Abstract A simple template-free solvothermal method has been developed to synthesize perovskite LaNiO 3 with hollow spherical structure. Appropriate annealing of the LaNiO 3 precursor is crucial to form uniform hollow structure. The obtained hollow structure significantly improves the ionic and electronic transportation leading to enhanced electrochemical performance. A high specific capacitance of 422 F g −1 has been achieved at a current density of 1 A g −1 with good cyclic stability. This facile method sets up a new synthesis route for novel perovskite oxides with hollow structure.
