摘　　要：采用田口方法对锂离子电池石墨负极改性过程进行实验设计,将酚醛树脂、石墨、溶剂、包覆量、蒸发温度、碳化温度、碳化时间作为影响因素,可逆容量作为评价指标,建立多因素单指标的实验设计问题。利用均值响应主效应图得出影响评价指标的敏感因素,并通过均值响应及信噪比响应确定了最佳工艺参数。最后通过实验证明,在该方法获得的最佳工艺参数条件下,可逆容量达到了360mAh/g,相比初始值320mAh/g有较大提高。Taguchi method was used in the experimental design process of graphite anode modification for lithium-ion battery. In the process,an experimental design problem with a single indicator and multi-factors was established, which took the phenolic resin, graphite, solvents, coating volume, evaporation temperature, carbonization temperature and carbonization time as the influencing factors, and the reversible capacity as the evaluation index. Then, sensitive factors which affected the evaluation index were obtained based on the main effect map of mean response, and the best process parameters were determined via adopted in mean response and signal to noise ration. Finally, experiments had proved that the reversible capacity had reached to 360mAh/g, and was greatly enhanced compared to the initial value of 320mAh/g, under the conditions of adopting the best process parameters.
