新能源汽车这些年来在技术的角度,应该说取得了一系列进展。锂离子动力电池为代表的电动汽车核心技术取得重大突破。中国动力电池的技术发展经过了三个阶段“:十五”是锰酸锂电池,“十一五”是磷酸铁锂电池,“十二五”是三元电池,“十三五”是高比能量的新一代的锂离子动力电池。系统的比能量在逐年的提升,系统的成本在逐年的下降,我们预计到2020年还会在成本方面到达1元/瓦时这么一个目标。中国的 New energy vehicles over the years from a technical point of view, it should be said that made a series of progress. Lithium-ion battery as the representative of the core technology of electric vehicles made a major breakthrough. China power battery technology development through three stages “: fifteen ” is a lithium manganese oxide battery, “eleven five ” is lithium iron phosphate battery, “second five ” is a ternary battery “Thirteen Five” is a new generation of high-energy lithium-ion battery. The specific energy of the system is increasing year by year. The cost of the system is declining year by year. We expect to achieve the target of 1 yuan / W in terms of cost by 2020. China’s
