ZnCl2 activation research has been done on the preparation of activated carbon based mesoporous Rubber Wood Saw Dust (RWSD) for supercapacitor cells applications using physical and chemical activations. Physical activation was done by using CO2 gas at a temperature of 900 °C for 2 hours. Chemical activation using an activator substance of ZnCl2 solution. Mass ratio of carbon and ZnCl2 was 1:1,…
