit sites available for Li+ ions。 紅色的部分是說一次粒子被粉碎嗎,我查的資料說砂磨或者球磨最多能減少到粒子的極限尺寸即粒子的一次粒子尺寸,這里是什么意思。難道說是原始顆粒尺寸嗎? 但后面又有一段話: Decreasing the primary particle size to a few nanometers while retaining a homogeneous size distribution however still remains a crucial issue for most of the applied synthesis techniques. 這里面的紅色字體是一次粒子尺寸還是原始粒子尺寸合適呢? 謝謝大家 |
