采用SiO_2作助磨剂的机械力化学法提高废旧锂电池中钴和锂的浸出率。实验结果表明，在柠檬酸介质中，当SiO2/LiCoO 2质量比为1：1，磨矿速度为500 r/min，磨矿时间为30 min时，钴和锂的浸出率分别为94.91%和97.22%。表征结果表明，机械力化学研磨处理后，LiCoO_2的表面性质发生了变化，这是由于在LiCoO_2表面生成了新的表面。同时，LiCoO_2的不完全配位原子结构和晶格结构缺陷也是导致其活化的主要原因。炭黑在机械力作用下对钴离子的还原作用提高了钴离子在柠檬酸溶液中的浸出率。实验结果表明，该工艺可有效地从LiCoO_2中回收钴和锂。
A mechanochemical method with SiO_2 as the grinding aid was used to enhance the leaching efficiencies of Co and Li from spent lithium batteries(LIBs). Experiment results show that the optimal leaching efficiencies of 94.91% for Co and 97.22% for Li were obtained under the parameters of SiO_2/LiCoO_2 mass ratio of 1:1, grinding speed of 500 r/min and grinding time of 30 min in citric acid. Characterization results indicate that the surficial properties of LiCoO_2 were changed after mechanochemical grinding treatment due to the newly generated surfaces on LiCoO_2. Meanwhile, the incompletely coordinated atomic structure and defective lattice structure lead to the activation of LiCoO_2. The reduction effect of carbon black on Co~(3+) under the action of mechanical forces increases its leaching efficiencies in the citric acid solution. The proposed process was found efficiently to recover Co and Li from LiCoO_2.
