Summary: Single-crystal NCMs are considered promising cathode materials for next-generation lithium batteries due to their good cyclability and high safety. However, industrial production of single-crystal NCMs faces challenges of lengthy production steps, high production costs, and poor consistency. In this study, a Ni-Co-Mn ternary MOF was developed for the preparation of NCM cathode materials, which exhibited high activity and could be used to prepare single-crystal NCM111 (SC-NCM) through a regular sintering process. The as-prepared SC-NCM cathode materials showed a polyhedral structure with a smooth surface and demonstrated excellent cyclability and high specific capacities as a high-voltage cathode.

Summary: Honeycomb-layered oxides with monovalent or divalent, monolayered cationic lattices have diverse crystalline features and are attractive for next-generation energy storage applications. This study investigates the composition and properties of global honeycomb-layered oxides, specifically Ag2M2TeO6 (M=Ni,Mg,etc), which exhibit Ag atom bilayers with sub-valent states within Ag-rich crystalline domains and Ag-deficient domains. The material shows high ionic conductivity and oxygen-hole electrochemistry during silver-ion extraction, and the bilayered structure and sub-valent states are theoretically understood by spontaneous symmetry breaking of SU(2)x U(1) gauge symmetry interactions. These findings suggest that bilayered frameworks have research applications beyond energy storage.

Summary: Layered P2-type Na containing manganese-nickel oxide (Na-2/3(Mn2/3Ni1/3)O-2) materials exhibit higher electrochemical capacity. The cycling performance of Na-2/3(Mn2/3Ni1/3)O-2 can be improved by reducing crystallite size and introducing defects at transition metal site, which restrict the structural changes. In addition, the metal defects enhance the contribution of oxygen redox without causing overpotential and capacity fading during cycling.

Summary: We evaluated the levels of anti-spike immunoglobulin G (anti-S-IgG) in healthcare workers (HCWs) after receiving the BNT162b2 vaccine. The titers of anti-S-IgG were measured every three months before and after each vaccination. This study compared the short-term immune response to the second vaccination in two groups of HCWs, with one group receiving the first two doses six months apart due to allergic-like adverse events after the first dose. Four HCWs in this group took antihistamines before the second vaccination and did not experience allergic reactions. The short-term immune response to the second vaccination was similar in both groups.

Summary: This study investigated the charge and discharge behavior of a low-crystalline VS4 positive electrode using different electrolytes and under differing charge and discharge conditions. The electrolyte composed purely of cyclic carbonate displayed higher cycle performance than the one containing linear carbonate. Addition of fluoroethylene carbonate (FEC) to the electrolyte effectively improved the cycle performance. The results showed that LiF-containing components were formed on the VS4 surface, which contributed to the improvement of the charge and discharge behavior of the VS4 positive electrode.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
