基于专利分析的我国电动汽车电池技术发展趋势研究

Electric Vehicle Battery Technology Development Trend in China Based on Patent Analysis

以电动汽车电池技术专利的申请数据为基础,从专利所有地、专利类型、专利所有者等方面进行了分析。研究结果表明,(1)目前国内的电池技术还处于基础创新初期;(2)锂离子电池性能优良,是目前电动汽车主流的电池技术,也是未来主要的发展方向;(3)结合国内的新能源汽车政策以及专利的申请数量时间序列,发现政策出台对技术创新的推动有很大的作用。

Based on application data of electric vehicle battery technology patent , this paper analyzes the patent distribu- tion across provinces, patent type, and patent ownership. The results indicate that： （1） current battery technology is still in the early stage of technological innovation by classification study; （2） lithium - ion batteries will become the mainstream and the future direction of the electric vehicle battery technology because of good performance; （3） the comparison between the patent quantity and launch of national policies indicates that policies have a great influence to promote technological in- novation.
