Supercapacitors are extensively researched due to their high power density, long cycle life, and their high output power and high energy storage functions. Graphene has a large specific surface area and high electrical conductivity, making it good for use as electrodes in coin cell supercapacitors. Boron is considered a good chemical element as a dopant material. This article aims to analyze the use of reduced graphene oxide and doped graphene oxide boron as electrode materials for asymmetric and symmetric coin cell supercapacitors. The method used is experimental with the reduction of graphene oxide and doped graphene boron which is used as the cathode and anode coin cell supercapacitor. The reduction is carried out by a pyrolysis process in an atmosphere of argon and hydrogen at high temperatures. The results show that graphene can be doped with boron and can be used as electrodes (cathode and anode) in symmetric and asymmetric coin cells. The capacity value of the asymmetric coin cell is the median value of the symmetrical coin cell of the cathode and anode materials.
