Characteristics:
Product is made from high quality mineral resources. it is produced by multiply-grinding, fractionating, shaping, nodulizing, purifying, drying and screening crystalline flake graphite. the spherical degree of the particle is high; the tap density is big; the specific surface area is small; the uniformity of products of the same batch is high and the granularity is intensively distributed. after being made into electrode, the initial discharge capacity is as much as 369 mah/g, with an initial efficiency of over 95%, which has strictly control selecting and advanced spheroidizing process and suitable for lithium ion battery anode materials' solid phase, liquid and other coated method.
