Summary: In recent years, MXenes and its precursor MAX phases have been extensively studied in electrochemical research. In this study, a core-shell structured compound, Ti3C2@Ti2SnC/CNFs (MXene@TSC/C), was successfully prepared as an anode material for lithium-ion batteries using the electrospinning method. The compound exhibited a specific capacity of 288.9 mAh·g-1 at a current density of 0.4 A g-1 after 300 cycles, with a capacity retention rate of 105.4% in rate performance tests. These enhanced performances were attributed to the core-shell structured CNFs and Ti3C2 MXenes. This work provides a novel approach to improving the electrochemical properties of MXene and MAX phases, with further exploration expected.

Summary: We synthesized TiO2-SnO2-C/carbide hybrid electrode materials for Li-ion batteries (LIBs) by oxidizing layered Ti2SnC using two different methods. The oxidized materials were tested as an anode in a half cell for their electrochemical performance in LIBs. The highest initial lithiation capacity of 838 mAh/g was achieved with the sample oxidized in an open-air furnace at 700 degrees C for 1 h, but the delithiation capacity dropped to 427 mAh/g over cycling. Long-term cycling showed that the sample treated with rapid thermal annealing at 800 degrees C for 30 s exhibited the most efficient performance with a reversible capacity of around 270 mAh/g after 150 cycles and a specific capacity of about 150 mAh/g under high cycling rate (2000 mA/g).

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.
