下一代电动车用高比能量电池展望

A Prospect over the Developing of High Energy Batteries for Electric Vehicles

新能源汽车是汽车发展的必然方向和关键节点,为应对传统汽车巡航能力上的巨大挑战,开发相应匹配的节能、高效供电体系,是电动车开发的重要环节和关键技术。当前高比能量储能电池研究快速发展,如高镍三元电池、燃料电池、锂-硫/空气电池等以显著的能量优势获得业界普遍关注。新一代能源体系既有瞩目的优点,也存在影响工业化进程的固有问题,这是未来利益与实际情况的相互博弈。文章将基于各类动力电池实用化的角度,对体系的基本情况、应用进展、工业化问题的现状与研究进行介绍。

New energy vehicles are the inevitable direction and key node of automobile development.In order to cope with the huge challenge in the cruising ability of traditional cars,a new energy-saving and efficient power supply systems will be urgently developed,which is an important part and key technology for electric vehicle production.Recently,high energy storage batteries have developed rapidly and been widely investigated by global scholars,for instance,Ni-rich ternary batteries,fuel cells,lithium sulfur batteries,lithium air batteries and so on.However,The new generation energy systems have both the obvious advantages and the difficult problems that affect the industrialization process,considered that their future depends on a competition between the future interests and the actual situations.In this review,based on the angle of benefit in the industrialization,the basic situation,the new application outlook,the current industrialized state industrializa-tion problems are prospected.
