This study addresses these challenges through molecular-level regulation of ion-dipolar and dipolar-dipolar interactions by introducing methanol (MeOH) as a cosolvent into a water-in-salt electrolyte (21 mol kg-1 LiTFSI/H2O), forming a diluted hybrid electrolyte. Results reveal that MeOH disrupts the original Li+-TFSI− binding via competitive ion dipolar coordination while reconstructing the hydrogen-bond network through preferential MeOH–H2O interactions. This dual regulation reduces the desolvation energy barrier for Li+ migration, suppresses parasitic interfacial reactions, and creates a low-freezing-point eutectic microenvironment. The optimized electrolyte exhibits an ultrawide liquid-phase range (−60 to 25 °C) and achieves an ionic conductivity of 2.8 mS cm−1 at −40 °C. The carbon-based supercapacitors demonstrate unprecedented cyclic durability with 94.2 % capacitance retention after nearly100,000 cycles at 2 V and maintain 84.3 % of room-temperature capacitance at −40 °C, showing superior cryo performance.

Here, we concurrently address these challenges by the strategies of co-doping of tantalum (Ta) and strontium (Sr) in LiNi₀.₉₂Co₀.₀₅Mn₀.₀₃O₂ (NCM92) to modulate the microstructure of NCM92 (1.0 ST-NCM92) and surface modification of perovskite-type SrLi₀.₂₅Ta₀.₇₅O₃.
