Summary: The study synthesized four different MnO2 polymorphs with controlled morphology to investigate their influences in conversion-based materials. Experimental results showed that spinel-phased MnO2 was formed during charge storage reactions for all samples, but the electrochemical performance varied based on the initial crystal structure. Among the polymorphs, lambda-MnO2 exhibited the highest reversible capacity of around 1270 mAh g(-1) due to its faster kinetics and structural similarity between cycled and pristine states. These findings suggest that polymorphs are an important factor in designing high-performance materials for next-generation rechargeable batteries.

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.
