The mechanical resonance, activated at a specific frequency, allows the electrolyte to infiltrate the porous separator through capillary waves and inertia force. This mechanical method, rather than electrochemistry, contributes to the higher specific capacity, rate capability, and cycling stability of LIBs, providing a promising strategy for developing safer LIBs with liquid electrolytes.

Summary: A computational study was conducted on natural convection around a cylinder with multiple lateral baffles in a square enclosure. The study found that the average Nusselt number on the cylinder surface is mainly dependent on the distance between the hot and cold surfaces and that a larger cavity spacing leads to greater heat transfer. A new average Nusselt number correlation was proposed based on the presence or absence of lateral baffles on the cylinder surface. The contribution of vortices in the enclosure to the Nusselt number was also assessed using Q-criterion analysis.

Summary: Numerical case studies were conducted to investigate natural convection in triangular and hexagonal enclosures, following a previous study on natural convection in a baffled cylinder in a square enclosure. Different length ratios and Rayleigh numbers were considered, and the Boussinesq approximation was used to model buoyancy force. The heat transfer performance showed conduction- and convection-dominated regimes, with the triangular enclosure exhibiting advantages in convection due to its wider space. The hexagonal enclosure had a higher conduction-dominated characteristic due to the shorter distance between the cylinder and enclosure. The location of the high-energy vortex was found to correlate with the Nusselt number distribution, leading to the proposal of an improved average Nusselt number correlation for triangular, square, and hexagonal enclosures.

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.
