“…For comparison purposes, the estimated rate of recycling of Li-ion battery units is currently 1-3% while that for lead acid batteries, after years of effort and a captive battery market, ranges from 80-97.5%. 3 As such, alternative battery technologies must be explored. Li-air batteries are plagued with monumental challenges 4,5 and by the time they are ready for commercialization, Li supplies may already be waning.…”

“…[6][7][8][9][10] Furthermore, recycling Li-ion battery materials is very energy intensive whereas recycling alkaline battery materials is neither as difficult nor as energy intensive. 3 It is our opinion that a concentrated research effort to bring rechargeable Zn-air cells to the market is much more sensible than the efforts currently being focused on Li-air. How then would a lab begin to do quality research on Zn-air cells without previous expertise?…”

Coin cells require small amounts of material, can have good reproducibility, are easily fabricated in large quantities and have small space requirements that allow many cells to be tested simultaneously under controlled conditions. If thin electrodes are used, concerns over bulk electrode issues can be alleviated, making coin cells an ideal research tool for testing new active materials, electrode material recipes, electrolytes and separators. This work focused on the choice of materials for the components in an alkaline Nickel-Zinc coin cell. The experiments showed that nickel should be used for all positive electrode side components, including the current collector, while tin should be used for all negative electrode side components. A non-woven separator as well as a microporous separator are both required for long cycle life. Nickel-Zinc coin cells created in this work achieved Nickel active material utilizations over 100% and cycle lives of over 300 cycles with unoptimized electrode materials. The procedures and recipes developed may be of value for researchers working on rechargeable Zn-air cells.
