Summary: Recent studies have found that Ti-based MXene shows great potential for electrochemical energy storage applications, but poor electrochemical properties due to self-stacking and weak interlayer interactions. A MXene/CMC/CNT hybrid membrane was prepared using a one-step vacuum filtration method. The CMC and CNT formed an interconnected mesh structure, mitigating self-aggregation of CNT and imparting electrical conductivity. The CMC and CNT tightly anchored to Ti3C2Tx nanosheets, forming a complete conductive pathway. The resulting Ti3C2Tx/CMC/CNT hybrid film exhibited a maximum tensile strength of 64.9 MPa. Additionally, an asymmetric micro-supercapacitor (MSC) using Ti3C2Tx/CMC/CNT as the cathode and RGO/CMC/PPy as the anode demonstrated a high energy density of 258.8 μWh/cm2 and an ultra-long cycle life of 93.2% capacitance retention after 15,000 cycles. The simple and scalable preparation process makes this MSC device highly promising for commercial electronics applications.

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.
