Layered cathodes derived from precursor materials have garnered significant attention in sodium ion battery (SIB) research. However, the structure evolution mechanisms during sintering process remain inadequately understood. In this work, two precursors with irregular and regular morphologies were subjected to identical calcination conditions synthesize O3-NaNi0.4Fe0.2Mn0.4O2 cathodes. Comprehensive analysis revealed that underwent heterogeneous Na+ diffusion, resulting an R3̅m shell encapsulating a substantial rock-salt phase core solid-state sodiation process. This leads drastic transition generated unfavorable pores subsequent high-temperature contrast, quasi-spherical maintains uniform accessibility throughout process, which facilitated optimal yielded superior electrochemical performance. investigation elucidates critical relationship between morphology dynamics, providing crucial insights into rational design of precursor-derived layered SIB applications.

Sodium-ion batteries (SIBs) share similar working principles with lithium-ion while demonstrating cost advantages. However, the current understanding of their safety characteristics remains insufficient, and thermal runaway mechanisms different SIB systems have not been fully elucidated. This study investigated following two mainstream sodium-ion battery systems: polyanion-type compound (PAC) layered transition metal oxide (TMO) cathodes. Differential scanning calorimetry (DSC) was employed to evaluate stability cathodes anodes, examining effects state charge (SOC), cycling, overcharging on electrode stability. The electrolytes compositions also characterized analyzed. Additionally, adiabatic tests were conducted using an accelerating rate calorimeter (ARC) explore temperature–voltage evolution patterns temperature rise rates. systematically heat-generating reactions during various stages a comparative analysis between these systems.
