Polymer Binders for the Electrodes of Lithium Batteries Part 1. Polyvinylidene Fluoride, its Derivatives and other Commercialized Materials

Abstract

The current situation in technology and developments in the field of polymer binders for composite electrodes of lithium electrochemical systems are discussed. A wide range of synthetic and natural polymers used for this purpose is considered. Emphasis is placed on commercially available materials, which form aqueous solutions or dispersions. The advantages of multifunctional polymer binders are demonstrated. The need for individual selection of a binder for a given active material to achieve and maintain high capacitive and power characteristics of the batteries, as well as to ensure their longterm safe cycling, is shown.

Improving the Adhesion of Multi-Walled Carbon Nanotubes to Titanium by Irradiating the Interface with He+ Ions: Atomic Force Microscopy and X-ray Photoelectron Spectroscopy Study

“…Currently, researchers are trying to solve this problem by adding polymer binders during the preparation of the electrode material, such as polyvinylidene fluoride (PVDF), carboxymethylcellulose (CMC), styrene-butadiene latex (SBL), etc. [5][6][7]. However, this Nanomaterials 2024, 14, 699 2 of 12 approach is accompanied by a significant decrease in the conductivity of the electrode material, which creates a need to develop new binder compositions and other methods for increasing the adhesion of the electrode to the substrate.…”
