Graphite powder for batteryVarieties: a. Spherical graphite b. Graphite for alkali battery c. Dilatable graphite powder
a. Spherical graphite
Spherical graphite adopts excellent natural scale graphite as material and utilizes advanced process techniques to change the property of the surface and produce products of various finenesses in the shape of ellipsoid. It is a new generation of cathode material for the production of lithium ion secondary battery both at home and abroad.
Property: It has excellent electrical conductivity, good chemical stability, large capacity for electricity charge and discharge, long service life and environmental friendliness.

b. Graphite powder for alkali battery
Property:It owns high purity, low content of harmful elements (like Fe、Cu、Mo、Pb etc.) and low gassing quantity. The progressive technique in the process of production is able to inspect and strictly control manifold microelements in graphite. The technological index of our products stands a leading position in the same industry of our country.

c.Dilatable graphite powder:
   First the dilatable graphite will inflate into wormlike substance in high temperature then it is crushed into the size of 75~45μm by special crusher. It can be used as material of alkali battery anode with low mercury or non-mercury. The application of the material in this aspect can reduce the use volume of the similar products by 31% while increasing the use volume of manganese powder, resulting in prolonging the life of battery.
