Mapping the trends and prospects of battery cathode materials based on patent landscape

Frontiers in Energy 2023年第6期17卷 822-832页

作者： Chen YANG Xin-Yu MU School of Japanese Culture and Economy Xi’an International Studies UniversityXi’an 710128China The Northeast Asian Research Center Xi’an International Studies UniversityXi’an 710128China

Advancing portable electronics and electric vehicles is heavily dependent on the cutting-edge lithium-ion (Li-ion) battery technology, which is closely linked to the properties of cathode materials. Identifying trends and prospects of cathode materials based on patent analysis is considered a kernel to optimize and refine battery related markets. In this paper, a patent analysis is performed on 6 popular cathode materials by comprehensively considering performance comparison, development trend, annual installed capacity, technology life cycle, and distribution among regions and patent assignees. In the technology life cycle, the cathode materials majorly used in electric vehicle have entered maturity stage, while the lithium cobalt oxide (LCO) cathode that is widely used in portable electronics is still in the growth stage. In global patent distributions, China holds more than 50% of total patents. In the top 10 patent assignees of 6 cathode materials, 2 institutes are from China with the rest being Japan (6) and Republic of Korea (2), indicating that the technology of cathode materials in China is relatively scattered while cathode research is highly concentrated in Japan and Republic of Korea. Moreover, the patent distribution has to consider practical issues as well as the impacts of core patents. For example, the high cost discourages the intention of applying international patents. This paper is expected to stimulate battery research, understand technical layout of various countries, and probably forecast innovative technology breakthroughs.

基于我国1950-2020年新一代人工智能技术的专利数据，通过构建计量经济模型，分析了中国创新情境下基础研究影响不同属性类别关键核心技术创新的异质性机理、周期性效应和传导路径。结果表明：总体来看，基础研究对人工智能关键核心技术创新的促进作用显著，但是对不同类型特征和技术属性的人工智能关键核心技术创新的影响存在一定的异质性。例如，对跨媒体分析推理、脑机接口、自然语言处理和智能芯片这类知识密集型的技术创新的促进作用比较显著，而对智适应学习和自主无人系统这类知识复杂型技术的促进作用并未通过实证检验。从技术生命周期来看，基础研究对关键核心技术创新的影响存在明显的阶段性特征，且呈“U型”分布。其中，对萌芽期Ⅰ、成长期Ⅱ、萌芽期Ⅱ这三个阶段进程中的关键核心技术创新促进作用更为显著，而对成长期Ⅰ、成熟期Ⅰ和衰退期Ⅰ的作用并不显著。最后，从构建基础研究、应用基础研究和关键核心技术创新体系等方面提出了相关政策建议。
