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.

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.

Graphite is carbon crystal and nonmetal material with the natures of silver gray, soft texture, metal luster, Mohs hardness 1~2, specific gravity 2.2~2.3 and volumetric weight 1.5~1.8 in general.

Graphite features very high melting point. It starts to melt at 3000°C in vacuum and evaporates at 3600°C. Strength of most materials decreases under high temperature but, on the contrary, the strength of graphite will increase in double when it is heated to 2000°C. However, graphite’s oxidation resistance property is poor and temperature rise may quicken the Oxidation process of graphite.

Graphite is noted for excellent thermal and electrical conductivity, which is 4 times that of stainless steel, 2 times that of carbon steel and 100 times that of most nonmetal materials. Of graphite, thermal conductivity is better than that of metals, including steel, iron and lead, but decreases when temperature rises. Unlike metals, when temperature is extremely high, graphite will be of thermal insulation. So, the property of graphite in heat insulation under high temperature is accountable.
