Abstract Hydronium-ion batteries are regarded as one of the most promising energy technologies next-generation power sources, benefiting from their cost effectivity and sustainability merits. Herein, we propose a hydronium-ion battery which is based on an organic pyrene-4,5,9,10-tetraone anode inorganic MnO 2 @graphite felt cathode in acid electrolyte. Its operation involves quinone/hydroquinone redox reaction /Mn 2+ conversion cathode, parallel with transfer H 3 O + between two electrodes....
Zn–organic batteries are attracting extensive attention, but their energy density is limited by the low capacity (<400 mAh g–1) and potential (<1 V vs Zn/Zn2+) of organic cathodes. Herein, we propose a long-life high-rate battery that includes poly(1,5-naphthalenediamine) cathode Zn anode in an alkaline electrolyte, where reaction based on coordination between K+ C═N group (i.e., C═N/C–N–K conversion). Interestingly, find discharged can recover to its initial state quickly with presence O2,...
Most rechargeable batteries suffer from severe capacity loss at low temperature, which limits their applications in cold environments. Herein, we propose an original proton battery, involves a MnO2@graphite felt cathode and MoO3 anode acid electrolyte containing Mn2+. Its operation depends on the MnO2/Mn2+ conversion H3O+ insertion/extraction anode. This battery exhibits promising energy density (177.4 Wh kg–1) supercapacitor-like power (66.6 kW room temperature. We demonstrate that shows...
Aqueous Zn-organic batteries have received considerable attention owing to their green, low-cost and high safe nature. Unfortunately, organic materials generally exhibit insulator nature (≈10-10 S cm-1 ), most of reported promising performances are achieved with a low mass-loading (≈2 mg cm-2 ) in cathode, which is far away from practical application (10 ). Herein, we demonstrate semi-conductive polymer poly(1,8-diaminonaphthalene) (PDAN) cathode material for Zn batteries, shows moderate...
Ammonium-ion batteries are promising solutions for large-scale energy storage systems owing to their cost-effectiveness, safety, and sustainability. Herein, we propose an aqueous ammonium-ion battery based on organic poly(1,5-naphthalenediamine) anode inorganic Prussian blue cathode in 19 M (M: mol kg−1) CH3COONH4 electrolyte. Its operation involves a reversible coordination reaction (C=N/C–N– conversion) the NH4+ insertion/extraction cathode, along with acting as charge carrier...
ConspectusLithium ion batteries (LIBs) with inorganic intercalation compounds as electrode active materials have become an indispensable part of human life. However, the rapid increase in their annual production raises concerns about limited mineral reserves and related environmental issues. Therefore, organic (OEMs) for rechargeable once again come into focus researchers because design flexibility, sustainability, compatibility. Compared conventional cathode Li batteries, OEMs possess some...
The flexible utilization of renewables for power-to-fuel and/or power-to-power is enabled by the decoupled amphoteric water electrolysis and Mn–Zn battery.
The nonmetallic charge carrier hydronium (H3O+) possesses the advantages of cost-efficiency and high ionic conductivity. However, only several available electrode materials have been reported for reversibly storing H3O+, most them suffer from limited cycle life due to soluble and/or structurally unstable nature. Herein, we demonstrate that an organic quinone dibenzo[b,i]thianthrene-5,7,12,14-tetraone (DTT) exhibits capability accommodate H3O+ in acid electrolyte, with a capacity 212 mAh...

Sodium‐ion batteries (SIBs) suffer from sluggish kinetics, large volume change, and limited specific capacity due to the radius of Na+. These issues can be solved through using covalent organic frameworks (COFs) as electrodes.
