摘　　要：采用丁酮对以ＳＢＳ为粘合剂的电极进行了化学处理，对处理效果进行了考察，探讨了作用机理．实验结果表明，经丁酮处理后，合金表面残留的溶剂（如松节油）被溶出，提高了电极性能，尤其是大电流放电能力和活化速度．电化学测量结果表明，这种处理提高了电极的电催化活性和扩散系数，降低了电极的电化学反应阻抗．The solvent, e.g. turpentine oil, remained on the surface of the MH electrode using SBS as binder was dissolved out after dipping into butanone and the electrode behavior especially the rate dischargeability and the activation were improved significantly. Electrochemical measurements showed that the dipping increased electrochemical catalysis activity and diffusion coefficient of the MH electrode, but decreased its electrochemical reaction resistance.
