Effects of temperature on Li nucleation/deposition behaviours and electrochemical performances are thoroughly investigated. Higher temperature leads to lower nucleation density with larger deposit sizes due to the reduced surface migration barrier and accelerated ion diffusion, plus better lifespans and coulombic efficiency owing to the relatively conducive morphology characteristics and a favorable SEI layer.
深入研究了温度对锂成核/沉积行为及电化学性能的影响。较高温度会导致成核密度降低，沉积物尺寸增大，这是由于表面迁移势垒降低和离子扩散加速所致，此外，由于相对有利的形貌特征和良好的固体电解质界面（SEI）层，电池具有更好的寿命和库仑效率。
