Refractory Cordierite Mullite Sagger For Lithium Battery Material Calcination

Changsha Zhongci New Material Technology Co., Ltd. is a professional manufacturer focused on thermal field consumables for lithium batteries, dedicated to supporting the high-temperature sintering and graphitization processes of lithium battery cathode and anode materials.

Our core product portfolio covers:

• Ceramic-based saggers (corundum-mullite, cordierite-mullite) - annual capacity 4 million pcs.
• Graphite saggers - annual capacity: 600,000.

We develop application-specific saggers tailored for diverse lithium battery material systems, including cathode ternary materials (NCM/NCA), sodium-ion battery materials, lithium cobalt oxide (LCO) and lithium manganate (LMO),Lithium iron phosphate(LFP). These products serve as critical kiln furniture consumables for the cathode material sintering process.

Leveraging its core compression molding technology, the company delivers graphite saggers with enhanced flexural and compressive strength. Outperforming traditional assembled or solid-machined graphite saggers in output, cost, efficiency and quality, our products are highly recognized in the market.

We work closely with top lithium battery cathode & anode material makers, covering all leading domestic customers. 70% of our sales are generated from industry leaders.
