Hydrogen-Bond-Coupling Interfacial Microenvironment Enables Fast Charging of Sodium-Ion Batteries Over a Wide Temperature Range.

ABSTRACT: With the deepening global energy transition and expanding diversified application scenarios, developing sodium-ion batteries with both fast-charging capability and wide-temperature adaptability has become urgent. However, the core challenge lies in constructing a stable cathode-electrolyte interface (CEI). Traditional strategies overly rely on electrolyte formulation adjustments while neglecting intrinsic material surface engineering. This study innovatively proposes a hydrogen-bond -coupling mechanism between surface hydroxyl groups on the cathode and electrolyte molecules, precisely tuning the interface microenvironment to synergistically resolve conflicts between high/low-temperature interfacial failures. Specifically, hydrogen bonding induces preferential decomposition of fluoroethylen
