Polyaniline (PANI) hollow microspheres were fabricated by self‐assembly method and further doped with cerium ions (Ce 3+ ). The constitution and morphology of Ce 3+ ‐doped PANI (PANI/Ce 3+ ) were characterized by Fourier transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM) and Energy dispersive X‐ray spectroscopy (EDX) etc. Furthermore, a 2016‐type buckle capacitor was assembled and PANI/Ce 3+ was employed as electrode material. The electrochemical properties of PANI/Ce 3+ capacitor were measured by cyclic voltammetry (CV), galvanotatic charge‐discharge (GCD), electrochemical impedance spectroscopy (EIS) and so on. The PANI/Ce 3+ capacitor exhibited high specific capacitance and small resistance. The specific capacitance of PANI/Ce 3+ was 248.2 F/g at current density of 1 mA/cm 2 .
