Perturbation Expansion of Potential of Charged Dielectric Sphere in Asymmetrical Electrolytes

A perturbation expansion for the electrostatic potential of a uniformly charged, dielectric sphere is extended to include asymmetrical electrolytes in the large radius limit. The potential, valid for qϕ/>T > 1 and small λD/a near the sphere, is solved in a similar manner to that for 1-1 electrolytes.
