摘要
锂离子电池的成功商业化,起始于石油焦负极材料。负极作为锂离子电池必不可少的关键材料,目前主要集中在碳、钛酸锂以及硅基等合金类负极,采用传统的碳负极可以基本满足消费电子、动力电池、储能电池的要求,采用钛酸锂可以满足高功率密度、长循环寿命的要求,采用合金类负极材料有望进一步提高能量密度。本文小结了目前广泛使用和正在研究的锂离子电池负极材料的性能特点,讨论了下一代锂离子电池负极材料的研究和发展状况。
Successful commercialization of lithium ion batteries originated from the development of petroleum coke based anode materials by SONY in 1991. Anode materials play a key role in the progress of lithium ion batteries. Up to now, carbon, lithium titanate and alloy anode materials have been commercialized. Li-ion batteries using conventional carbon anode materials can more or less meet the requirements of consumer electronics, electric vehicles and large scale energy storage applications. Lithium titanate anodes can meet high power density applications such as electric buses, whereas the use of alloy anodes can further improve the energy density of Li-ion batteries. In this paper, we summarize briefly the characteristics of anode materials that have been commercialized and widely used, and discuss developments of next generation anode materials.
