Insights
Sunrise and Songci developed a CVD fluidized bed system that materially advances silicon‑carbon anode manufacturability and supports scale-up for solid‑state batteries.
The collaboration pairs Sunrise materials know‑how with Songci Electromechanical equipment capability to deliver a CVD fluidized bed system engineered for high deposition and coating uniformity, precise thermal and concentration control, and AI‑enabled process management. These technical features directly address long‑standing uniformity and consistency limits of conventional CVD for silicon‑carbon composites and, as reported, improve key device metrics: energy density, first‑cycle efficiency, and cycling stability.
Key dependencies and risks remain: successful transfer from prototype to continuous industrial operation, reproducibility across batches, and integration with downstream electrode and cell‑level processes. Outcomes hinge on manufacturing yield, capacity ramp timelines, and verification of the claimed performance gains at cell scale rather than only material level.
Watch for pilot production milestones and cell‑level validation over the next 6–24 months, third‑party test data confirming
DOVER, USA, Oct. 09, 2025 (GLOBE NEWSWIRE) -- Sunrise New Energy Co., Ltd. (“Sunrise,” the “Company,” “we,” or “our”) (NASDAQ: EPOW) today announced that its subsidiary, Sunrise (Guizhou) New Energy Materials Co., Ltd., has successfully co-developed an industry-leading CVD fluidized bed system for silicon-carbon anodes in collaboration with Songci Electromechanical Technology Co., Ltd., a holding subsidiary of AUTEWEI Technology Co., Ltd., a top-tier manufacturer in the photovoltaic and semiconductor equipment sectors. This achievement marks a major technological breakthrough in the industrialization of silicon-carbon anode materials and signifies a new milestone in Sunrise’s continuous innovation in advanced anode processing equipment, accelerating the commercialization of solid-state batteries.
