电动汽车产业中两种锂离子电池主流地位之争

The Contention for Mainstream Status of the Two Kinds of Lithium Ion Battery in Electric Automobile Industry

随着能源和环境危机问题的日益突出，近年来，各国政府大力推动电动汽车和储能产业的发展。锂离子电池由于自身特点而成为其不错的选择，尤其是基于锰酸锂和磷酸铁锂的电池。关于它们中哪一个占据主流地位的问题有着激烈的争论。本文从它们的结构、物理性能、化学性能等方面详细分析了各自的优缺点，并对比了二者在储能、电动汽车动力方面应用的优势和现状。最后得出的结论是：目前锰酸锂电池更适合电动汽车领域的应用，而磷酸铁锂电池则是储能领域的主流选择。

With the energy and environmental crisis has become increasingly prominent, in recent years, governments of various countries energetically have：promoted the developments of the industries of electric automobile and stored energy, the lithium ion battery has become their good choice due to its own features, above all, for the batteries which are made from LiMn204 and LiFePO4. There is a violent controversy concerning the question what which occupying the mainstream status among them. In this paper, the author analyzes in detail their respective merits and demerits in the respects of structures, physi-cal and chemical properties and so on, and compares the superiorities and current situations of these two kinds in the applica-tions for energy storage and electric auto-mobile power. Finally, the conclusion is obtained, in which LiMn204 battery is be-lieved to be more suitable for the application of electric vehicle field, while LiFePO4 battery is considered as the mainstream choice for energy storage area.
