Custom High Temperature Mullite Sagger , EV Power Battery Material Sagger

Changsha Zhongci New Material Technology Co., Ltd. is a professional manufacturer focused on thermal field consumables for lithiumbattery production. We dedicate ourselves to supporting the high-temperature sintering and graphitization processes of lithium batterycathode and anode materials, delivering high-reliability kiln furniture solutions for the global new energy battery industry.

• Corundum-mullite and cordierite-mullite saggers (mullite cordierite saggers), with an annual production capacity of 4 million units
• Graphite saggers, with an annual production capacity of 600,000 units

We develop application-specific saggers tailored for a wide range of battery material systems, including ternary cathode materials (NCM/NCA), sodium-ion battery materials, lithium cobalt oxide (LCO), lithium manganate (LMO) and lithium iron phosphate (LFP). These products serve as critical consumable kiln furniture throughout the cathode material sintering and anode material graphitization processes.

Leveraging our proprietary core compression molding technology, our graphite saggers feature outstanding flexural and compressive strength. Compared with traditional assembled or solid-machined graphite saggers, our solutions deliver superior performance in production output, cost efficiency, manufacturing yield and quality consistency, earning wide recognition across the lithium battery industry.

We maintain close strategic partnerships with leading enterprises across the lithium battery industrial chain, covering top-tier cathode material manufacturers and power battery giants. 70% of our sales revenue comes from industry leaders.

Our core partners include CTAL, BYD, BASF Shanshan, Wanhua Chemical and Huayou Cobalt. In 2023, we were honored with the "Best Quality Supplier" award by Huayou Cobalt, a testament to our stable product quality and reliable supply capability.
