Development of Improved Electrolytes for Zinc-Ion Batteries

Zinc-ion batteries (ZIBs) are promising candidates for storing significant amounts of electricity, since zinc (Zn) is widely available and inexpensive. ZIBs typically use a high-capacity Zn metal anode, metal oxide positive electrode, and aqueous electrolyte, with energy/power densities similar to lithium-ion batteries (LIBs). ZIBs offer advantages over LIBs, including improved safety, eco-friendliness and simpler manufacturing conditions. There are, however, drawbacks that restrict practical application of rechargeable ZIBs. These include relatively poor efficiency, the formation of byproducts, and poor cycling behaviour due to reactions associated with the metal oxide electrodes during battery cycling. One approach to improving ZIB performance is to modify the electrolyte through the use of additives or to design and implement new types of electrolytes. This work, which is a joint effort between Salient Energy, Inc. and researchers at the University of Alberta, is focused on developing alternative electrolytes for ZIBs, with the goal of producing better batteries.
