电极材料的结构和性能决定了锂电池的输出电压、比容量和循环寿命,传统的电极材料由于其理论比容量受限,已不能满足当前高比特性锂电池的市场需求,因此开发高功率电极材料是未来高比特性锂电池主要的发展方向,这将成为国内外锂电池研究的重点。针对锂电池高功率电极材料的专利申请趋势进行了分析,梳理出锂电池高功率电极材料专利申请的地域分布和全球主要专利申请人,通过对主要专利申请人的专利布局进行分析,指导相关研究单位有效进行专利布局,避免产生专利纠纷,降低研发过程中的专利侵权风险;同时通过技术发展路线寻求重点研发方向的技术创新。

The structure and performance of electrode materials determine the output voltage,specific capacity and cycle life of lithium batteries.Due to their limited theoretical specific capacity,traditional electrode materials can no longer meet the current market demand for high-rate lithium batteries.Therefore,high-power electrodes are developed.Materials are the main development direction of high-rate lithium batteries in the future and will become the focus of research on lithium batteries all over the world.According to the trend and analysis of patent applications for lithium battery high-power electrode materials,the geographical distribution of patent applications for lithium battery high-power electrode materials and major patent applicants in the world were sorted out,and analyzed the patent layout of major patent applicants to guide relevant research units effectively to avoid patent disputes by carrying out patent layout and to reduce the risk of patent infringement in the research and development process.At the same time,technological innovation in key research and development directions was sought through technological development routes.
