Summary: The commonly used Ag/AgCl wire quasi-reference counter electrode in the quantitative scanning micropipette contact method may leak Ag+ into the electrolyte solution, leading to interference in potential and generation of faradaic current. By using a leak-free Ag/AgCl electrode or increasing the distance between the electrode and micropipette tip droplet, the contamination of Ag+ can be eliminated, allowing accurate measurement of corrosion potentials during oil-immersed scanning micropipette contact method measurements.

Summary: This study provides insights into the structure and behavior of the electrified interface between a planar non-porous glassy carbon electrode and a 0.5 M Na2SO4 aqueous solution. By using a rotating glassy carbon disk electrode, it is observed that increasing rotation rates lead to decreasing boundary layer thicknesses and interfacial capacitance. This suggests that electrolyte counter charge extends significantly into the electrolyte due to the dissipation of counter charge through convective flow outside the macroscopically thick boundary layer.

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.

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.
