Dublin, Jan. 20, 2020 (GLOBE NEWSWIRE) -- The "Solid Electrolytes for Li-ion Solid-State Batteries Patent Landscape" report has been added to ResearchAndMarkets.com's offering.

This report focuses on solid electrolyte materials. More than 5,800 patents grouped in 2,760 patent families are related to solid electrolytes for solid Li-ion batteries.

In this report, we reveal the main IP trends, key patented technologies, recent development trends, key IP players and newcomers and their IP strategies/strengths by solid electrolyte material (polymer, polymer/inorganic, inorganic, argyrodite, Thio-LISICON, sulfide glass-ceramic, oxide glass-ceramic, perovskite, anti-perovskite, LiSICON, garnet, NASICON, hydrides, etc.).

Everyone still recalls the drama surrounding the Samsung Galaxy Note 7 smartphone, which revealed a major drawback for today's Li-ion batteries: the safety risk induced by the use of liquid-flammable electrolytes.

One technical solution envisioned for improved safety is to replace the liquid electrolyte with a solid electrolyte. Solid-state batteries can be categorized into two categories: thin-film solid batteries and bulk solid batteries. The thin-film technology approach, proven for thin-film batteries, is not directly applicable for bulk solid-state batteries. Thus, new processes and materials must arise to ensure bulk solid batteries meet market requirements (performance, stability, cost).

Three main development axes are envisioned for enhancing bulk solid-state battery performance: improve solid electrolyte performances and electrode/electrolyte interface, and develop materials/cell assembly manufacturing processes compatible with industrial production. Many companies have recently announced the commercialization and integration of batteries with solid electrolytes (solid-state batteries) by 2020-2025.

However, many questions remain: which solid electrolyte exhibits the most promising performance? What are the most recent technology developments for solid electrolyte materials? Who has the best IP position in solid electrolyte materials? In this context, patent analysis is a complementary approach to market research in order to fully comprehend the competitive landscape and technology roadmap; stay abreast of cutting-edge technology developments; anticipate future technological consolidation, and understand competitors' strategies. This patent analysis also reveals the companies, technical solutions, and strategies not identified by a market analysis.

Get an overview of solid electrolyte material properties

This report provides an overview of the electrochemical and chemicophysical properties, as well as the advantages and drawbacks of the main solid electrolyte materials developed for solid-state Li-ion batteries - with a special focus on their ionic conductivities.

Understand patented technology and the competitive landscape

The 2,760+ patented inventions selected for this study are categorized by type of electrolyte (polymers, inorganic/polymer, inorganic) and inorganic electrolyte materials (argyrodite, ThioLISICON, sulfide glass-ceramic, oxide glass-ceramic, perovskite, anti-perovskite, LiSICON, garnet, NASICON, hydride). For each electrolyte material, this report includes a time evolution of patent applications, main and key patent assignees, newcomers, and a description of key and recently patented technologies. An understanding of the current technical challenges addressed in the patents is also presented. Key IP players in solid electrolyte materials are not only material manufacturers and R&D labs, but also electronic component manufacturers, battery manufacturers, and end-users.

Know key players' IP positions and IP strategies

More than 1,140 patent applicants are involved in the solid electrolyte for Li-ion solid-state battery patent landscape. This report reveals the IP position of key players, by solid electrolyte materials (polymers, argyrodite, Thio-LISICON, sulfide glass-ceramic, oxide glass-ceramic, perovskite, anti-perovskite, LiSICON, garnet, NASICON, hydride) through a detailed analysis of their patent portfolios. We also provide insights regarding these players' patented technologies, their IP strategy, and their ability to limit other firms' patenting activity and/or freedom-to-operate. The benchmarking of patent assignees is evaluated by solid electrolyte materials, on the basis of their IP portfolio size, prior-art contribution, geographical coverage, and enforceability of patents. A special focus is placed on the main IP collaborations (co-assignment, licensing, IP transfer) related to solid electrolytes for Li-ion solid-state batteries.
