【摘要】：随着化石燃料的逐渐消耗和城市环境污染的日益严重,纯电动和混合动力汽车的开发使用越来越受到人们的重视.受到锂离子电池能量密度的限制,目前电动汽车的连续行驶距离仍远低于内燃机动力汽车.作为新一代电动车供能设备,基于有机电解液的锂空气电池由于结构相对简单,理论能量密度极高,成本低廉,已成为学术界的研究热点.本文从反应机理、电解液、空气电极以及金属锂负极等四个方面入手,详细介绍了近年来锂空气电池的重要研究进展以及在基础研究方面存在的科学问题,指出了该体系面临的挑战和今后的重要研究方向.
[Abstract]:With the gradual consumption of fossil fuels and the increasing pollution of urban environment, people pay more and more attention to the development and use of pure electric and hybrid electric vehicles. Limited by the energy density of lithium-ion battery, the continuous driving distance of electric vehicle is still far lower than that of internal combustion engine. As a new generation of electric vehicle energy supply equipment, lithium-air battery based on organic electrolyte has become a research hotspot in academia because of its relatively simple structure, high theoretical energy density and low cost. In this paper, from four aspects of reaction mechanism, electrolyte, air electrode and metal lithium negative electrode, the important research progress of lithium air battery in recent years and the scientific problems existing in basic research are introduced in detail. The challenges faced by the system and the important research directions in the future are pointed out.
