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. Moreover, results confirmed enhancement mechanism NaNFMO addition WO3. Such strategy provides practical method improving performance.
