Abstract：Potassium/potassium-ion based electrochemical energy storage systems have many advantanges, such as high abundance of potassium, low equilibrium potential of K+/K, high ionic conductivity of K+, and so on. Potassium-ion battery/supercapacitor, K//O2 battery and K//S battery are catching massive attentions and facing challenge of lacking high-voltage potassium-ion storage materials for practical application. Thus, it is of great significance to construction of novel potassium/ potassium-ion based electrochemical energy storage systems. In this work, a potassium-organic radical battery of K//PTVE was successfully constructed, and its electrochemical performance was investigated. K//PTVE showed high discharge voltage of 3.63 V, good rate capability and cycle stability.
