Low-Temperature Potassium Batteries Enabled by Electric and Thermal Field Regulation

Yanfang Liu et al.

Summary: In this study, a strategy to regulate electric field and thermal field simultaneously is reported, providing a fast and uniform deposition surroundings for potassium ion in potassium metal batteries (PMBs). By using a highly ordered 1D nanoarray electrode, the electric field is uniformed and temperature fluctuation is reduced. The electrode achieves a high-areal capacity of 10 mAh cm(-2) and reveals the dependence of potassium nucleation on temperature. These findings demonstrate the validity of the strategy and provide guidelines for the rational design of advanced electrodes for PMBs.
