Abstract High ionic conductivity and Li + transference number are crucial for ensuring the high safety energy density of solid‐state batteries, particularly those using lithium metal anodes (LMAs). However, performance current polymer electrolytes in these areas remains suboptimal, primarily due to insufficient transport properties hindered by strong coordination between ions chains. In this work, entropy is modulated through four types anions (TFSI − , DFOB BF 4 FSI ) reduce strength chains, thereby lowering barrier transport. Additionally, promote formation a uniform F‐ B‐rich solid electrolyte interphase on LMA surface. As result, fabricated with (HESPE) exhibits 0.238 mS cm −1 0.707 at room temperature. The assembled Li/HESPE/LiFePO batteries demonstrate improved plating/stripping behavior present stable cycling 1000 cycles without short circuit 1.5 C. high‐entropy strategy presents promising approach design industrial application enhanced stability safety.
