摘要:

非水溶剂Li-O2电池因其高的理论能量密度,近年来备受关注.非水溶剂Li-O2电池的典型结构为金属锂负极、含Li+的非水溶剂电解液和多孔氧气正极.目前,多数Li-O2电池研究集中在正极的氧气电极反应;金属锂负极极强的还原性导致的副反应使Li-O2电池中的化学和电化学反应变得更为复杂.因为,电解液和从正极扩散来的O2都会与金属锂发生反应;锂负极上生成的副反应产物同样会扩散到正极一侧,干扰正极的O2反应.此外,锂负极上可能生成锂枝晶,降低电池的安全性能,进而阻碍Li-O2电池的实用化.因此,研究并解决锂负极的电化学稳定性和安全问题迫在眉睫.本文综述了近年来国内外在非水溶剂Li-O2电池锂负极保护和修饰方面的最新研究进展,包括:可替代的对/参比电极的选择、电解液和添加剂、复合保护层与隔膜的研究、先进实验技术的开发与应用、并针对未来非水溶剂Li-O2电池的发展进行了展望.

Abstract:

The aprotic Li-O2 battery has attracted considerable interest in recent years because of its high theoretical specific energy that is far greater than that achievable with state-of-the-art Li-ion technologies. To date, most Li-O2 studies, based on a cell configuration with a Li metal anode, aprotic Li+ electrolyte and porous O2 cathode, have focused on O2 reactions at the cathode. However, these reactions might be complicated by the use of Li metal anode. This is because both the electrolyte and O2 (from cathode) can react with the Li metal and some parasitic products could cross over to the cathode and interfere with the O2 reactions occurring therein. In addition, the possibility of dendrite formation on the Li anode, during its multiple plating/stripping cycles, raises serious safety concerns that impede the realization of practical Li-O2 cells. Therefore, solutions to these issues are urgently needed to achieve a reversible and safety Li anode. This review summarizes recent advances in this field and strategies for achieving high performance Li anode for use in aprotic Li-O2 batteries. Topics include alternative counter/reference electrodes, electrolytes and additives, composite protection layers and separators, and advanced experimental techniques for studying the Li anode|electrolyte interface. Future developments in relation to Li anode for aprotic Li-O2 batteries are also discussed.

Key words: Lithium-oxygen battery, Lithium metal anode, Li anode stability, Solid electrolyte interphase layer
