锂离子电池正极材料--高能量密度锂离子电池材料研究进展

Cathode Materials for Lithium Ion Batteries (LIBs): A Review on Materials related aspects towards High Energy Density LIBs

Ambesh Dixit

摘要:

本文综述了自20世纪80年代初钴酸锂问世以来,锂离子二次电池正极材料的发展。随着时间的推移,许多阴极材料被设计和开发,以实现不仅提高容量,而且同时提高功率密度。然而,存在许多挑战,例如阴极材料的循环稳定性、它们的结构和热稳定性、更高的操作电压以及高离子和电子电导率,以在充电和放电期间有效地传输离子和电荷。本文将按时间顺序对锂离子正极材料的发展进行分类,分为不同代。三元氧化物如LiTMOx(TM=过渡金属)被认为是第一代材料,而改性的三元和四元氧化物体系被认为是第二代材料。目前的第三代包括具有更高锂含量的复合氧化物体系,例如旨在获得更高能量密度的Li 2 TMSiO 4。此外,发展正朝向具有非常高的能量密度的可能性的基于锂金属的电池。

英文摘要:

This article reviews the development of cathode materials for secondary lithium ion batteries since its inception with the introduction of lithium cobalt oxide in early 1980s. The time has passed and numerous cathode materials are designed and developed to realize not only the enhanced capacity but also the power density simultaneously. However, there are numerous challenges such as the cyclic stability of cathode materials, their structural and thermal stability, higher operating voltage together with high ionic and electronic conductivity for efficient ion and charge transport during charging and discharging. This article will cover the development of materials in chronological order classifying as the lithium ion cathode materials in different generations. The ternary oxides such as LiTMOx (TM=Transition Metal) are considered as the first generation materials, whereas modified ternary and quaternary oxide systems are considered as the second generation materials. The current i.e. third generation includes complex oxide systems with higher lithium content such as Li2TMSiO4 aiming for higher energy density. Further, developments are heading towards lithium metal based batteries with a possibility for very high energy densities.
