O3-type layered oxides are considered as one of the most promising cathode materials for sodium-ion batteries (SIBs) owing to their high initial sodium content, reversible capacity, mature synthesis process, and low production cost. However, adverse phase transition highly air-sensitive issues result in unsatisfactory cycle life poor processing properties, limiting further commercialization. Herein, we prepare a high-entropy metal oxide modified by TiB2 coating layer, which displays increasing structural stability due increase entropy. The layer prevents direct contact between electrolyte electrode, suppresses unfavorable side reaction with electrolyte. Moreover, induces part boron ions (B2−) doping into oxygen CNMT, expanding ion diffusion channels. Consequently, designed Na0.9Cu0.12Ni0.33Mn0.4Ti0.15O2@TiB2 (CNMT@TB) 1 wt% exhibits significantly improvement cycling (capacity retention 91.58% after 200 cycles at 100 mA g−1 93.90% 250 500 g−1) compared pristine CNMT (63.88% 80.07% g−1). This work provides insightful guidance simultaneously enhancing electrochemical performance batteries.

Abstract Lithium‐ion batteries (LIBs) have been widely adopted in the automotive industry, with an annual global production exceeding 1000 GWh. Despite their success, escalating demand for LIBs has created concerns on supply chain issues related to key elements, such as lithium, cobalt, and nickel. Sodium‐ion (SIBs) are emerging a promising alternative due high abundance low cost of sodium other raw materials. Nevertheless, commercialization SIBs, particularly grid storage applications, faces significant hurdles. This perspective article aims identify critical challenges making SIBs viable from both chemical techno‐economic perspectives. First, brief comparison materials chemistry, working mechanisms, between mainstream LIB systems prospective SIB is provided. The intrinsic regarding stability, capacity utilization, cycle calendar life, safe operation cathode, electrolyte, anode discussed. Furthermore, scalability material production, engineering feasibility, energy‐dense electrode design fabrication illustrated. Finally, pathways listed discussed toward achieving high‐energy‐density, stable, cost‐effective SIBs.

Layered oxides are one of the most promising cathode materials for sodium-ion batteries due to their high theoretical capacity, voltage platform, and low manufacturing cost. However, poor air stability severely limits practical application O3-type layered oxide. In this study, a simple one-step sintering coating method is explored construct uniform dense heavy metal oxide (Sb2O3) layer on Na(Ni1/3Fe1/3Mn1/3)O2 (NFM333), effectively improved NFM333 by mitigating contact H2O CO2 in air. Consequently, NFM333-0.5 wt % Sb2O3 obtains specific capacity 92.1 mAh g-1 with retention 84.6% after 200 cycles at 1C exposure 60% humidity 2 days, while without has just 85.4 65.3% same handling. This study presents facile improve NFM33, which provides insights development air-stable NFM333.
