N,N-Dimethylpyrrolidoium hydroxide (P11 OH) with polymer poly(tetramethyl ammonium acrylate) (PTMA) was investigated as an electrolyte in Ni/MH cells in this work. The efficiency and the performance of the electrolyte was discussed and elucidated with the performance of the cell. Their electrochemical characteristics had been investigated at different temperatures (25 °C and 50 °C) and different discharge current (15 mA g−1 and 30 mA g−1). The results show that the cell with electrolyte polymer-P11OH is dischargeable at these two temperatures, and a discharge capacity of 142 mAh g−1 at 25 °C has been obtained.
