Hybridized microparticles composed of mesoporous manganese dioxide (MPMO) core and fullerene C-60 nanocrystal (NCs) shell were fabricated by co-reprecipitation method. Double layer capacitance as well as fast surface redox reaction of MPMO contributes to increase the energy density, whereas C-60 NCs contributes to the reduction of IR loss to enhance the power density. The coating of MPMO with C-60 NCs resulted in a greatly improved pseudocapacitor performance, owing to the improved conductivity to allow fast charging/discharging.
