A potassium-ion battery or K-ion battery (abbreviated as KIB) is a type of battery and analogue to lithium-ion batteries, using potassium ions for charge transfer instead of lithium ions. It was invented by the Iranian/American chemist Ali Eftekhari (President of the American Nano Society) in 2004.
Potassium-ion batteries (KIBs), as one of the most promising alternatives to lithium-ion batteries (LIBs), are attracting increasing research interest due to the abundant resource of potassium and low cost.
There are multiple possible applications for potassium ion batteries. These mobile phones. One of the most famous types of rechargeable batteries is the lithium-ion battery, where its high-power density makes it ideal for portable, energy-hungry devices like smartphones.
However, potassium and potassium-ion batteries also face safety issues, and nonflammable electrolytes are not yet available for them. Materials scientist Zaiping Guo, and her team from the University of Wollongong, Australia have found a solution.
The battery industry demands dilute electrolytes, which are cheaper and ensure better performances. By using potassium ions, however, the concentrations could be reduced, the authors reported.
One of the challenges for using potassium ions in rechargeable batteries is that their large sizes can make it difficult to incorporate them in the tight-packed lattice frameworks that make up the type of electrons used in lithium-ion batteries.

Researchers demonstrated a potassium-air battery (K-O2) with low overpotential. Its charge/discharge potential gap of about 50 mV is the lowest reported value in metal−air batteries. This provides a round-trip energy efficiency of >95%. In comparison, lithium–air batteries (Li-O2) have a much higher overpotential of 1–1.5 V, which results in 60% round-trip efficiency.
