Development and Material Analysis of Lithium Metal Battery

随着人们对锂电池续航要求不断提高,开发新体系的锂电池成为研究的热点。锂金属电池凭借着较高的比能量,吸引着众多的关注。但是由于存在正极材料克容量和稳定性不足、固态电解质材料界面阻抗大以及锂金属负极膨胀等各方面的限制,导致目前锂金属电池距离大规模应用仍有一段距离。本文从常用的正极材料、锂金属负极材料以及固态电解质材料出发,论证分析了各个材料目前的技术进展,并评估了各个材料的发展前景。

With the continuous improvement of lithium battery endurance,the development of new lithium battery system has Attract people's interest.Lithium metal battery has become one of the most popular fields because of its high specific energy.However,there is still a long way before the application of lithium metal batteries due to the limitation of material properties,including the low capacity and stability of cathode,the high resistance of the interface and the swelling of lithium metal.Based on the common cathode materials,lithium metal anode materials and solid electrolyte materials,we discuss and analyze the materials using in lithium metal battery.
