Abstract: The interaction energies between two similar plane double layers forCaCl2-type asymmetric electrolytes at positive surface potential are expanded in the power series at lower potential and smaller absolute value of integral constant as well as higher potential and larger absolute value of integral constant, respectively. When dimensionless surface potentialy0≤ 20, the number of the series terms required to obtain the interaction energies with six significant digits are not more than eight if higher potential expressions are combined with lower potential expressions. The accurate numerical results are given and they can be used to check up the validity of approximate expressions that will be obtained. The present results are also fit forNa2SO4-type asymmetric electrolytes at negative surface potential.
