In this work, Al-doped MnO 2 (Al-MO) nanoparticles have been synthesized by a simple chemical method with the aim to enhance cycling stability. At room temperature and 50 °C, the specific capacitances of Al-MO are well-maintained after 10 000 cycles. Compared with pure MnO 2 nanospheres (180.6 F g-1 at 1 A g-1), Al-MO also delivers an enhanced specific capacitance of 264.6 F g-1 at 1 A g-1.
