摘要: Abstract Carbon coating always has a positive effect on improving the electrochemical performance of electrode materials for lithium ions batteries and its mechanism once drawn great attention, yet few studies offer model to elaborate it. In this study, we select PNb9O25 nanowires as anode material coat carbon them investigate how layer does affect performance. Meanwhile, theoretical proposed investigation mass transfer electron at surface PNb9O25. The result suggests that due presence layer, shows decent boost, leading improvement high current density.
