27A Crystallization-Resistant, Temperature-Immune MFC is Gaining Traction in Silicon-Carbon Anode Manufacturing
Laminar Flow Differential Pressure MFCs Precisely Overcome Challenges of Temperature Swings and Crystallization.
How can we achieve longer battery life for your phones and electric vehicles? The answer lies in "Silicon-Carbon Composite Anode Materials!" As the next-generation anode material for lithium-ion batteries, silicon-carbon composites have attracted significant industry attention due to their remarkably high theoretical specific capacity of 4200mAh/g.
However, their production via fluidized bed Chemical Vapor Deposition (CVD) processes has long been plagued by three major pain points for manufacturers:
Demanding Environmental Adaptability: Fluidized bed CVD equipment is often located outdoors. Annual temperature fluctuations exceeding 50°C cause severe measurement drift in thermal Mass Flow Controllers (MFCs).
Critical Contamination Resistance: During silane deposition, silicon dioxide crystals form and can adhere to the inner walls of thermal MFC capillaries. This alters the heat transfer characteristics, leading to inaccurate readings.
High Maintenance Burden: Frequent crystal contamination not only disrupts process stability but also significantly increases equipment maintenance frequency and costs.
Laminar Flow Differential Pressure MFCs Offer a Groundbreaking Solution
Core Technical Advantages:
The differential pressure sensing principle is based on the Hagen-Poiseuille law, calculating flow rate by measuring the pressure drop across a laminar flow element.
The innovative overall design eliminates capillary tubes. All process gas flows through the main channel, which features a straight, unobstructed flow path without sharp bends. This structural design inherently reduces sites for silicon dioxide adhesion. Even minor crystal formation does not disrupt the established laminar flow profile, allowing the MFC to maintain accurate flow measurement.
