In Situ Electrochemical Oxidation for High-Energy-Density Aqueous Batteries: Mechanisms, Materials, and Prospects.

To advance the commercial utilization of aqueous electrochemical devices for grid-scale energy storage, it is crucial to address the current limitations related to energy density and cycle stability. Indeed, the lack of high-performance cathodes is still an obstructive issue, not to mention the limited capacities related to the monotonic cation intercalation/deintercalation mechanism. Fortunately, conversion chemistries with redox reactions bring a new dimension, where materials with multiple valence states facilitate multi-electron redox reactions, offering the potential for high-energy-density storage.

Deciphering Closed-Pore Formation and Size-Dependent Sodium Cluster Filling Behavior for Nanopore-Confined Derived Hard Carbon Anodes.

The low-voltage plateau capacity (LVPC) of hard carbon (HC) anodes for sodium-ion batteries originates from sodium cluster filling within closed pores, and closed-pore engineering of activated carbon (AC) via nanopore-confined pyrolysis is a feasible strategy to produce HC anodes with high LVPC. However, the formation mechanism of closed pores and their size-dependent effects on sodium cluster filling behavior remain poorly understood. Herein, pitch-confined pyrolysis is utilized within the nanopores of AC to transform its open pores into closed pores, with pitch dose regulating closed-pore size.
