Enable Superior Performance of Solvent-Free Electrode With Ultra-High Loading Through Designed Conductive Binder.

Compared to the traditional slurry-coating process, the solvent-free manufacturing process holds significant potential due to its advantages, including economic viability, thick electrodes, and avoidance of organic solvents. However, the currently dominant solvent-free process suffers from poor mechanical properties and electrochemical instability. Herein, a conductive binder (M@EP), composed of multi-walled carbon nanotubes (MWNT) and epoxy resin-based binders (EP), is designed and synthesized.

Conducting Composite Polymer-Based Solid-State Electrolyte with High Ion Conductivity via Amorphous Condensed Structure and Multiple Li Transport Channels.

Traditional PEO electrolyte has high crystallinity which hinders the transmission of Li, resulting in poor ion conductivity and complicated processing technology. Herein, a polymer electrolyte (p-electrolyte) with a wide electrochemical window and high ionic conductivity is designed, which possesses an amorphous condensed structure. The amorphous structure provides fast transport channels for Li, so the p-electrolyte possesses an electrochemical window of 4.
