Proton-based battery chemistry starts with the recent discoveries of materials for proton redox reactions and leads to a renaissance of proton batteries. In this article, the historical developments of proton batteries are outlined and key aspects of battery chemistry are reviewed.
Lead electrolysis of PbO 2 /PbSO 4 (PbO 2 + 2e − + SO 4 2− + 4H + ↔ PbSO 4 + 2H 2 O) and PbSO 4 /Pb (PbSO 4 + 2e − ↔ Pb + SO 4 2−) have been extensively developed and are commercially available from lead acid batteries, making them readily accessible for designing novel aqueous proton batteries.
1 lut 2021 · Proton batteries do not compete with nonaqueous batteries in energy density; the salient advantage of proton storage is its rate capability, which is associated with its tiny size and its nature of forming hydrogen bonding.
1 lis 2023 · Here, the authors introduce a hydroxy-silicon proton acceptor as OER catalyst which greatly accelerates the deprotonation process in OER and prolong the cycle life of zinc-ion batteries.
9 wrz 2024 · In this perspective, we comprehensively summarize the current advances in proton-based energy storage based on 2D materials. We begin by providing an overview of proton-based energy storage systems, including proton batteries, pseudocapacitors and electrical double layer capacitors.
21 lis 2021 · Here we introduce a novel aqueous proton full battery that shows remarkable rate capability, cycling stability, and ultralow temperature performance, which is driven by a hydrogen gas anode and a Prussian blue analogue cathode in a concentrated phosphoric acid electrolyte.
14 gru 2023 · Proton battery consists of a proton storage material and proton donor electrolyte. Proton donor electrolytes are usually derived from acidic aqueous solutions (H 2 SO 4, H 3 PO 4, etc), while the protons generated by the reaction of polyvalent ions such as Zn 2+ with the solvent H 2 O in mild electrolytes are usually ignored. For proton battery ...
