摘要
The confinement within carbon nanotubes (CNTs) improves the electrochemical reversibility of CNT-confined MnO(2) nanoparticles and benefits their capacitive enhancement, which exhibit a specific capacitance of 225 F g(-1) for the composites and MnO(2) normalized capacitance as high as 1250 F g(-1)
