锂离子电池用卤化物固态电解质:专利情形分析(2024年)Halide Solid Electrolytes for Li-ion Batteries Patent Landscape Analysis 2024 |
本报告分析了与锂离子电池用卤化物固体电解质相关的专利申请和出版物的趋势,并研究了专利出版物数量(依国家和专利持有人)、依细分市场划分的主要专利持有人和新进者的趋势。专利等)等我们将向您发送一份 Excel 文件,其中总结了要分析的专利(总共超过 330 项)。
近几十年来,固态锂离子电池由于其安全性和高能量密度潜力的显着优势而引起了广泛的关注。具有快速离子传输和优异稳定性的固态电解质(SE)对于这种有前途的下一代锂电池的商业化至关重要。因此,对无机固体电解质如硫化物电解质和氧化物电解质的研究已经积极进行。然而,两者都未能实现电导率和稳定性之间的最佳平衡。氧化物的晶界阻抗高,硫化物的稳定性低。然而,卤化物基固体电解质具有室温离子电导率(>10-3 S.cm-1)、与氧化物正极材料良好的相容性以及优异的化学稳定性和可扩展性,因此被认为是其中之一。
对卤化物固体电解质日益增长的兴趣也透过监测固态锂离子电池相关专利得到证实。截至2023年9月,已公开与锂离子电池卤化物固态电解质材料相关的专利330余项。对于从事固态电池行业的公司来说,现在至关重要的是从技术、竞争和智慧财产权 (IP) 的角度审查这些新兴材料。

Solid-state Li-ion batteries have garnered significant attention in recent decades due to their notable advantages of safety and potential for high energy density. Solid electrolytes (SE) with rapid ionic transport and excellent stability are essential for the commercialization of this promising next-generation of Lithium batteries. Hence, there has been extensive exploration of inorganic solid electrolytes, including sulfide- and oxide-based electrolytes. Unfortunately, both have been unable to strike an optimal balance between conductivity and stability. Oxides suffer from high impedance of grain boundaries, while sulfides experience poor stability. However, halide-based solid electrolytes are increasingly being recognized as one of the most promising options for solid-state Li-ion batteries, owing to their decent room temperature ionic conductivity (>10-3 S.cm-1), good compatibility with oxide cathode materials, excellent chemical stability, and scalability.
The increasing interest in halide solid electrolytes has been observed while monitoring patents on solid-state Li-ion batteries. As of September 2023, over 330 patent families have been published on halide solid electrolyte materials for Li-ion batteries. It is now crucial for companies operating in the solid-state battery industry to closely examine these emerging materials from technological, competitive, and intellectual property (IP) perspectives.
In this context, Knowmade is releasing a new patent landscape report that focuses on halide solid electrolyte materials for Li-ion batteries. In this report, Knowmade's analysts have selected and analyzed over 860 patents and patent applications from more than 330 patent families (inventions) filed by 110+ different entities. The report provides a detailed analysis of the IP landscape and noteworthy patents concerning halide solid electrolyte materials. This new IP report is complementary to our previous patent landscape reports and patent monitors on solid-state batteries.
IP competition analysis should reflect the vision of players with a strategy to enter and develop their business in the solid-state Li-ion battery market. In this report, Knowmade's analysts provide a comprehensive overview of the competitive IP landscape and latest technological developments in this field. The report covers IP dynamics and key trends in terms of patents applications, patent assignees, filing countries, and patented technologies. It also identifies the IP leaders, most active patent applicants, and new entrants in the IP landscape. The report also sheds light on under-the-radar companies and new players in this field.
In this report, we analyze the strength of patent portfolios and the technology and application focus of key patent assignees. An overview of the current status and trends of patented technologies and their applications is also provided. Furthermore, the report examines the strategic and technological directions of both leading companies and newcomers in the field.
The patents have been manually categorized according the claimed material compositions (LiMX4, Li3MX6, halide material alone, halide material with a shell, halide material mixed with another material), the claimed manufacturing methods (mechano-chemical, co-melting, liquid-phase), as well as the challenges/solutions and the best materials/ionic conductivities at room temperature disclosed by the inventions.
Panasonic/Sanyo is leading the halide solid electrolytes patent landscape, challenged by Samsung, GLABAT, SVOLT, Saint-Gobain, and TDK. Additionally, the IP analysis allowed us to pinpoint over 60 IP newcomers who filed their first halide-related patents in 2022 or after: EVE Energy, Korea Electronics Technology Institute (KETI), Liongo New Energy, Qingtao Energy Development, Global Graphene, etc. 80% of new entrants in the patent landscape come from China. In a dedicated section, we focus on the IP portfolios held by key players (Panasonic, Samsung, Saint-Gobain, GLABAT, SVOLT, EVE Energy, University of Western Ontario, TDK, Toyota, etc.). For each, we provide an overview of their patent portfolio related to halide solid electrolytes and a description of their key patented technologies.
This report also includes an extensive Excel database with all patents analyzed in this study. This useful patent database allows for multi-criteria searches and includes patent publication numbers, hyperlinks to an updated online database (original documents, legal status, etc.), priority date, title, abstract, patent assignees, and segments (challenges/solutions, material composition, halide formula, synthesis methods, etc.).
