<2025> Dry-process Electrode Patents Analysis & Technology Trends

SNE Research’s newly released report, "<2025> Dry-process Electrode Patents Analysis & Technology Trends", offers a differentiated perspective on the dry electrode process, which is rapidly emerging as an “innovative technology” within the secondary battery industry.

Rather than simply presenting dry electrode as a promising technology, this report provides a multi-dimensional analysis that includes practical considerations for implementation, collaboration strategies, and potential applications.

 

• While dry electrode offers compelling benefits such as VOC reduction, shorter processing time, and higher energy density, the fact that leading companies like Tesla have secured key patents makes it difficult for latecomers to introduce the technology without differentiation.

 

• Therefore, when introducing the process or pursuing R&D on new materials, it is essential to technically assess existing patents and establish strategic direction at the design stage.

This report aims to reduce uncertainty in business execution by systematically organizing the core elements of related patents and key considerations for industrial application.

Key strengths of this report

1. In-depth guide on patent strategy for dry electrode technology

• The report provides a multi-faceted analysis of major international patents covering core technologies in dry electrode processes such as solvent-free manufacturing and PTFE binder fibrillation, offering actionable design directions and collaboration options for latecomers.

 

• OEMs, battery manufacturers, and materials suppliers can use this report to assess practical technical questions such as whether modifying specific process parameters can lead to meaningful differentiation, and what to consider when applying the technology under different binder types, temperatures, or pressures.

2. Analysis of over 240 key patent cases and presentation of strategic portfolios

• The report analyzes more than 240 dry electrode-related patents applicable across a wide range of technologies, from supercapacitors to solid-state batteries. Rather than simply listing the patents, it identifies the specific process components addressed by each patent (e.g., binder fibrillation, post-treatment, roll pressing) and clarifies their technical context.

 

• In particular, for high-potential application areas such as high-nickel cathodes, silicon anodes, and solid-state batteries, the report provides a strategic portfolio focused on technical approaches and potential collaboration or utilization paths. This enables not only materials and equipment suppliers but also securities firms and investors to understand the value and commercial applicability of each technology from multiple perspectives.

3. Integrated analysis from market, technical, and legal perspectives

• The report goes beyond technical characteristics and advantages of dry electrode processes (such as cost savings and line efficiency improvements) to address global regulatory trends (e.g., VOC reduction), pilot line cases at OEM and battery manufacturers, and benefits in safety and energy density.

• It also explores key legal and strategic considerations such as patent publication timing and claim evolution, follow-up applications (e.g., CIP, divisional), and counter-strategy development by latecomers. These insights help stakeholders better manage risks and establish forward-looking technology roadmaps.

 

• As a result, OEMs, battery and material companies, investors, and research institutions can tailor their R&D, investment, and business strategies to enhance long-term competitiveness.

Who should read this report?

 

1. Automakers, OEMs, and battery manufacturers

 

• This report is valuable for companies considering the adoption of dry electrode processes, which offer practical benefits such as reduced CAPEX and OPEX, simplified production lines, and higher energy density. It also provides strategic insights for designing processes while taking into account potential overlap with existing patents.

 

 

2. Materials and equipment suppliers

 

• For companies supplying binders such as PTFE, PVDF, and FEP, conductive additives like carbon nanotubes and graphene, or equipment such as mixers and roll presses, this report helps identify how technical requirements are linked to patent claims in dry processing. It can also guide efforts to establish meaningful technological differentiation.

 

 

3. Investment firms and securities companies

 

• The report supports investment decisions, stock analysis, and partnership or M&A strategies by offering a grounded view of the market potential, patent barriers, and long-term value of dry electrode technologies compared to conventional wet processes.

 

 

4. Research institutes and R&D organizations

 

• By understanding pilot project cases in industry and analyzing patent portfolios, researchers can explore follow-up directions for next-generation battery R&D, including solid-state batteries, silicon anodes, and high-nickel cathodes.
