A rocking-chair aqueous proton battery is assembled by using dipyridophenazine and indium hexacyanoferrate as the anode and cathode materials, respectively. The reversible amination of redox-active phenazine moieties in dipyridophenazine and fast intercalation–deintercalation of protons in hexacyanoferrate enable the aqueous proton battery to achieve a reversible specific capacity of 37 mA h g?1 at 1 A g?1, good cycling stability with 76.1% capacity retention over 3000 cycles and excellent rate capability.
我院曹劍瑜-許娟團(tuán)隊(duì)最近在Chemical Communications上發(fā)表研究論文(DOI: 10.1039/d1cc01486b)。水系可充電電池通常以金屬離子為電荷載體。然而，金屬元素要么儲(chǔ)量有限，要么開(kāi)采成本相對(duì)較高。在所有離子中質(zhì)子(氫離子)是最輕和最小的，在水溶液中具有最快的遷移速率，而且在地球上資源豐富。本論文設(shè)計(jì)了一種基于有機(jī)陽(yáng)極和無(wú)機(jī)配合物陰極的水系可充電質(zhì)子電池。陽(yáng)極二吡啶吩嗪中氧化還原活性吡嗪?jiǎn)卧目赡姘坊完帢O銦普魯士藍(lán)中質(zhì)子的快速嵌入-脫嵌使該電池在1 Ag -1下可實(shí)現(xiàn)37 mAhg -1的可逆比容量，并展示了良好循環(huán)穩(wěn)定性和出色的倍率性能。此項(xiàng)研究得到了國(guó)家自然科學(xué)基金和江蘇省綠色催化重點(diǎn)實(shí)驗(yàn)室科學(xué)基金的資助。
