Abstract
Abstract Lithium‐ion batteries are part of modern life, being present in daily‐used objects such as mobile phones, tablets, computers, watches, sport accessories, electric scooters, and cars. The next‐generation batteries require the development of innovative polymers that help to improve their performance in terms of power density, cyclability, raw materials' availability, low weight, printability, flexibility, sustainability, or security. This article highlights recent developments in the area of redox‐active, electronic/ionic conducting polymers. This includes the development of innovative binders for electrodes, polymer electrolytes, and redox polymers. All these new polymer developments are leading to new battery technologies such as metal–polymer batteries, organic batteries, polymer–air, and redox–flow batteries, which are expected to complement the current lithium‐ion technologies in the future.
