Dublin, May 13, 2024 (GLOBE NEWSWIRE) -- The "Halide Solid Electrolytes for Li-ion Batteries Patent Landscape 2024" report has been added to ResearchAndMarkets.com's offering.
In this report, the 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.
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.
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, the 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.
