We reviewed the progress and challenges in the rational design and use of halogen storage electrode materials for rechargeable batteries, which included HIBs such as FIBs, CIBs, and BIBs, based on a halide-ion shuttle and DIBs that consisted of halogen storage cathodes and cation storage anodes.
This review presents a new insight by summarizing the advances in structure and property optimizations of battery electrode materials for high-efficiency energy storage. In-depth understanding, efficient optimization strategies, and advanced techniques on electrode materials are also highlighted.
See all authors Porous electrodes are critical in determining the power density and energy efficiency of redox flow batteries. These electrodes serve as platforms for mesoscopic flow, microscopic ion diffusion, and interfacial electrochemical reactions.
Organic solid electrode materials are promising for new generation batteries. A large variety of small molecule and polymeric organic electrode materials exist. Modelling and characterization techniques provide insight into charge and discharge. Several examples for all-organic battery cells have been reported to date.
Since p-type materials are naturally characterized by a high redox potential, finding those suitable to act in negative electrodes for the assembly of an anion-ion battery can be difficult. One specific backbone stands out: the 4,4-bipyridinium one, also known as viologen (Fig. 4 n), because of its low redox potential .
