TLDR
In this paper, a conductive polymer surface coating on silicon nanowires (Si NWs) is used to improve the cycling stability of Li-ion battery anode material, which is attributed to the conductive coating maintaining the mechanical integrity of the cycled Si material, along with preserving electrical connections.Abstract:
For silicon nanowires (Si NWs) to be used as a successful high capacity lithium-ion battery anode material, improvements in cycling stability are required. Here we show that a conductive polymer surface coating on the Si NWs improves cycling stability; coating with PEDOT causes the capacity retention after 100 charge–discharge cycles to increase from 30% to 80% over bare NWs. The improvement in cycling stability is attributed to the conductive coating maintaining the mechanical integrity of the cycled Si material, along with preserving electrical connections between NWs that would otherwise have become electrically isolated during volume changes.read more
