Abstract: Potassium ion batteries can meet the requirements of energy storage system owing to their advantages of low cost, long life and high energy density, since potassium is the element with abundant resource, low price and low electrochemical potential. However, challenges coming from disadvantages of larger and heavier of potassium ion still confront of the development of electrode materials and electrolyte for potassium ion batteries. In recent years, the high capacity electrode materials and electrolyte of potassium ion batteries have been studied extensively under the traction of electric vehicles and energy storage applications. The cathode materials such as Prussian blue and its analogues, transition metal oxides and polyanionic materials show the application prospect. Available anode materials consist of carbon, titanium and alloy materials. Effective electrolytes involve ester-based electrolytes and ether-based electrolytes. These results are significant for the basic and applied research of potassium ion batteries.
