摘要

用恒电流放电、循环伏安法和电化学阻抗谱(EIS)研究了PTFE对泡沫型氢氧化镍电极电化学性能的影响,发现PTFE的存在会增加电极的电化学反应电阻,降低电极反应的可逆性,从而使得电极的放电电位及容量有所降低,所以在制作粘结式电极的过程中应尽量减少粘结剂的用量.

Abstract

Research work was performed for the influences of PTFE on the electrochemical properties of foamtype Ni(OH)_2 electrodes by constant current discharge. CV and EIS method. Experimental results exhibit that the existence of PTFE would decrease the reversibility of electrode reaction and increase the reaction resistance of the electrode; thus lower the discharge potential and capacity, so PTFE should be added as little as possible during the preparation of pastetype electrodes.
