As global demand for high energy density batteries continues to grow, solid-state batteries—the next generation of battery technology—are rapidly moving toward industrialization. This evolution places higher demands on key materials, particularly silicon-carbon anodes, and the precision manufacturing equipment behind them. The successful industrialization of advanced materials ultimately depends on breakthroughs in core process equipment.

 

At this critical juncture, Songci Electromechanical, a subsidiary of Autowell, has developed CVD fluidized bed reactor designed to support the large-scale production of silicon-carbon anode materials—injecting new momentum into the solid-state battery industry’s technological advancement.

Part 1: Cross-Industry Innovation — Transferring Core Capabilities from Photovoltaics and Semiconductors to Solid-State Batteries

With a solid foundation in photovoltaic and semiconductor manufacturing equipment—particularly in monocrystalline silicon growth systems—Songci has long established itself as a technology leader.
Crystal growth processes demand exceptional precision in thermal field design, temperature control, gas flow management, and vacuum environments, while also relying on advanced remote centralized control, digital twin technologies, and AI-based automation.

Although chemical vapor deposition (CVD) operates under different process conditions, its underlying technical principles align closely with those of crystal growth. This deep process commonality has enabled Songci to transfer and extend its expertise, leading to the development of its core CVD fluidized bed technology—a pivotal step in expanding into the solid-state battery ecosystem and enabling high-quality silicon-carbon anode production.

Part 2: Core Value — CVD Fluidized Bed Reactor as the "Key Engine” of Silicon-Carbon Anode Industrialization

As the next-generation battery technology, solid-state batteries require anode materials that evolve in tandem with system innovation. Among these, high-performance silicon-carbon anodes, known for their high capacity and excellent cycling stability, have become one of the most promising routes toward large-scale commercialization.

Songci’s CVD fluidized bed reactor is purpose-built for silane deposition and carbon coating processes on porous carbon-based powders, offering several key advantages:

Superior deposition and coating uniformity

Highly precise control of temperature and concentration

Integrated big data analytics and AI-driven process control

Enhanced operational safety and system stability

The resulting silicon-carbon anode materials exhibit higher capacity, improved initial coulombic efficiency, and superior cycling performance—laying a robust technological foundation for the industrial-scale production of silicon-carbon anodes.

Looking Ahead

As the solid-state battery supply chain continues to mature, Songci Electromechanical will not only pursue further performance breakthroughs in its standalone CVD fluidized bed reactor but will also expand toward complete line solutions.
By accelerating the transition of silicon-carbon anode materials from research to mass production, Songci aims to drive innovation, efficiency, and sustainability across the global new energy industry—empowering the future of solid-state battery manufacturing.
