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. and 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.
The company production bases covering a total area of 68,000
square meters. over 300 employs. Its revenue has exceeded RMB 250
million over the past three years
