Abstract
We design a carbon-free Si/polyaniline hybrid anode composed of porous Si dendrites and oxalic acid doped polyaniline coatings. Such a 3D conductive porous structure offers the feasibility to facilitate the transport of electrons/ions and simultaneously alleviate the volume expansion of the silicon anode.
