In the pristine state, the key cathode material LiNi0.8Mn0.1Co0.1O2 (NMC811) exhibits anisotropic mechanical behaviour due to its trigonal <math></math>\u0000 crystal lattice. Here the mechanical properties of cycled SC NMC811 particles are evaluated in real time using in situ compression in a scanning electron microscope (SEM), as a function of both particle orientation, and electrochemical charge-discharge rate. After 100 cycles, the SC NMC811 particles retain their external morphology, however their non-basal and basal plane fracture strengths systematically decrease as a function of increasing charge rate C/10→2 C, consistent with accelerated lattice degradation. For all charge rates, the cycled and discharged NMC811 single crystal particles retain the <math></math>\u0000 crystallographic dependence of their strength and deformation mechanisms, with cycled SC particles strongest for compression normal to the (0001) layered structure. The accelerated mechanical softening of cycled NMC811 SC particles at higher C-rates occurs in parallel with degradation of the electrochemical performance of the NMC811 single crystals, and indicates a higher risk of fracture-related degradation processes with fast-charging regimes.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 6","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400691","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although cathode coated with a thin layer of LiNbO3 provide higher interface stability, which significantly improves charge-discharge and cycle performance, degradation at high potentials has also been noted. In this study, we focused on the degradation mechanism of LiNbO3-coated LiNi0.5Co0.2Mn0.3O2 cathode active materials at high potentials by using three electrode system for ASSBs, which allows separating the impedance measurement of the interface between cathode and solid electrolyte. We performed X-ray absorption spectroscopy (XAS) measurements at low temperature (10 K) to analyze the local structure around Nb and correlate these findings with impedance measurements. Our results indicate that the impedance of LiNbO3 increased rapidly due to the oxygen desorption reaction at high potentials.

Aqueous hybrid supercapacitors (AHSCs) have garnered attention due to their advantageous characteristics, including low cost, safety, reliability, and high cyclic stability. Here, this review provides a brief overview of the energy storage mechanisms of double electric layer capacitors (EDLCs), pseudocapacitors, and hybrid supercapacitors (HSCs), which combine the features of both of these types of capacitors. The progress made in recent years in research on AHSCs using multivalent metal cations, including manganese, zinc, and chromium, is highlighted. Additionally, some examples of AHSCs assembled with the participation of metal ions are summarized based on the metal activity series. Furthermore, the potential use of other multivalent metals, including iron, cobalt, nickel, and copper, in AHSCs electrodes was explored, as well as the current status of aqueous ammonium-ionized HSCs, with a focus on their respective advantages and challenges.

NiCo2O4 with various oxygen vacancy levels was synthesized via an ethylene glycol-assisted solvothermal route. This resulted in significant changes in the structural and morphological properties, such as reduced crystallite size, lattice distortion, and increased oxygen vacancies, as observed from the physicochemical results. This was further verified by X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HR-TEM), which showed a homogeneous dispersion of nickel cobaltite nanorods on the carbonaceous matrix, along with an increased concentration of pyridinic nitrogen and the formation of P−N and P−C bonds, both of which enhance electrocatalytic activity.

However, the practical application of these materials faces challenges such as poor conductivity and volume expansion. To address these issues and enhance the performance of LIBs, it is crucial to tackle the structural design problem associated with ZnxInyS anode material. The utilization of metal sulfides derived from metal-organic frameworks (MOFs) not only improves conductivity but also mitigates the issue of volume expansion in metal sulfides. Furthermore, connecting the metal sulfides derived from MOF to various conductive substrates can further enhance their conductivity. Two-dimensional transition metal carbides and nitrides (MXenes), a novel type of 2D material with plentiful functional groups and chemical properties, offer great potential. In this study, we have strategically constructed ZnxInyS/MXene heterostructures by combining the advantages of 2D Ti3C2TX nanosheets and bimetallic MOF structures.
