💡 Novelty & Significance:
This work introduces zinc borohydride as a multifunctional additive in a ternary acetonitrile-triethyl phosphate-tetrahydrofuran electrolyte, using synergistic anion-solvent engineering. The BH4− anions regulate Zn2+ solvation and promote uniform deposition, suppressing dendrites. This enables 400 h symmetric-cell cycling and 82.2% capacity retention after 2000 cycles, offering a viable strategy for high-safety, high-performance non-aqueous zinc-ion batteries.
