This study proposes an efficient, cost-effective, and industrially scalable electrode modulation strategy, which involves directly adding a small amount of high thermal conductance TiN well interface compatible WO3 to NaNi1/3Fe1/3Mn1/3O2 (NaNFMO-TW) cathode slurry, effectively reduce polarization side reactions, the Ohmic heat battery, ultimately significantly improve sodium-ion storage safety performance battery. At room temperature (RT) 1C rate, modified NaNFMO-TW exhibits reversible capacity ∼95 mAh g-1 after 300 cycles, with retention rate 82.6%, being higher than 50.7% for NaNFMO. Furthermore, assembled pouch battery retains 58.2% cycles at RT&0.5C, conspicuously superior 46.1% achieved by NaNFMO||HC In particular, adiabatic tests infrared imaging reveal marked improvement in reduction surface ∼1.3 ∼2.2 °C during 3C charging discharging, respectively.

The layered iron manganese oxide cathodes accompanied by anionic redox reaction (ARR) activity show large promise of high-energy and economical sodium-ion batteries. However, the adverse surface oxygen lattice evolution caused irreversible ARR tends to lead poor cyclic stability severe voltage decay, which limits its commercial application.

Abstract Rechargeable sodium‐ion batteries (SIBs) utilizing NaPF 6 ‐carbonate electrolytes consistently exhibit unsatisfactory cycle life at elevated temperatures, posing a significant challenge for their large‐scale commercialization.
