Thermodynamic properties of Reissner–Nordström–de Sitter quintessence black holes

Mass, electric charge, and temperature of black holes in the Reissner–Nordström–de Sitter quintessence (RN–dSQ) spacetime are obtained. The heat capacities of the RN–dSQ black hole for certain electric charge and mass are analyzed. The electrostatic energy and the dark energy in the RN–dSQ black hole are also calculated.
