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...

Spatially Decoupled Electron and Lithium Storage at Fe/Solid Electrolyte Interphase Interfaces

ABSTRACT Extra lithium storage in transition‐metal nanoparticles remains debated because interfacial reactions are difficult to distinguish. Using Fe/C as a model anode, we combine in situ electron paramagnetic resonance (EPR) and magnetometry to resolve two concurrent storage pr...
