What is the reverse current of the battery
Note that in metals, the current is conducted by electrons, but by definition, in the opposite direction to the electric current. In other materials, charge carriers can be negative or positive. By convention, the current is always assumed to flow in the direction of positive charge, disregarding the material and mechanism for its conduction.
