Hybridized microparticles composed of mesoporous manganese dioxide (MPMO) core and fullerene C60 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 C60 NCs contributes to the reduction of IR loss to enhance the power density. The coating of MPMO with C60 NCs resulted in a greatly improved pseudocapacitor performance, owing to the improved conductivity to allow fast charging/ discharging.
