Spherical Graphite

sg(spherical graphite)
by the advanced technologies, we are able to narrow the particle size distribution. the big particles are removed by screening process. the spherical graphite has high sr/lr and tap density (up to 1.10g/ml), which is easy to make a electrode with high density. the surface of sg is quite good and the bet is low. the first discharge capacity is above 360mah/g.the efficiency is above 88%; the cycle is above 300. the particle size and purity are adjustable according to customers’ demand.
advantage:
good sphericity,chemical stability strong,high charge-discharge capacity,long cycle life,safety performance is good.
size:
there are a median diameter of 10um, 12um, 15um, 16um, 17um, 18um, 19um,20um,23um and 25um,etc.
packing:
provide various packing options according to customer requirements, including woven bags.
note: our company high-quality natural flake graphite as raw material, can be adjusted according to customer’s request technical parameters. the request can be processed according to the customer than the physical and chemical indicators of special products, using a unique shaping and classification technology, enabling product size range narrows, paging concentrated, and the use of advanced screening and mixed-technology control products, foreign body, to ensure that product stability, uniformity, consistence, crystallization of the product after processing with the good, round high quality and stability of its products first discharge capacity of 360mah/g or more charge-discharge efficiency of 86% or more is a new generation of the ideal lithium-ion secondary battery anode material.
can also produce conductive graphite, whose target is for the 2-8 micron particle size, the carbon content of 3-99.83% of the different specifications, according to the requirements of customers for further processing,
