Summary: This study investigates the impact of conjugate and non-conjugate boundary conditions on the heat transfer characteristics of battery packs. Numerical analysis reveals that temperature distribution is more uniform under non-conjugate conditions compared to the symmetrical nature indicated. Maintaining a proper balance of thermal conductivity between solid and fluid domains is crucial for preventing uneven thermal stresses in battery packs.

Summary: In this study, the heat flow behavior of (Ni1/3Co1/3Mn1/3)O-2 (NCM) and LiFePO4 (LFP) batteries during discharge and charge cycles at different ambient temperatures and discharge rates was investigated using a high precision isothermal microcalorimeter (TAM IV) for the first time. The results showed that low temperatures had a greater effect on the heat flow of the batteries. Furthermore, NCM batteries exhibited higher thermal stability during heating and cooling, as well as with increasing discharge rates. The research provides practical insights for the application, monitoring, and optimization of lithium-ion batteries.

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: The influence of magnetic dipole on the flow of a Maxwell hybrid nanoliquid over a stretching sheet with a non-uniform heat source/sink is examined in this study. The effects of non-dimensional parameters on the fluid profiles are explained graphically, showing that the radial velocity increases with higher Maxwell parameter values and decreases with higher ferromagnetic interaction parameter values. The rising values of space and temperature dependent heat source/sink parameters improve the heat transfer.

Summary: The present research investigates the transient temperature distribution in a moving plate with exponentially temperature-dependent thermal conductivity and heat transfer coefficient. The study finds that the transient thermal distribution decreases significantly with an increase in the convection-conduction parameter and the same trend is observed for the radiation-conduction parameter. Furthermore, the results demonstrate that the transient thermal distribution through a moving plate enhances gradually as the plate moves faster.

Summary: In this paper, the usefulness of flow control in recirculation and flow growth in a supersonic tube is quantified for different levels of expansion and tube lengths. The results show that flow control management has an effect on the flow pattern, with oscillatory flow fields and control reversal phenomena observed in longer ducts. However, for shorter ducts, no such phenomena are seen. The study also finds that flow control has different outcomes at different Mach numbers, with pressure decrease and increase observed in under-expanded and over-expanded flow, respectively.
