2 . aqueous solution electrolyte such sulphuric acid starts to decompose about iv or so , but nonaqueous solution such as 1 mol / 1 eunbf4 / pc ca n ' t decompose below 2 - 5v . at the same current , the capacity of capacitors with monaqueous electrglyte is higher than that of aqueous electrolytes , but the former have high internal resistance , the latter has low resistance but it erodes the systems 由于水系电解质h _ 2so _ 4的耐分解电压只有1v左右，而非水系电解质1mol 1et _ 4nbf _ 4 pc的为2 . 5v左右，在相同的电流下充放电时，电解质为非水系电解质的电阻大，这样增大了电容器的内阻；而水系电解质h _ 2so _ 4的电阻低，但是它腐蚀设备。
After finished the cyclic voltammetry experiments , the results showed that iron steel grid can act as good current collector in the aqueous electrolyte . while the scan rate was fall in the range of 0 . 5 - 4 . 0mv / s , electrochemical reaction of the lithium insertion / extraction in the solid phase was kinetically limited by the diffusion of lithium ions . after 40 cycles in aqueous electrolyte the discharge capacities of sample of s13 reached 77mah / g , and showed good cycle performance 在水溶液中不锈钢网可以作为电极的集流体，在0 . 5 - 4 . 0mv / s的扫描速度范围内，锂离子在尖晶石锂锰氧化物的嵌入和脱嵌的电化学反应在动力学上是受锂离子在固相中的扩散所控制，充放电实验显示样品s13在水电解液中经过40个循环后达到77mah / g的放电容量，具有很好的循环稳定性。
