摘要
Abstract
Manganese dioxide/titanium dioxide/mesoporous carbon composite materials were synthesized via a hydrothermal reaction and air electrode was prepared with composite materials. The crystal structures and the surface morphologies of the composite materials were characterized by X-ray diffractometer (XRD) and scanning electron microscope (SEM). Cyclic voltammetry was adopted to investigate the electrochemical behaviors. The experimental results show that the highest degree of crystallinity can be achieved for the composite material prepared on the condition of 160℃ and its air electrode has good electrochemical reversibility. The charge-discharge of lithium-air batteries with air electrode was tested. The first discharge performance of lithium-air batteries is up to 1 331 mAh/g.关键词
