Calcination Mortar for Cathode Materials | High Temperature Refractory Mortar

Calcination mortar for positive electrode materials

The most crucial materials for rechargeable lithium-ion batteries are the positive and negative electrode materials. We specialize in producing high-quality, corrosion-resistant calcining vessels for these materials. With the continuous expansion of mobile and IT industries and the increasing demand for low-carbon and environmentally friendly products, lithium-ion batteries (using high-performance, low-carbon, and environmentally friendly materials) are gaining a larger share of the rechargeable battery market. Addressing the stringent requirements of calcination processes for ternary and lithium iron phosphate positive and negative electrode materials, our company specializes in producing high-quality, corrosion-resistant calcining vessels. These vessels possess strong corrosion resistance and low impurity content, ensuring the purity and consistency of the positive electrode material calcination process.
