Organic Electrode Materials for Dual‐Ion Batteries

Abstract

Organic materials are widely used in various energy storage devices due to their renewable, environmental friendliness and adjustable structure. Dual‐ion batteries (DIBs), which use organic materials as the electrodes, are an attractive alternative to conventional lithium‐ion batteries for sustainable energy storage devices owing to the advantages of low cost, environmental friendliness, and high operating voltage. To date, various organic electrode materials have been applied in DIBs. In this review, we present the development of DIBs with a following brief introduction of characteristics and mechanisms of organic materials. The latest progress in the application of organic materials as anode and cathode materials for DIBs is mainly reviewed. Finally, we also discussed the challenges and prospects of organic electrode materials for DIBs.

Unveiling Organic Electrode Materials in Aqueous Zinc-Ion Batteries: From Structural Design to Electrochemical Performance

“…Organic electrode materials in AZIBs can be classified into n-type, p-type, or bipolar materials according to the redox processes and the type of binding ions (Fig. 1 c) [ 58 , 59 ]. For n-type organics, redox reactions occur between neutral and negatively charged states, initially undergoing a reduction reaction combined with cations [ 59 ].…”

Two p-type ester-linked dihydrophenazine-based polymers as high-performance cathode materials for lithium-ion batteries

“…Organic cathode materials (OCMs) are promising alternatives with high resource abundance, high capacity, and precise structural control, as well as high processability and flexibility. 2–4 In particular, sustainable OCMs are superior as candidates for next-generation green battery technology because of their eco-friendly advantages of low waste generation, low carbon footprint, etc. In addition to the abundant bio-resources generously provided by nature, the voluminous by-products of the chemical industry also provide OCMs with almost cost-free and sufficient sources.…”
