By applying advanced spheroidizing techniques, we uses high quality natural scale graphite as raw material to manufacture spherical grapite, which is a lithium ion battery negative electrode material with different purity and fineness, and has the characteries such as high degree of sphericity and high tap density.

Type: THD-12-40

Property: Strong chemical stability, high charging/discharging capaciry, long circle life, and eco-friendlliness.

Use: Mainly used in lithium ion secondary battery.

Index can be adjusted according to client requirement.

As a nonmetal mineral substance,graphite is of the following physical and chemical properties:high temperature resistances,oxidation resistance,erosion resistance,heat resistance,shake resistance,high strength ,high flexibility,high self-lubrication,high conductivity of heat and electricity.As an indispensable nonmetal raw material in current high technolohy industry,the graphite products manufactured by Tianhe are mainly applied to the following industries:metallurgy,machinery,electronics,battery,chemical industry,light industry,military industry,national defence,astronavigation,and fire resistance industry.

Our company owns a graphite mine with the largest reserve in China so its graphite products are noted for property stability and consistence. In addition, the company exploits high-grade natural graphite ores and conducts multi-stage grinding, multiple floatation selection, chemical and electro-chemical purification and ultra-micro pulverizing. Upon request, we produce graphite products with 80~99.9% carbon content and 0.5~500 micron size and satisfy customer's special requirements in content of moisture, ash, above- and under-sieve and microelement as well as grain size distribution.
