In the past years, the number of publications on practical prototype cells have increased, already reporting high specific energies over 400 Wh kg−1 with low electrolyte-to-sulfur (E : S) ratios. To enable the complex conversion chemistry at low E : S ratios, the cathode porosity adaption is crucial and depends for example on the suspension blending procedure. There are several methods and devices to prepare suspensions for battery electrodes, e. g. dissolver and planetary mixers. In this study, a standard laboratory blender with low shear forces (EL1) is compared with a high shear mixer (HSM) for preparing porous carbon-sulfur suspensions in a relevant scale. In this study, the influence of the slurry preparation on the final performance is investigated by coating via slot die on a roll-to-roll device to produce carbon-sulfur-cathodes. The electrodes are characterized via optical and mechanical measurements. Electrochemical analysis is conducted using coin cells for pre-evaluation as well as multi-layered pouch cells with reduced electrolyte volume (3.0 μl mg(S)−1). It could be shown that the HSM enables increased binder dispersion and enhanced density leading to improved cycle life.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 8","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400768","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144809280","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}

While increasing the nickel content increases the available capacity in a given voltage window, it also reduces the structural stability of the material when cycled to high cutoff voltages. Oxygen release from the crystal structure as well as a layered-to-rocksalt phase transformation of the layered oxide material cause capacity loss and impedance rise. In this work, we propose a continuum approach to model oxygen release and the associated phase transformation using a 1+1D model informed by atomistic simulations to predict the thickness of reconstructed active material over time. An efficient interface model allows us to combine this approach with 3D microstructure-resolved simulations in order to study the effect of a resistive layer on a real cathode microstructure. This novel workflow enables us to investigate the effect of individual electrode properties on the phase transformation and guide future electrode design.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 8","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/batt.202400802","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144811403","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}

Here, we select the oligopeptide of mono-, di-, tri-, and tetra-glycine, as electrolyte additives to optimize the Zn2+ solvation microenvironment in AZIBs. Contrary to traditional views, we find that these additives modify the solvated structure of the Zn2+ by substituting sulfate ion (SO42−) in the preexistence of Zn2+-SO42− ion pair, rather than water molecules in the first solvation shell, due to a high energy barrier to replace one of the coordinated water molecules of Zn2+. This observation is consistent with recent experimental result of the attenuating influence of glycine on the interaction between Zn2+ and SO42− confirmed by Fourier-transform infrared spectroscopy. For the multifunctional triglycine, its favorable conformation is disrupted to accommodate the direct coordination of oxygen atoms with Zn2+, and Zn2+ is observed to migrate between distinct sites along the triglycine backbone. This work provides theoretical principles to rationally design advanced electrolytes for solvation modulation with high performance AZIBs.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 7","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional methods for Ni-rich cathodes are energy-intensive, taking up to 24 hours, which increases costs and CO2 emissions. In contrast, this study introduces a Co-free Ni-rich layered oxide cathode (LiNi0.9Fe0.05Al0.05O2 (NFA)) synthesis using a rapid microwave heating technique. This method takes just 2.5 hours, including heating and dwell time, while consuming minimal electricity. The microwave-annealed cathodes exhibits a well-ordered layered structure with fewer defects compared to those produced by traditional calcination (21 h). Furthermore, these cathodes display superior discharge capacities across all C-rates (e. g. 157 mAh g−1 at 1 C-rate and 129 mAh g−1 at 10 C-rate) and retain 78.1 % specific capacity after 100 cycles at high current density (1 C-rate).

However, the formation of surface residual impurities and extreme sensitivity to moisture are detrimental to the large-scale synthesis and electrochemical performance of NCA. This paper investigates the formation of Li2CO3 surface impurities and the elemental distribution of lithium within the secondary particle in NCA synthesized with different lithium-to-transition metal ratios. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy confirm the presence of Li2CO3 on the surface of NCA prepared with 3 % excess lithium. Atom probe tomography (APT) analysis of the particle interior confirms the absence of carbonaceous products within the hierarchical structure. Instead, it reveals the segregation of lithium ions into discrete regions, which leads to the poor electrochemical performance of NCA synthesized with excess Li. Upon storage, the structural and electrochemical deterioration is more pronounced in NCA with a 3 % excess of lithium than the one prepared without excess lithium, as confirmed by XRD, Raman imaging, and electrochemical galvanostatic charge-discharge testing.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"8 8","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144811038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high upper cut-off voltage could cause severe side reactions and injure the cycle life of SIBs as the absence of stable cathode-electrolyte interface. Some fluorinated co-solvents have been ever employed and proven effective in stabilizing the cathode-electrolyte interface to support the normal operation of SIBs under a high upper cut-off voltage. However, the high-cost of fluorinated co-solvents would notably improve battery expenses. In this study, a low-cost co-solvent called ethyl methylsulfone (EMS) is introduced into the electrolyte for the Na0.67Mn0.8Cu0.2O2 cathode with a high upper cut-off voltage of 4.5 V. It is found that a stable and uniform cathode-electrolyte interface (CEI) forms on the cathode, which mitigates the cathode degradation and enhances the cycling stability of cathode. Consequently, this cathode with the designed electrolyte achieves a high capacity retention of 83.2 % after 750 cycles at a current density of 1 C (1 C=110 mAh g−1).

The conductive network constructed by interconnected CNTs ensures an optimal electric field distribution over the entire electrode surface. The embedded brass alloy not only inhibits the aggregation of CNTs, but also mitigates surface corrosion through its abundance of chemically inert Cu sites. Leveraging the synergy within the carbon hybrids featuring high Zn-affinity and abundant nucleation sites for Zn2+, lowered energy barriers and promoted redox kinetics for Zn deposition enable highly stabilized and reversible Zn anodes. As a result, symmetric cells demonstrate extended cycling lifespan of 3000 h and 1200 h at 2 mA cm−2 and 5 mA cm−2 for 1 mAh cm−2, respectively.
