摘要
水电池中电极/电解质界面不稳定导致的活性材料塌陷和降解是降低容量的主要障碍之一。在这里,我们通过逆转臭名昭著的副反应,包括电极材料的损失和溶解:当我们在氢离子电池中的六氰合铁酸铜电极的电化学循环中应用奥斯特瓦尔德熟化(OR)时,溶解的铜离子和铁离子经历了一个结晶过程,在电极表面形成了一个由交联立方体组成的稳定界面层。该层通过 OR 诱导的电极颗粒生长暴露出低指数晶面(100)和(110),并辅以空位有序的(100)超晶格,从而促进了离子迁移。我们的设计极大地稳定了电极-电解质界面,实现了一百万次循环寿命和 91.6% 的容量保持率,而完整电池在 3000 次循环后的容量保持率为 91.7%。
Collapsing and degradation of active materials caused by the electrode/electrolyte interface instability in aqueous batteries are one of the main obstacles that mitigate the capacity. Herein by reversing the notorious side reactions include the loss and dissolution of electrode materials: as we applied Ostwald ripening (OR) in the electrochemical cycling of a copper hexacyanoferrate electrode in a hydronium-ion batteries, the dissolved Cu and Fe ions undergo a crystallization process that creates a stable interface layer of cross-linked cubes on the electrode surface. The layer exposed the low-index crystal planes (100) and (110) through OR-induced electrode particle growth, supplemented by vacancy-ordered (100) superlattices that facilitated ion migration. Our design stabilized the electrode–electrolyte interface considerably, achieving a cycle life of one million cycles with capacity retention of 91.6%, and a capacity retention of 91.7% after 3000 cycles for a full battery.
