Abstract Red phosphorus (RP) has received much attention in potassium storage because of its inexpensive cost and high theoretical capacity, but faces the issues volume expansion poor conductivity. Fortunately, phosphorus–selenium hybridization solves these by forming an alloy anode that combines RP's capacity with Se's But weak chemical affinity between RP Se makes it often difficult to form stable homogeneous mixtures during preparation. To address this, this study introduces hexagonal boron nitride (h‐BN) as a bridging source facilitate close coupling composite phases. The optimized multi‐component exhibits initial coulombic efficiency (ICE reaching 73.0%), good cycling stability (3000 cycles at 1 A g −1 ), outstanding rate performance (a discharge specific 157.3 mAh g⁻¹ even 2 g⁻¹). Further investigation reveals introduction h‐BN reduces activation energy for interfacial charge transfer K + cross solid electrolyte interphase (SEI). It also decreases Gibbs free change (ΔG) potassiation reaction's decisive step. Therefore, third phase enhances effect alloy‐based composites, providing method designing secondary battery electrodes capacity.
