American Manganese Announces X-Ray Diffraction Results from Higher Purity Upcycled Cathode Materials

VANCOUVER, BC / ACCESSWIRE / October 14, 2016 / Larry W. Reaugh, President and Chief Executive Officer of American Manganese Inc ( TSXV:AMY; PINKS:AMYZF;FRANK:2AM), is pleased to announce that the Company has received results on The X-Ray Diffractograms on lithium cobalt oxide (LiCoO2) and cobalt tetraoxide (Co3O4) samples produced under different experimental conditions, using American Manganese’s lithium ion battery cathode powder up-cycling process. Up-cycled LiCoO2 compounds were produced by completely leaching LiCoO2 cathode powders, precipitating cobalt and lithium compounds and heat treating the precipitated compounds to regenerate LiCoO2. Similarly the up-cycled Co3O4 was produced by completely leaching LiCoO2 cathode powders, selectively precipitating Co(OH)2 from the leach solution and heat treating the precipitated Co(OH)2 to regenerate Co3O4.

Quantitative X-Ray diffraction (XRD) was used to characterize the LiCoO2 and Co3O4 compounds produced after treatment with the American Manganese process and comparing these compounds with commercial battery grade compounds purchased from a commercial supplier.

X-Ray Diffraction Results from Up-cycled Cathode Materials

Mr. Norm Chow, President of Kemetco says “The X-Ray diffractograms show that the experimental work was successful in proving that 100% LiCoO2 could be produced with the American Manganese lithium ion battery cathode material recycling / up-cycling technology (4 out of 5 experiments showing 100% conversion to LiCoO2, with the 5th experiment showing 95.98% conversion). In addition, the Co3O4 produced from the up-cycling of LiCoO2 using the American Manganese process has higher purity (100% Co3O4) than the commercial battery grade Co3O4 purchased from Sigma Aldrich (97% Co3O4).”

Larry Reaugh says “We are currently completing the production of test batteries (button cells), which will confirm proof of concept of the technology and are in the final stages of completing the US Provisional patent application on the technology.”

Table 1 summarizes the quantitative XRD analysis on the LiCoO2 samples. Table 2 summarizes the quantitative XRD analysis on the Co3O4 samples. The X-Ray diffractograms of each sample are provided in Figures 1 to 8. For graphs and tables please click here.
