Purified, thermally exfoliated natural flake graphite, Superior Graphite Co. (USA)... 

Natural flake graphite has been initially upgraded by flotation technologies to reach a carbon level in the order of 95%C. Such precursor has been heat-treated at high temperature to bring the carbon content up to... 

Performance of Thermally Purified Spheroidal Natural Flake Graphite SLA 1020 and Surface Coated Natural Graphite SLC1115... 

Two forms of carbon materials are used as additives in the battery industry carbons and graphites. Carbons, in turn, are carbon blacks, activated carbon, etc. Graphites are also available in several forms purified natural flake graphites, expanded graphites, synthetic spherical graphites, etc. Table 7.1 summarises the basic characteristics (particle size, specific BET surface area, trade name) of some of the commercially available carbon and graphite materials. 

Exfoliated graphite is usually prepared from well-crystallized natural flake graphite It is used for the production of graphite foils. Exfoliated graphite is different from the deflagration product of graphite oxide (graphitic acid). 

Natural flake graphite is not used for the production of carbon cathode blocks, mainly because of economics, but also probably because the addition of flake graphite doesn t considerably increase the properties of carbon cathode blocks (as it takes place with the addition of flake graphite for refractories for ferrous metallurgy). 

The materials used in this study include (a) natural flake graphite and sodium dodecyl sulfate (SDS) from Sigma Aldrich, (b) the aniline monomer was obtained from Aldrich and purified by vacuum distillation and kept under nitrogen in a refrigerator at about 4°C prior to use, (c) medium molecular weight chitosan powder with = 480 KDa and DD = 75-85%...
