Optimization of gel electrolyte using dual quadratic rotary regression orthogonal design

为了优化胶体电解液的合成工艺,采用二次正交旋转组合设计分析了气相二氧化硅含量和离子液体添加剂加入量对于胶体电池品质(粘度、电导率)的影响,并建立了相应的预测模型。方差分析的结果表明:气相二氧化硅含量和离子液体添加剂加入量对于胶体电解液粘度和电导率两项指标均有显著影响。优化的工艺参数为:气相二氧化硅含量为2.5%;离子液体添加剂加入量为0.025mL。对应的相对粘度和电导率的预测值分别为:相对粘度3.189和电导率1.4775S/m。实验证明:应用二次正交旋转组合设计所得到的胶体电池合成工艺参数是可行的。

In order to optimize the gel electrolyte synthesis technology,the dual quadratic rotary regression orthogonal design was employed to analyze the effects of amount of fumed silica and value of ionic liquid additive on the gel battery qualities including viscosity and conductivity,and the prediction models were also established.The analysis of variance shows that the amount of fumed silica and value of ionic liquid additive significantly affects the response variables.The optimum conditions obtained are 2.5% of amount of fumed silica and 0.025 mL of value of ionic liquid additive.The values predicted by the models for the relative viscosity and conductivity under optimized conditions are 3.189 and 1.477 5 S/m respectively.These values are verified by experiment.
