Better aqueous potassium-ion batteries
C&EN Global Enterprise, 2019Rechargeable batteries that feature an aqueous, potassium-based electrolyte have been sitting on battery designers’ drawing boards for years. Compared with popular lithium-ion batteries, which depend on an electrolyte solution of expensive lithium salts in flammable organic solvents, aqueous potassium-ion batteries (AKIBs) could offer advantages in ...

K2Ti6O13 nanorods for potassium-ion battery anodes
Journal of Electroanalytical Chemistry, 2019Abstract In this work, K2Ti6O13 nanorods have been synthesized and evaluated as potassium-ion battery anode material. A reversible capacity of 95.7 mAh g−1 at 0.01 A g−1 is obtained by this K2Ti6O13 nanorods electrode, and its robust structure survives after long cycling.

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 ...
