在环境空气中实现能量密集、高度可充电的非水锂氧电池仍然是一个巨大的挑战,因为典型的高容量正极(Li2O2)和负极(锂金属)的活性材料在空气中不稳定。在此,构建了一种新型锂氧全电池,将由聚环氧乙烷(PEO)/磷酸铝钛锂(LATP)/蜡复合层保护的锂阳极与LiOH基阴极耦合。受保护的锂在空气和水中稳定,并且允许在环境空气下的湿非水电解质中进行可逆、无枝晶的锂剥离/电镀。基于 LiOH 的全电池反应不受空气中水分(湿度高达 99%)的影响,并且比 Li2O2 表现出更好的抗 CO2 污染能力,从长远来看,电化学性能更加一致。目前将受保护的锂阳极与 LiOH 基阴极耦合的方法有望开发出能够在环境大气中运行的长寿命、高能量的锂空气电池。通过将 LiOH 基阴极和具有复合保护层的空气稳定锂阳极耦合,成功演示了直接在周围环境中运行的高度可充电锂空气电池。该系统的主要优点包括:1)出色的电化学稳定性; 2)无锂枝晶; 3)优异的耐湿度(99%)和CO2性能; 4)适用于高湿电解液(高达50vol%)。
Realizing an energy‐dense, highly rechargeable nonaqueous lithium–oxygen battery in ambient air remains a big challenge because the active materials of the typical high‐capacity cathode (Li2O2) and anode (Li metal) are unstable in air. Herein, a novel lithium–oxygen full cell coupling a lithium anode protected by a composite layer of polyethylene oxide (PEO)/lithium aluminum titanium phosphate (LATP)/wax to a LiOH‐based cathode is constructed. The protected lithium is stable in air and water, and permits reversible, dendrite‐free lithium stripping/plating in a wet nonaqueous electrolyte under ambient air. The LiOH‐based full cell reaction is immune to moisture (up to 99% humidity) in air and exhibits a much better resistance to CO2 contamination than Li2O2, resulting in a more consistent electrochemistry in the long term. The current approach of coupling a protected lithium anode with a LiOH‐based cathode holds promise for developing a long‐life, high‐energy lithium–air battery capable of operating in the ambient atmosphere. A highly rechargeable lithium‐air battery operating directly in ambient environment is successfully demonstrated by coupling a LiOH‐based cathode and an air‐stable lithium anode with a composite protective layer. Key advantages of the system include: 1) outstanding electrochemical stability; 2) Li dendrite‐free; 3) superior resistance to humidity (99%) and CO2; 4) being applicable to highly wet electrolytes (up to 50vol%).
