Activated carbon monolith (ACM) was made from rubber wood for supercapacitor applications by using two activators, namely KOH and HNO3. Carbonized sample were by N2 gas at a temperature of 600º C and were physically activated by CO2 gas at 800º C for 2 hours. KOH solution of 1, 3 and 5 molar was used as chemical activation solution. ACM electrodes were tested in a two-electrode system, which …
