Potassium Fluoride and Carbonate Lead to Cell Failure in Potassium-Ion Batteries
ACS Applied Materials & Interfaces, 2021While Li-ion is the prevailing commercial battery chemistry, the development of batteries that use earth-abundant alkali metals (e.g., Na and K) alleviates reliance on Li with potentially cheaper technologies. Electrolyte engineering has been a major thrust of Li-ion battery (LIB) research, and it is unclear if the same electrolyte design principles ...

Potassium Alloy Reference Electrodes for Potassium-Ion Batteries
ECS Meeting AbstractsPotassium-ion batteries (KIBs) represent a promising complementary technology to lithium-ion batteries due to the availability and low cost of potassium. KIBs could also be produced with graphite anodes and Prussian blue analogue (PBA) cathodes, reducing the demand for rare, costly elements necessary in LIBs.1 However, accurate characterization of ...
