Abstract |
|
|
|
Li-ion battery for portable electronic devices and hybrid electric vehicles has gained great importance for energy storage today. However, there still exists an important issue in Li-ion battery, which is the capacity fading with cycling that largely limits the electrochemical performance and commercialization. Because of the existence of the specific layered structure of vanadium and molybdenum oxides, it is relatively easier to improve the conductivity by introducing high conductivity substance into the structure or coating them on the material surface, such as metallic ion, conductive polymer and so on. This review mainly focuses on some improvement strategies in vanadium and molybdenum oxide nanowire electrodes resulting in enhanced electrical transport and thus better electrochemical performances.
