Review on the Binders for Sustainable High‐Energy‐Density Lithium Ion Batteries: Status, Solutions, and Prospects

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(45)

Published: July 5, 2023

Abstract The upsurging demand for electric vehicles and the rapid consumption of lithium‐ion batteries (LIBs) calls LIBs to possess high energy density resource sustainability. former requires usage electroactive materials with capacity maximum amount within fixed electrode volume. latter essentially creates a closed‐loop circulation scenario materials. In all aspects, binders are practical significance in bonding materials, maintaining integrity detaching slurry from current collector. Currently, key role enhancing electrochemical behavior sustainable high‐capacity has been recognized. Meanwhile, that designed easy cost‐effective recycling gradually reported. Herein, recently developed hold promises establishing high‐energy‐density summarized. binder facilitating separation first highlighted. Subsequently, special attention is paid conductive binders, contributing less battery chemistries higher electrode. Additionally, progress emerging also reviewed. It believed advances will open up opportunities economy.

Challenges in Recycling Spent Lithium‐Ion Batteries: Spotlight on Polyvinylidene Fluoride Removal

Global Challenges, Journal Year: 2023, Volume and Issue: 7(3)

Published: Feb. 5, 2023

Abstract In the recycling of retired lithium‐ion batteries (LIBs), cathode materials containing valuable metals should be first separated from current collector aluminum foil to decrease difficulty and complexity in subsequent metal extraction. However, strong binding force organic binder polyvinylidene fluoride (PVDF) prevents effective separation Al foil, thus affecting recycling. This paper reviews composition, property, function, mechanism PVDF, elaborates on technologies material (e.g., physical separation, solid‐phase thermochemistry, solution chemistry, solvent chemistry) as well corresponding reaction behavior transformation mechanisms PVDF. Due characteristic variation systems, dissolution, swelling, melting, degradation processes PVDF exhibit considerable differences, posing new challenges efficient spent LIBs worldwide. It is critical separate recycle reduce environmental risks recovery resources. Developing fluorine‐free alternative solid‐state electrolytes a potential way mitigate pollution EV era.
