The purity of lithium battery cathode and anode materials directly determines the safety and endurance performance of battery cells. Metal debris produced by the wear and shedding of metal parts in the production line and mixed into raw materials is one of the main causes of unqualified material batches. Traditional carbon steel and stainless steel structural parts are extremely prone to generating metal debris under high-speed grinding working conditions. With high chemical inertness and excellent anti-wear and anti-shedding properties, alumina ceramic has become the preferred core component for powder purification processes.

Dongguan Zhongli Nano’s nano alumina ceramic components are pressed and sintered with high-purity ultrafine powder raw materials. The material features stable performance, does not react with acidic or alkaline lithium battery raw materials, and produces no precipitated impurities to contaminate materials during the whole process. Modular ceramic bushings and wear-resistant kits are designed for powder-contact positions such as feed inlets, grinding cavities and shunt pipelines, which can directly replace original

Strict purity control is implemented for raw materials during production to avoid impurity powder from mixing into the blanks. After sintering, precision grinding and polishing are performed, creating ultra-smooth inner walls that prevent material adhesion and residue, effectively reducing material waste and cross-contamination. The full set of customized solutions supports one-to-one surveying and mold development according to equipment models, flexibly adapting to both small-batch trial production and mass

As lithium battery industry quality inspection standards become increasingly stringent, more and more equipment manufacturers are comprehensively replacing metal wear-resistant accessories with non-metallic parts. Taking advantage of its location in Dongguan, Zhongli Nano quickly provides on-site service to confirm working conditions and deliver customized ceramic component solutions. Adopting a factory-direct supply model to eliminate intermediate costs, the company helps upstream new energy industry chains achieve clean production.
