Changsha Zhongci New Material Technology Co., Ltd. is a professional manufacturer specializing in high-performance ceramic and graphite products. Our core business spans thermal field consumables for lithium batteries, supporting materials for PV energy storage, industrial electronic ceramics, and precision grinding media. We are dedicated to enabling high-temperature sintering, graphitization, powder processing, and power transmission applications across the new energy, electronics and advanced manufacturing sectors.
- Ceramic saggers: including corundum-mullite and cordierite-mullite saggers (mullite cordierite saggers), with an annual capacity of 4 million units
- Graphite saggers: annual capacity of 600,000 units
We engineer application-specific saggers for a wide range of material systems, including ternary cathode materials (NCM/NCA), sodium-ion battery materials, lithium cobalt oxide (LCO), lithium manganate (LMO), lithium iron phosphate (LFP), and cathode materials for PV energy storage systems. These products serve as critical kiln furniture consumables for the high-temperature sintering of cathode and anode materials.
Our alumina-based ceramic product line includes cement resistor shells and alumina ceramic rods, with a total annual capacity of 2,000 tons. Featuring outstanding high-temperature resistance, electrical insulation and mechanical strength, these products are widely deployed in industrial power electronics, PV inverters, energy storage converters, high-temperature kiln transmission systems, and high-voltage insulation components.
With an annual capacity of 1,000 tons, our grinding media are engineered for fine grinding and uniform dispersion of powder materials. They are extensively used in the production of lithium battery electrode materials, PV photovoltaic powders, non-metallic minerals, and high-performance ceramic powders.
Leveraging our proprietary core compression molding technology, our graphite saggers deliver exceptional flexural and compressive strength. Compared with traditional assembled or solid-machined graphite saggers, our solutions outperform in production output, cost efficiency, manufacturing yield and quality consistency, and have earned wide recognition in the market. Our proven expertise in ceramic formulation and precision molding also underpins our industrial ceramic and grinding media lines, enabling stable performance and fully customizable solutions for diverse industrial scenarios.
We maintain close strategic partnerships with leading manufacturers across the lithium battery, PV energy storage and industrial electronics sectors, covering all top-tier domestic players in our served markets.
