| Abstract: | In this paper,the surface of Ni-MH battery separator was modified by hollow cathode remote plasma.The effects of the working parameters on the separator＇s properties were studied systematically.The IR and SEM were used to analyze the chemical composition and the surface morphology.The change of electrochemistry properties before and after treatment was tested by electrochemistry measurement.The results showed that the hydrophilic group was found on the surface of Ni-MH battery separator after hollow cathode remote plasma modification,the wettability of the separator was greatly improved,so that the battery＇s property was improved obviously. |
| Keywords: | Ni-MH battery separator hollow cathode remote plasma surface modification |
