) foam combined with nonadecane to regulate the temperature of a 21,700 lithium-ion battery during discharge. Five configurations with varying porosity levels were analyzed for different C-rates using the Finite Volume Method (FVM). Thermal behavior was assessed based on average and maximum temperatures and the liquid-to-total ratio (LTR%) within the housing. Results show that decreasing porosity enhances heat transfer due to improved thermal conductivity from increased surface area. The configuration with ε = 0.92 demonstrated superior performance by reducing thermal buildup and distributing temperature uniformly along the battery. Additionally, a Thermo-Techno-Economic Assessment (TTEA) was conducted for a 50-cell battery pack using this configuration across various C-rates. Net Present Value (NPV) analysis revealed that the proposed system offers improved economic viability at higher C-rates compared to traditional air-based cooling methods.
This study involved connecting four 18650 cylindrical lithium-ion batteries in series. An ABS structure produced using a 3D printer was then filled with salt hydrate phase change material (PCM). The batteries were then tested in two separate systems: one containing PCM and one without. In the PCM-enhanced system, the m...

Lithium-ion batteries (LIBs) typically operate within a temperature range of 20–50 °C, depending on the chemical composition and application of the battery. Overheating may lead to degradation and thermal runaway, while overcooling may cause lithium plating and internal short circuits. Absorbing heat during the melting...
