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 (PIBs) have captured rapidly growing attention due to chemical and economic benefits. Chemically, the potential of K + /K was proven to be low (−2.88 V vs. standard hydrogen electrode) in carbonate ester electrolytes , which implies a high energy density using K-ion as the charge carrier and a low risk of K plating.
After the invention of potassium-ion battery with the prototype device, researchers have increasingly been focusing on enhancing the specific capacity and cycling performance with the application of new materials to electrodes (anode and cathode) and electrolyte.
The excellent electrochemical performance of conversion materials has accelerated their applications in potassium ion full batteries and potassium ion capacitors or potassium dual ion batteries . Actually, the electrochemical performance of conversion materials could be further improved in the future.
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.
Potassium-based dual-ion batteries (DIBs) operate on the basis of the intercalation/deintercalation of both cations (K +) and anions (PF 6− or FSI −) into/out of electrodes (Fig. 5H), aiming to fabricate low-cost, high–energy density, environmentally friendly batteries (82 – 84).
