中文摘要:

      为准确、快速测定锂离子电池正极材料LiCoxMn2-xO4中锰、钴的含量,给出了一个快速、简便的测定方法。提出了用络合滴定法测定锰含量,返络合滴定法测定锰、钴总量,再利用差减法计算出钴含量。相关的进行了酸溶解选择试验、锰含量测定条件选择试验、总量测定指示剂选择试验。最后,对锂离子电池正极材料LiCo0 1Mnl 9O4中的锰、钴含量进行了测定,结果表明,具有较高的精密度和准确度。

英文摘要:

      In order to measure the content of the manganese and cobalt in the cathode material LiCo_(0.1)Mn_(1.9)O_4 for Li-ion Battery accurately and quickly, we conducted the experiments for the choice of the acidic dissolving agent. Complexometry was adopted to measure the content of manganese by the condition-selection experiment.The measurement of the total content of manganese and cobalt was by returns complexometry. Finally, we made use of subtraction to compute the content of cobalt. According to the accurate result in this paper, we conclude that it is a simple, prompt method of precision.
