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.
