American Manganese technology passes phase 3 test

AMERICAN MANGANESE INC. REPORTS: PHASE 3 SUCCESSFUL COMPLETION OF PROOF OF CONCEPT FOR UPCYCLING AND RECYCLING EV LITHIUM-ION BATTERY CATHODE MATERIAL

American Manganese Inc. has provided the following update. The phase 3 testing conducted by Kemetco Research Inc. has confirmed that rechargeable lithium-ion battery coin cells can be successfully produced from lithium-cobalt cathode material regenerated using American Manganese's proprietary process.

The resulting lithium-ion button cell battery produced from American Manganese's proprietary process was charged to a maximum of 4.2 volts and then discharged to a minimum of two volts. This charge-and-discharge test was repeated 10 times without the battery losing its chargeability.

Norm Chow, president of Kemetco, said, "Based on these preliminary results, it can be concluded that the American Manganese upcycling technology can transform spent lithium-ion battery cathode material into high-purity intermediate products (such as lithium carbonate and cobalt carbonate), as well as into lithium-ion cathode material suitable for the fabrication of new batteries."

"These results validate the AMI process," said Larry Reaugh, president and chief executive officer of American Manganese. "With this final phase testwork, we've taken lithium-ion battery cathode material from the recovered component metals through reconstitution of the cathode materials to produce working chargeable cells."

Battery fabrication and assembly

During phase 3 testing, the lithium cobalt dioxide (Li2CoO2), which was generated from experiment SCL6S and identified with 100-per-cent purity by X-ray diffraction (XRD) (please see the Oct. 14, 2016, press release for further details), was used in the lithium-ion cathode material formulation for button cell fabrication.

The cathode material was then prepared by combining a solid mixture of 90 per cent (by weight) Li2CoO2, 6 per cent carbon black and 4 per cent PVDF (polyvinylidene fluoride) with NMP (N-methyl-2-pyrrolidone). This cathode material mixture was subsequently coated onto aluminum foil and dried for two hours at 120 degrees in a vacuum oven to form the lithium-ion battery cathode.

The button cell batteries were assembled as follows: top cell case, cathode, separator, anode, spacer, ring-shaped spring and bottom cell case. The anode was made from purchased graphite. The ring-shaped spring was placed between the negative casing and the spacer to ensure adequate pressure was applied to the cell components. Both the spring and the spacer are made from stainless steel. A thin layer of polyolefin was used as the separator. The company will report on the next research and development program in a future release.
