AMERICAN MANGANESE INC. ANNOUNCES X-RAY DIFFRACTION RESULTS FROM HIGHER PURITY UPCYCLED CATHODE MATERIALS

American Manganese Inc. 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 upcycling process. Upcycled 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 upcycled Co3O4 was produced by completely leaching LiCoO2 cathode powders, selectively precipitating Co(OH)2 (cobalt(II) hydroxide) 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 upcycled cathode materials

Norm Chow, president of Kemetco, said: "The X-ray diffractograms show that the experimental work was successful in proving that 100 per cent LiCoO2 could be produced with the American Manganese lithium-ion battery cathode material recycling/upcycling technology (four out of five experiments showing 100-per-cent conversion to LiCoO2, with the fifth experiment showing 95.98-per-cent conversion). In addition, the Co3O4 produced from the upcycling of LiCoO2 using the American Manganese process has higher purity (100 per cent Co3O4) than the commercial battery-grade Co3O4 purchased from Sigma Aldrich (97 per cent Co3O4)."

Larry Reaugh said, "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 U.S. provisional patent application on the technology."

A table on the company's website summarizes the quantitative XRD analysis on the LiCoO2 samples. Another table on the website summarizes the quantitative XRD analysis on the Co3O4 samples. The X-ray diffractograms of each sample are provided in images on the company's website.
