Summary: The effect of different carboxylic acid substituents on the electrochemical performance of polythiophene anode materials was discussed. Isophthalic acid substituted polythiophene (P3TBDCOOH) outperforms formic and parabenzoic acid substituted polythiophenes (P3-TCOOH and P3-TBCOOH) in terms of cycle and rate performance. P3-TBDCOOH exhibits higher conductivity than P3-TBCOOH and P3-TCOOH due to the presence of a benzene ring between the thiophene ring and the carboxyl group. The results suggest that pendant isophthalic acid can enhance the electrochemical activity of polythiophene, increasing the reversible capacity.

Summary: All-solid-state batteries (ASSBs) with sulfide solid-state electrolytes (SEs) offer high conductivity and are promising candidates for next-generation energy storage. This study reveals two distinct thermal runaway mechanisms of sulfide-based ASSBs, namely gas-solid and solid-solid reactions. The gas-solid reactions cause tremendous heat and toxic SO2 gas generation, while the solid-solid reactions show stable behavior without SO2 generation. This research provides fundamental insights into the safety of ASSBs and offers new design principles for intrinsically safe batteries using emerging materials.

Summary: Coordination polymers (CPs) with multiple redox-active sites have great potential as rechargeable lithium batteries due to their adjustable composition, pore structure, crystalline nature, and easy synthesis. The crystalline structures provide abundant accessible redox-active sites and three-dimensional channels for rapid ion transport. This review summarizes the design strategies of CP-based materials for lithium-ion storage and ion transport in rechargeable lithium batteries. The improved electrochemical performance of CPs in lithium batteries is closely related to favorable working mechanisms, synergistic redox-active reactions, addition of conductive molecules, and well-designed porous structures or morphologies. The opportunities and challenges of applying CPs to lithium-ion storage and ion transport are also discussed.

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.
