Carbon aerogels as electrodes in supercapacitor

0.2V, in the 2.5s,[link widoczny dla zalogowanych], the discharge current is increased rapidly by the 5mA 37mA, the discharge current increases quickly angle, carbon aerogels electrodes with a large current discharge capacity of carbon aerogels in Figure 9 the charge and discharge efficiency of the electrode curve shows that the range of 260 cycles. Always maintain the capacitor charge and discharge efficiency of 95, with a charge-discharge efficiency,[link widoczny dla zalogowanych], stable performance. Fig8Dischargecurveofcarbonaerogelelectrodeunderconstantpower \0.5mA when in the discharge specific capacitance of the electrode 121F / g, charge and discharge efficiency of 95,[link widoczny dla zalogowanych], with stable performance, charge and discharge efficiency, high current charge and discharge for excellent performance.
