The coordinated development of new energy vehicles and the storage industry has become inevitable to reduce carbon emissions. cathode material is key that determines density cost a power battery, while currently developed applied can not meet requirements high specific capacity, low cost, safety good stability. High-entropy type single-phase composed multiple principal elements in equimolar or near-equimolar ratios. interaction between play an important role improving comprehensive properties material, which expected solve limitations battery materials practical applications. Based on this, this review provides overview current status modification strategies batteries (lithium-ion sodium-ion battery), proposes high-entropy design strategy, analyzes structure-activity relationship effect performance. Finally, future research topics are proposed, including computational guide design, synthesis methods, electrochemistry high-throughput databases. This aims provide guidance for next-generation batteries.

From Na to K‐Based Prussian Blue: A Path Toward Cathode Materials for Extreme Environment

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 22, 2025

Abstract Prussian blue (PB) is regarded as a promising host for Na or K storage because of its sustainable precursor elements (e.g., Mn, Fe) and open framework structure. However, unstable structure, high crystal H 2 O content, risky HCN generation restrain practical applications. In this work, after systematical investigation structural evolution from Na‐based to K‐based PB relationship with electrochemical properties, it clarified that low water trace doping are essential robust structure stable cycling PB. It found Na‐doped exhibits comprehensive properties content (3.2 wt%), thermal stability (over 340 °C), superior (84.3% 6300 cycles at 5 C). Besides, the can also present under harsh conditions, such intermittent‐overcharge/overdischarge steps (4.8 V/1.2 V, 93.3% 2100 C), in wide voltage range (93.2% 1000 1.5‒4.5 V/5 rate (83.7% 4350 10 temperature (92.0% 1650 45 °C/1 The attributed robustness even conditions.

The insufficient structure and interfacial stability of O3-type layered oxide cathode materials hinder their practical application in sodium-ion batteries, particularly at high temperatures. In this study, a thin, island-like NaTi2(PO4)3 coating layer (∼15 nm) is constructed on the surface NaNi1/3Fe1/3Mn1/3O2 through an situ reaction involving nano-TiO2, Na2CO3 NH4H2PO4. During high-temperature calcination process, partial Ti-atom diffusion into lattice results expansion interslab sodium reduction oxygen vacancies. Benefitting from stable NaTi2(PO4)3-modified interface enhanced structural stability, coated with 2 wt% exhibits optimal cycle temperature. It retains 90.3% its initial capacity after 100 cycles 0.5C (1C = 130 mA g-1, 45 °C). This dual-modification strategy, obtained facile approach, has potential to facilitate materials.
