If the battery is removed after charging, then the charge stored in the capacitor remains. constant.

q =

constant
New capacitance

C^{'} = \frac{ε _{0} A}{d ^{'}}

d^{'} < d

Potential difference between the plates is given by

V^{'} = \frac{q}{C ^{'}}

V^{'} \propto \frac{1}{C ^{'}}

As capacitance decreases, so potential difference increases.
