From Patent Clusters to Co-Developed Standards | How AutoRICH Intelligent’s Dry Electrode Line Tackles the Hard Nut of Solid-State Battery Mass Production?

The race toward solid-state battery industrialization is elevating dry electrode technology from an “alternative process” to a preferred route. Featuring solvent-free operation, low energy consumption and broad compatibility, the dry process is widely recognized as a key enabler for mass production of high-energy-density solid-state batteries. Nevertheless, this route demands robust engineering support. Uniform electrode film formation, consistent fibrillation, and stable yield under continuous production all represent formidable engineering gaps between laboratory R&D and commercial manufacturing.

AutoRICH Intelligent’s approach is to consolidate fundamentals with patents, define benchmarks through standards, and turn “technical feasibility” into “mass manufacturability” via integrated solutions.

01 Dry Electrode Lab Line & Production Line: Two Turnkey Solutions

Targeting the pain points of solid-state dry electrode processes, AutoRICH has rolled out two turnkey packages: a lab-scale dry electrode line and a full-scale production line. The lab line is built for formula development, process exploration and sample preparation. It enables rapid process validation and shortens R&D cycles for customers. The production line is designed for large-scale manufacturing, integrating powder conveying, mixing, forming, calendering and lamination. Engineered for stability, consistency and automation, it lays the foundation for qualification and mass ramp-up, bridging the “last mile” from lab to factory floor.

02 Confidence for Technical Breakthroughs Rooted in Solid Know-How and IP Portfolio

For core processes of solid-state dry electrodes including powder mixing, fibrillation, shaping and granulation, and electrode forming, AutoRICH has secured multiple granted invention patents. Representative patents include:

• A dry electrode preparation system and manufacturing method
• A dry mixing system and its control method
• An internal mixer and its cooling method
• AI-based dry electrode forming control method and integrated forming-lamination machine
• A continuous calendering system

These patents leverage intelligent algorithms and equipment technology to improve dry electrode consistency and enhance process controllability.

03 Beyond Technological Innovation: Deep Engagement in Industry Standardization

AutoRICH led the development of the group standard Technical Specification for Dry Electrode Equipment of Solid-State Batteries (T/TMAC 256-2025), which has been officially released. Filling a gap in industry specifications, the standard defines eight core subsystems for dry electrode equipment: dry mixing, dry kneading, fibrillation and granulation, roll-to-film calendering, roll lamination, dry compression forming, control system and auxiliary systems. It provides a unified top-level framework for equipment design, manufacturing and acceptance. In an emerging sector where process routes are still evolving, unified technical terminology for equipment facilitates industrial chain collaboration and accelerates commercialization. AutoRICH is contributing to this foundational “common language” for the industry.

Building on core patents, standard-setting work and commercialized lab & production lines, AutoRICH keeps removing industrialization barriers for solid-state dry electrodes, driving the new energy industry toward higher energy density, improved safety and greener manufacturing.

The integrated dry electrode solutions for solid-state batteries were showcased at CIBF 2026 in Shenzhen. Thanks to high compatibility and scalable capacity, they have attracted attention and cooperation intentions from leading battery makers. Multiple lab lines for sulfide-based solid-state dry electrodes have already been delivered. By eliminating solvents and VOC emissions at the source, the dry process cuts energy consumption for solvent recovery and reduces electrode manufacturing costs. Green manufacturing is no longer an optional extra — it becomes a core competitive advantage in mass production.

The final form of solid-state batteries is yet to be determined, but the foundation of complete dry electrode equipment is being laid piece by piece.

AutoRICH aims to integrate patents, standards and line capabilities into a cohesive system. This helps solid-state battery manufacturers reduce the complexity of developing and integrating dry-process equipment, avoiding redundant ground-up development.

The value of technical breakthroughs lies not only in outpacing competitors, but also in building a reusable engineering roadmap for the whole industry.
