鹵化物固態電解質：固態電池的一個有前途的選擇

近幾十年來，固態鋰離子電池由於其安全性和高能量密度潛力的顯著優勢而引起了廣泛的關注。具有快速離子傳輸和優異穩定性的固態電解質（SE）對於這種有前途的下一代鋰電池的商業化至關重要。因此，對無機固體電解質如硫化物電解質和氧化物電解質的研究已經積極進行。然而，兩者都未能實現電導率和穩定性之間的最佳平衡。氧化物的晶界阻抗高，硫化物的穩定性低。然而，鹵化物基固體電解質具有室溫離子電導率（>10-3 S.cm-1）、與氧化物正極材料良好的相容性以及優異的化學穩定性和可擴展性，因此被認為是其中之一。

對鹵化物固體電解質日益增長的興趣也透過監測固態鋰離子電池相關專利得到證實。截至2023年9月，已公開與鋰離子電池鹵化物固態電解質材料相關的專利330餘項。對於從事固態電池行業的公司來說，現在至關重要的是從技術、競爭和智慧財產權 (IP) 的角度審查這些新興材料。

Halide solid electrolytes are promising options for solid-state batteries

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.

Understanding the main trends, the key players' IP position and IP strategy

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.

What are the patented technologies?

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.

A few IP leaders and numerous IP newcomers

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.

Useful Excel patent database

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.).
