Implication

Randomized trial demonstrates improved ion transport in potassium-ion batteries, suggesting better performance.

Key Points

The study aims to address the limitations of conventional electrolytes in potassium-ion batteries (PIBs) through a novel dipole-engineered electrolyte.
Designed a dipole-engineered electrolyte enabling transient polarized cavities during K+ desolvation.
Evaluated ion transport and solid electrolyte interphase formation in graphite anodes.
Conducted long-term cycling tests over 1000 cycles.
Achieved a high capacity of 290 mAh g−1 at 50 mA g−1 with negligible decay after 16 months (> 1000 cycles).
Maintained 226 mAh g−1 capacity even at higher rate of 500 mA g−1.
Demonstrated enhanced K+ kinetics due to localized negative electrostatic potentials.
