Summary: Cr-doped and undoped lithium zinc titanate (LZTO) was prepared using a high-temperature solid-state ball-milling method, and the effect of Cr doping was investigated. The results showed that Cr3+ doping did not cause changes in the lattice structure and could reduce particle size and agglomeration. The Cr-doped samples exhibited better electrochemical performance than the pristine LZTO, with Li2ZnCr0.3Ti2.7O8 showing the highest discharge capacity, better cyclability, and lower polarization. The electrochemical impedance spectroscopy revealed that Li2ZnCr0.3Ti2.7O8 had lower charge-transfer resistance and faster Li-ion diffusivity, making it suitable as an alternative anode for lithium-ion batteries.

Summary: Niobium-based anode materials show promise for use in lithium-ion batteries due to their high specific capacity and safety. However, their low electronic conductivity limits their performance. In this study, a mixed-valent niobium-based phosphate, K3Nb6P4O26@C, was developed as an anode material. The mixed-valent Nb in KNPO enables multi-electron reactions and higher electronic conductivity. The 3D channels in the crystal structure of KNPO facilitate rapid lithium-ion transport. KNPO@C anode demonstrates a high specific capacity and excellent cycling stability, making it a potential practical material for high-performance LIBs.

Summary: This study systematically investigates the role of transition metal-functionalized N-doped carbon nanosheets as multifunctional electrocatalyst supports for hydrogen evolution/oxidation reactions in alkaline media. The results show that all the M-N-C nanosheets, except Cu-N-C and Ag-N-C, can promote the alkaline HER/HOR electrocatalytic activity of Pt, with Mn playing a more significant role. The promotion effect of the M-N-C support is closely associated with the electronegativity of the metal dopants and the filling degree of their d-orbitals.

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.
