High-performance silicon anode

Description

• Application: 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.[1]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 [1] increase the capacity of conventional lithium ion battery, and [2] improve the cycle-life performance of Si-based anodes.[2][3][4][5][6]
