Abstract
Gel polymer electrolytes consisting of 25 wt.% P(VdF-co-HFP), 65 wt.% ethylene carbonate + propylene carbonate and 10 wt.% LiN(CF3SO2)2 are prepared using by a solvent-casting technique. The electrodes are for use in lithium-ion polymer batteries. The electrochemical characteristics of the gel polymer electrolytes are evaluated by means of ac impedance and cyclic voltammetry. The charge-discharge performance of lithium polymer and lithium-ion polymer batteries is examined. A LiCoO2 | gel polymer electrolyte (GPE) | mesocarbon microbeads (MCMB) cell delivers a discharge capacity of 146.8 and 144.5 mAh gâ1 on the first and the 20th cycle, respectively. The specific discharge capacity is greater than 140 mAh gâ1 for up to 20 cycle at all the current densities examined.
