This study reports first-principles predictions as well experimental synthesis of manganese oxide nanoparticles under different conditions. The theoretical part the work comprised density functional theory (DFT)-based calculations and molecular dynamics (MD) simulations. extensive research efforts current challenges in enhancing performance lithium-ion battery (LIB) provided motivation to explore potential these materials for use an anode battery. structural analysis synthesized samples carried out using X-ray diffraction (XRD) confirmed tetragonal structure Mn3O4 on heating at 450 550 °C cubic Mn2O3 650 °C. structures are found form °C, but material appeared a nanoporous structure. Further, we investigated electrochemical functionality utilization LIBs via MD Based investigations their electrical, structural, diffusion, storage behavior, anodic character is predicted. findings indicated that 10 lithium atoms adsorb Mn2O3, whereas 5 when saturation taken into account. capacities estimated be 1697 585 mAh g–1, respectively. maximum value insertion voltage per Li 0.93 0.22 V Mn3O4. diffusion coefficient values 2.69 × 10–9 2.65 10–10 m2 s–1 Mn3O4, respectively, 300 K. climbing image nudged elastic band method (Cl-NEB) was implemented, which revealed activation energy barriers 0.30 0.75 eV high specific capacity, low barrier, open circuit Mn2O3-based LIBs.

With the increasing demand for renewable energy worldwide, lithium-ion batteries are a major candidate shift due to their superior capabilities. However, heat generated by these during operation can lead serious safety issues and even fires explosions if not managed effectively. Lithium-ion also suffer from significant performance degradation at low temperatures, including reduced power output, shorter cycle life, usable capacity. Deploying an effective battery thermal management system (BTMS) is crucial address obstacles maintain stable within safe temperature range. In this study, we review recent developments in transfer of Li-ion offer more effective, secure, cost-effective solutions. We evaluate different technologies BTMSs, such as air cooling, liquid phase change materials, pipes, external preheating, internal discussing advantages disadvantages. Through comparative analyses high-temperature cooling low-temperature highlight research trends inspire future researchers. According literature, submerged BTMS configurations show greatest potential focus enhance regulation batteries. addition, there considerable innovation air-based optimization liquid-based coupling pipes with PCMs, integration PCMs liquid-cooled hybrid application machine learning topology design. The 3D printing promises efficiency adaptability through design innovative materials structures, thereby improving battery’s safety.
