Abstract

Abstract: Batteries have become an integral part of everyday life—from small coin cells to batteries for mobile phones, as well as batteries for electric vehicles and an increasing number of stationary energy storage applications. There is a large variety of standardized battery sizes (e.g., the familiar AA‐battery or AAA‐battery). Interestingly, all these battery systems are based on a huge number of different cell chemistries depending on the application and the corresponding requirements. There is not one single battery type fulfilling all demands for all imaginable applications. One battery class that has been gaining significant interest in recent years is polymer‐based batteries. These batteries utilize organic materials as the active parts within the electrodes without utilizing metals (and their compounds) as the redox‐active materials. Such polymer‐based batteries feature a number of interesting properties, like high power densities and flexible batteries fabrication, among many more. Abstract : The utilization of polymeric active materials within batteries enables the design and fabrication of flexible and thin energy storage systems. Moreover, these batteries can also feature very high power densities allowing charging/discharging within a few seconds to minutes. The properties of the utilized redox polymers can be tuned by the molecular structure.
