| Abstract: | The test capacitors composed of a pair of carbon electrodes and the novel room temperature ionic liquids based on lithium bis(oxalato)borate(LiBOB)and urea as electrolyte were assembled.A high specific capacitance of 92F/g estimated by galvanostatic charge/discharge measurement is obtained.The working voltage of the test capacitors reach above 2.0V.After 2000 charge and discharge cycles,the capacity loss is just 8% of the initial discharge capacity.The room temperature ionic liquid shows good electrochemica... |
