Lithium Cobalt Dioxide (LiCoO2) is a chemical compound commonly used in the positive electrodes of lithium-ion batteries. [Molecular Formula] LiCoO2; [CAS No.] 12190-79-3.
The material was packed in one layer aluminum foil bags with a blue drum outside, 25kg per bag. There were total of 10 batches, 200 drums/batch, total 2000 drums. Packing was found in normal condition as per visual inspection. The crystal structure is denoted R\bar 3m in Hermann-Mauguin notation, signifying a rhombus-like unit cell with threefold improper rotational symmetry and a mirror plane. Location of material is stored in an indoor warehouse. The cargo is found to be black powder, no extraneous contamination was noted as far as visible and accessible.
Sampling was performed according to GB/T 5314, 12 bags for each batch was randomly selected for sampling purpose, 3 increments/, middle and left of each bag). Samples were taken from each selected bag using a standard plastic tube, more than 5kg per batch. All sampled packages were stuck with SGS labels. Final accumulated sample was thoroughly blended, the sample reduction and division be method of coning and quartering. More simply, however, both lithium and cobalt are octahedrally coordinated by oxygen. Each cobalt atom is aligned on a common axis with lithium atoms and separated from each lithium atom by a triangle of oxygen atoms as can be seen in the figures. The final sample for each batch was divided into 7 sets by grid method. The marking is pased on each drum from 1010001 to 1010010, total 10 batches.
Lithium cobalt oxide materials ( LiCoO2) for lithium ion battery with the following advantage:
Product Performance :
1.High tap density, D50 bigger size, Small BET area surface.
2.Diameter distributing equality, BET surface area well, Single crystal structure, High crystallinity.
3. Machining & Security of battery well
4.Excellent electrochemical performance, High capacity, Rate of holding capacity.
