Phosphoric Acid Cross-linking Regulates Closed Pores for Scalable Hard Carbon Anodes

Abstract The low-voltage capacity of hard carbon anodes, governed by closed-pore structures, directly determines the energy density of Na-ion batteries (NIBs), yet rational regulation of closed pores remains challenging. Herein, we report a phosphoric acid-induced cross-linking s...

Triple‐Phase Synergistic Bulk‐Surface Engineering Enables High‐Rate and Long‐Cycling P2/O3‐Based Cathode for Na‐Ion Batteries

ABSTRACT Layered oxide cathodes hold great promise for Na‐ion batteries (NIBs) but suffer from rapid performance degradation under high voltage, primarily arising from severe lattice strain, transition metal migration, and detrimental surface degradation. Here, we report a triple...
