Pan Feng's research group of Shenzhen Research Institute has made systematic progress in the research field of silicon-based anode conductive binder for lithium batteries

Lithium-ion batteries have achieved industrial mass production and are widely used in popular industries such as portable electronic devices and electric vehicles.

Binders build stable conductive networks in electrodes

Based on the systematic research progress made by Pan Feng's group on silicon-based anode conductive binders for lithium batteries (Nano Energy2017, 36, 206; ACS Appl.

This important innovation divides the strategies of conducting polymer binders to maintain a stable conductive network of silicon anodes into two categories: (1) Protect the primary conductive network and improve the mechanical stability of the entire electrode

Conductive networks in silicon-based anodes for lithium-ion batteries

Based on the idea of ​​structural chemistry and material genes of lithium batteries, the research group divided the functional groups in the molecular structure of the binder into two categories—mechanical structural elements and conductive structural elements
