The rise of aqueous rechargeable batteries with organic electrode materials

Abstract

<p>This review provides timely access to state-of-the-art advances of organic electrode materials in aqueous rechargeable batteries.</p>

Proton-assisted calcium-ion storage in aromatic organic molecular crystal with coplanar stacked structure

“…Moreover, organic materials show the merits of high abundance, high electrochemical reactivity, and large structural diversity. Thus, they are promising candidate electrodes for electrochemical energy storage applications 20 – 22 . Unfortunately, little attention has been given to the exploration of Ca 2+ -hosting organic electrodes, and reports of their performance is very limited 23 – 26 .…”

Emerging trends in sustainable battery chemistries

“…Ideal candidates include batteries using organic electrodes (e.g., naphthalene diimide, phosphaviologens, quinone), which are fully biodegradable and environmentally benign [59,60]. Aqueous based electrolytes should also be adopted to avoid hazardous organic solvent exposure to the environment during disposal [61,62]. Unfortunately, research into organic batteries remains in its infancy and major challenges with organic batteries are that most of them operate at lower cell voltages (<3 V) and with limited specific capacities (<250 mAh/g), limiting their energy densities [61,62].…”

Cracked bark-inspired ternary metallic sulfide (NiCoMnS4) nanostructure on carbon cloth for high-performance aqueous asymmetric supercapacitors

“…Electrochemical energy storage is one of the most commonly used energy-storage technologies available today. Lithium-ion (Li + ) batteries occupy a large proportion of the energy-storage market and are extensively used in electric vehicles and mobile electronic devices, such as cell phones, laptops, and digital cameras, on account of their high energy density, operating voltage, and safety and long lifetime [1][2][3][4][5][6][7][8]. However, the relatively low power density and limited and uneven distribution of Li resources are the main bottlenecks associated with Li + batteries [9,10].…”
