Japanese players have a good IP position in the solid-state Li-ion battery field

Solid-state batteries with inorganic solid electrolytes hold a key position in the booming developments to get safer Li-ion batteries for electrical vehicles (EVs) with greater autonomy and maximum speed. Solid-state batteries can be classified into two categories: thin-film solid-state batteries and “bulk” solid-state batteries.

The thin-film technology approach proven for thin-film solid-state batteries is not directly applicable for bulk solid-state batteries. New processes and materials, therefore, have to be developed to get bulk solid-state batteries up to market requirements (performance, stability, cost).

There are currently three main axes for development to enhance bulk solid-state battery performance: improve solid electrolyte performances; improve the electrode/electrolyte interface, and develop material/cell assembly manufacturing processes compatible with industrial production.

Many companies have recently presented solid-state battery prototypes and announced their commercialization and integration in electric vehicles by 2025. However, many questions remain: which solid electrolyte has the most promising performance? What are the most recent technological developments? Who has the best position across the supply chain? In this context, the publisher is releasing a new patent landscape report covering the whole value chain of solid-state Li-ion batteries with inorganic solid electrolytes from electrolyte materials to electrodes and battery cells.

Patent landscape analysis is the perfect complement to market research, to fully comprehend the competitive landscape and technology roadmap, keep abreast of cutting-edge technology developments, anticipate future technology adoption, and understand the different competitors’ strategies. This kind of patent landscape report reveals the companies, technical solutions and strategies not identified through standard market analysis.

The publisher’s analysts have selected and analyzed more than 14,400 patent filings grouped into 7,300+ patent families (inventions) related to solid-state Li-ion batteries with inorganic solid electrolytes. In this report, the publisher reveals the main IP trends, key patented technologies, recent development trends, key IP players and newcomers, their strategies regarding inorganic solid electrolyte materials, and their IP strategies and strengths by supply chain segment and inorganic electrolyte material.

Understand the competitive landscape and IP strategy of key players

The publisher has identified more than 1,000 different entities that have filed patent applications related to inorganic-based solid-state Li-ion batteries. The report provides a clear overview of the most active patent assignees as well as a presentation of newcomers to the patent landscape.

Furthermore, patent segmentation reveals the IP position of patent assignees by supply chain segment (electrolyte materials, electrodes, battery cells) through a detailed analysis of their patent portfolios. The publisher also provides insights into the key 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 supply chain segment, on the basis of their IP portfolio size, prior-art contribution, geographical coverage of the IP portfolio, and enforceability of their patents. A special focus is placed on the main IP collaborations (co-filings, license agreements, transfer of IP rights) related to solid-state Li-ion batteries with inorganic solid electrolytes.

Identify the leading IP players and IP newcomers across the supply chain, by electrolyte material

All patents selected for this study have been categorized by supply chain segment (electrolyte material, electrode, battery cells), electrolyte type (inorganic/polymer, inorganic) and inorganic electrolyte material (argyrodite, Thio-LISICON, sulfide glass-ceramic, oxide glass-ceramic, perovskite, anti-perovskite, LISICON, garnet, NASICON, hydride).

For each supply chain segment, 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.

Focus on key players’ patent portfolios

The report provides a detailed analysis of a selection of key players: Toyota, Samsung, LG Chem, Panasonic/Sanyo, Idemitsu Kosan, Fujifilm, Bosch/SEEO, Murata/Sony, Hyundai/Kia, QuantumScape, QingTao Energy Development, SVOLT, and OHARA. For each player, the publisher summarizes their IP portfolio, highlight their strengths and weaknesses by segment, identify their key patents and provide information about their recent IP developments.

 

Useful Excel patent database

This report also includes an Excel database with the 7,300+ patent families (inventions) 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, patent’s current legal status, and segments (electrolyte materials, electrodes, battery cells, inorganic, inorganic/polymer, sulfide glass ceramics, Thio-LISICON, argyrodite, oxide glass ceramics, NASICON, perovskite, garnet, anti-perovskite, hydride, etc.).

For patent landscape analysis, the patent information is extracted from the FamPat worldwide patent database (Questel-ORBIT) which provides 100+ million patent documents from 95 worldwide patent offices.

The search strategy combines keyword-based searches with expert review and manual screening of the patents. Keywords are searched in the title, abstract, claims and description. Relevant IPC (International Patent Classification) and CPC (Cooperative Patent Classification) are also used for the patent search. The dataset of identified patents is manually cleaned of non-relevant patents. Citing and cited patents of selected relevant patents are also included in the search strategy. The search strategy (keywords and search equations) and the dataset of selected patents is provided in our reports.

The publisher's analysts (PhD team) combine their technical and patent expertise with powerful analytics tools and proprietary methodologies to deliver the most relevant patent analyses.
