Silicon is a most promising next generation lithium ion battery electrode material but it suffers poor cyclability due to the volume expansion that results in loss of electrical contact and unstable SEI.
This Si composite product is made by encapsulating nano-Si particles in the 3D cross-linked conductive polymer framework. It not only allows fast electrical and ionic transport, but also provides free space to allow giant volume expansion. This Si composite provides a ready-to-use electrochemically active nano-Si anode that would increase the capacity of conventional lithium ion battery, and improve the cycle-life performance of Si-based anodes.

This study develops a tunable 3D nanostructured conductive gel framework as both binder and conductive framework for lithium ion batteries. A 3D nanostructured gel framework with continuous electron pathways can provide hierarchical pores for ion transport and form uniform coatings

Silicon has a high-specific capacity as an anode material for Li-ion batteries, and much research has been focused on overcoming the poor cycling stability issue associated with its large volume changes during charging and discharging processes, mostly through nanostructured material

Nanostructured materials are critically important in many areas of technology because of their unusual physical/chemical properties due to confined dimensions. Owing to their intrinsic hierarchical micro-/nanostructures, unique chemical/physical properties, and tailorable functionalities, hydrogels and their derivatives have emerged as an
