Abstract
Anode corrosion in aqueous zinc-ion batteries (AZIBs) leads to electrochemically inert surface and uncontrolled deposition, severely impeding the batteries' lifespan. Efforts to stabilize the zinc anode have primarily focused on modifying external environmental factors, which seldom address the defects inherent to these zinc anodes. Here, we elucidate the relationship between the prevalent dislocation defects in the pristine commercial Zn and their propensity for severe corrosion in aqueous electrolytes. A pressurized recrystallization strategy that fundamentally suppresses the formation of defects is proposed through a dislocation-based creep mechanism. This strategy induces the formation of a nearly single (002) crystal plane-oriented texture and millimeter-scale grains, which homogenizes the surface potential and effectively suppresses galvanic corrosion. As a result, the zinc half-cell stably operates for over 2500 hours at 10 mA cm−2 and the Coulombic efficiency reaches 99.97%. Furthermore, the as-fabricated zinc–iodine full cell retains 96% and 75% of its initial capacity after 5000 and 20 000 cycles at 2 A g−1, respectively. A large-sized pouch cell is also assembled, achieving a reversible capacity of approximate 120 mAh for over 1500 cycles. The proposed facile and efficient pressurized recrystallization strategy addresses the key issue of zinc corrosion and advances the practical applications of AZIBs.
含水锌离子电池(azib)的阳极腐蚀导致表面电化学惰性和不受控制的沉积,严重影响电池的使用寿命。稳定锌阳极的努力主要集中在改变外部环境因素上,很少解决锌阳极固有的缺陷。在这里,我们阐明了原始商业锌中普遍存在的位错缺陷与其在水溶液中严重腐蚀的倾向之间的关系。通过位错蠕变机制,提出了一种从根本上抑制缺陷形成的加压再结晶策略。该策略诱导形成接近单一(002)晶面取向织构和毫米级晶粒,从而均匀化表面电位并有效抑制电偶腐蚀。结果表明,锌半电池在10 mA cm−2下稳定工作2500小时以上,库仑效率达到99.97%。此外,在2a g−1下循环5000次和20000次后,制备的锌碘全电池分别保持了96%和75%的初始容量。还组装了一个大尺寸的袋式电池,实现了大约120毫安时的可逆容量,超过1500次循环。提出的简便高效的加压再结晶策略解决了锌腐蚀的关键问题,促进了azib的实际应用。
