全球富锂层状氧化物专利分析

Global patent analysis of Li-rich layered oxides

富锂层状氧化物(Li-rich layered oxides,LRLOs)具有能量密度高、成本低等特点,被广泛认为是最具发展潜力的锂离子电池正极材料之一。世界诸多国家在LRLOs领域深耕多年,申请了许多具有重要意义的专利。本文通过智慧芽(PatSnap)全球专利信息数据库对全球已公开的LRLOs相关专利进行检索,对获得的1647项专利,按照申请情况、地域分布、申请人与发明人、技术类型等进行了系统整理和深入分析。结果表明:LRLOs正处于高速发展期,具有广阔的发展前景及商业价值。然而,LRLOs仍存许多亟待解决的技术难题,尤其是容量及电压衰减问题。为了实现LRLOs的广泛商业化应用,需加大创新力度,针对LRLOs面临的主要问题,对材料进行不断优化及改进。本文对今后LRLOs的研发及产业布局具有重要参考价值。

Lithium rich layered oxides(LRLOs)are widely regarded as one of the most promising cathode materials for lithium-ion batteries due to their high energy density and low cost.Many countries worldwide have been deeply engaged in LRLO research for years,resulting in numerous significant patent applications.This paper utilized the PatSnap global patent information database to search for publicly available LRLO-related patents on a global scale,systematically organizing and analyzing 1647 patents based on their application status,geographical distribution,applicants and inventors,technology types,and more.The findings suggest that LRLOs are experiencing rapid development with broad prospects and commercial value.The results indicate that LRLOs are in a period of rapid development and have broad development prospects and commercial value.Nevertheless,LRLOs still encounter pressing technical challenges,particularly concerning capacity and voltage attenuation issues.In order to achieve large-scale commercialization of LRLOs,it is still necessary to increase innovation efforts and continuously optimize and improve materials to address the main problems faced by LRLOs.This paper holds significant reference value for guiding future research and industrial positioning related to LRLOs.
