High Energy Density Battery Racing! Hefei Hengli CVD Silicon Carbon & Porous Carbon Kiln Equipment, Hardcore Empowering the Industrialization Acceleration of High-End Lithium Battery Materials —— Hengli Eletek Co., Ltd. Industry Solutions for Silicon Carbon Anode/Porous Carbon Equipment

1. The Wind of the Times: The Explosion of High-Energy Density Batteries, with Equipment Determining the Industry's Ceiling

Currently, the new energy vehicle and energy storage markets have entered the era of high energy density:

- Silicon-carbon anodes are set to become the core of next-generation batteries (with a capacity over 3 times that of graphite), but four major pain points, namely CVD deposition uniformity, oxygen contamination, batch stability, and production capacity scale, are bottlenecks.

- The accelerated industrialization of solid-state batteries places stringent requirements on ultra-clean atmospheres, precise temperature control, and continuous thermal processing equipment. 

- Hengli Solutions: Drive the upgrading of the high-end lithium battery materials industry, cost reduction, and enhancement of global competitiveness with continuous, intelligent, and low-carbon equipment.

2. Core Products: CVD Silicon-Carbon Anode + Porous Carbon Equipment, with Comprehensive Technological Leadership

1. Silicon Carbon CVD Rotary Furnace (Integrated Continuous Silicon Deposition + Carbon Coating)

In the production process of CVD silicon-carbon anodes, Hefei Hengli's proprietary kiln equipment is equipped with exclusive dynamic sealing and composite flow field temperature control core technologies, enabling fully enclosed and continuous operation throughout the entire process of silicon deposition and carbon coating. The oxygen content in the equipment is stably controlled at ≤10 ppm, the utilization rate of silane is increased to over 85%, and the comprehensive production energy consumption is reduced by 22%. It has successfully overcome industry challenges such as uneven deposition, insufficient cycle stability, and large batch-to-batch variations in high-silicon-content silicon-carbon anodes, meeting the mass production requirements of 10%-30% high-silicon silicon-carbon anodes, helping enterprises significantly improve the initial Coulombic efficiency of their products, and maintaining the mass production yield rate at a high level of 95%. 

2. Specialized Roller Hearth Furnace for Porous Carbon (One-Stop Carbonization/Activation/Passivation)

In the scenario of alkali activation preparation of porous carbon materials, the dedicated roller kiln for constant-force porous carbon has been specifically optimized with anti-corrosion structure, precise temperature field, and atmosphere control system, featuring accurate and stable control, uniform and controllable pore size distribution of materials, capable of achieving kiloton-level large-scale production capacity per line, taking into account both high-quality materials and high efficiency in mass production, comprehensively meeting the production requirements of all stages from R&D and pilot testing to commercial mass production of CVD silicon-carbon anode porous carbon, and providing systematic solutions. 

3. Rotary Furnace Specialized for Porous Carbon (Carbonization/Activation)

In the scenario of preparing porous carbon materials by steam physical activation, the dedicated rotary furnace for constant-force porous carbon has been optimized in terms of its targeted furnace tube structure and rotary sealing form. By utilizing the internal structure of the furnace tube, steam preheating is achieved, and by controlling the steam flow direction, full utilization of steam is realized, significantly enhancing the activation efficiency of porous carbon, increasing the production capacity of the final product, and reducing production energy consumption. Meanwhile, through the specially designed multi-section support technology for the furnace tube, the service life of the furnace tube at high temperatures is increased by over 50%. 

3. Market Application: Validation by Leading Customers, Scale Data Demonstrates Strength

As one of the earliest domestic players to enter the market and having deeply engaged in the industry for many years, Hefei Hengli Equipment has firmly established itself as a leader in the CVD silicon-carbon anode and porous carbon thermal equipment industries, thanks to its reliable product strength and high-quality supporting services. 

Currently, the company's relevant complete sets of equipment have been put into operation in over 60% of the leading domestic silicon-carbon anode enterprises and dozens of key R&D and mass production units for solid-state batteries, with a cumulative delivery and commissioning of over 100 sets of equipment. Verified by the actual production of numerous benchmark customers, after being equipped with Hengli's equipment, enterprises have seen a significant reduction in material production costs, a steady increase in production capacity, a substantial optimization of core product performance, a short return on investment cycle, and an immediate and remarkable acceleration of industrialization implementation.
