中文摘要：

采用脉冲激光沉积法在不锈钢基片上制备了LiF-Ni纳米复合薄膜，用充放电和循环伏安实验测量了该薄膜的电化学性能．首次充电容量为107mAh·g^-1，它对应第一次释放锂的过程．在充放电循环过程中，锂的嵌入、脱出通过非原位高分辨电子显微和选区电子衍射得到证实．这一结果为LiF可以由过渡金属Ni驱动分解提供了直接的实验证据．

英文摘要：

Nanocomposite of LiF-Ni with a highly heterogeneous mixture was fabricated using pulsed laser deposition （PLD） method, and it exhibited remarkable electrochemical activity, The electrochemical reaction of LiF-Ni nanocomposite thin-film electrode with Li was firstly investigated by the discharge/charge and cyclic voltammetry. The initial charge capacity of the LiF-Ni/Li cell was found to be 107 mAh·g^-1 The process of releasing Li from the asdeposited LiF-Ni nanocomposite thin films was confirmed by ex-situ high-resolution transmission electron microscopy and by the selected area electron diffraction measurements. These results provided a direct experimental evidence to support the electrochemical decomposition of LiF driven by the transition metal Ni in the potential range from 1.0 V to 4.0 V. LiF-Ni nanocomposite electrodes could be a novel candidate that could be used as an appropriate for Li storage material.
