Three-dimensionally cross-linked polypyrrole (3D cross-linked polypyrrole) is a conductive powder made by crosslinking polypyrrole with a dopant molecule - phytic acid. It can form intrinsically conductive hydrogels with a hierarchically porous microstructure. Its porosity promotes transport of electrons and facilitates the diffusion of ions and other small molecules. Its flexibility can also help accommodate the strain caused by volume change during electrochemical cycling. Together with the advantage of high surface area, and biocompatibility, this material provides the feasibility for fabricating flexible, lightweight, energy and bioelectronic devices. Three-dimensionally cross-linked polypyrrole can also been derived into porous carbon nanomaterials via post thermal treatment and activation. The resulted carbon matrix has maintained the hierarchical nanostructure of 3D cross-linked polypyrrole and has been demonstrated as an effective additive to improve energy storage and conversion performance of other electrochemically active materials.

Silicon is considered one of the most promising anode materials for high-performance Li-ion batteries due to its 4200 mAh/g theoretical specific capacity, relative abundance, low cost, and environmental benignity. However, silicon experiences a dramatic volume change (∼300%) during full charge/discharge
