Efficient and secure operation of electric vehicles relies significantly on the cooling system for lithium iron phosphate (LiFePO4) batteries, a key component in electric vehicle technology.. One of the critical challenges faced by electric vehicle is battery cooling to ensure optimal performance, extended battery life, and enhanced safety. The excessive heat generated during battery operation can lead to decrease in performance and potential safety hazards. Conventional cooling systems, such as air or liquid cooling, have limitations in terms of their cooling capacity, weight, and complexity. Therefore, there is a need to explore innovative cooling techniques that can effectively reduce the thermal issues associated with Electric Vehicles LiFePO4batteries. Employing a thermal insulating coating and phase change material at the critical thickness emerges as an innovative approach to mitigate the surface temperature of battery cells. This is evident during the charging phase, where the bare cell, Teflon-insulated, and paraffin wax-coated cells reached respective peak temperatures of 69 ˚C, 57 ˚C, and 53.3 ˚C. Notably, the Teflon-coated cell exhibited a 17.39% reduction in peak temperature compared to the bare cell, while the paraffin wax-coated cell displayed a more substantial 23.18% reduction. A similar temperature reduction trend is observed during the discharging phase of the battery cell. Utilizing insulating materials or phase change materials with a critical thickness significantly lowers surface temperatures, enhancing the safety of the battery cell and ensuring prolonged life.

“…The increase in thermal conductivity, especially of organic phase-change materials, is one of the leading scientific issues related to their use in construction. In different contributions, conventional thermal conductors, such as copper or aluminium enclosures or foams [ 21 , 22 ], nano-mixes of carbon or graphite glass fibres, fullerenes, activated carbon [ 23 , 24 ], nanoparticles of transition metal oxides, e.g., titanium oxides TiO 2 , as described in [ 25 ], or using nano-liquid PCM systems, as described in [ 26 , 27 ], are used to enhance heat distribution within a solid PCM. An interesting example of increasing the efficiency of heat transfer within the PCM is the bionic system discussed in [ 28 ], based on the hierarchical arrangement of convective heat transfer channels between PCM granules.…”

This paper presents the long-term, holistic results of research into an innovative heat accumulator based on an organic phase-change material in the form of a mixture of aliphatic alkanes, molecular silica sieves, carbon recyclate and epoxy and cement matrices. The research included chemical testing of vacuum soaking of molecular silica sieves with a liquid phase-change material. The results proved an improvement in the heat storage efficiency of the heat accumulators due to the addition of carbon recyclate by 28%, while increasing the heat storage time by 134 min, and a reduction in PCM leakage due to the use of molecular silica sieves. In addition to its cognitive scientific value, another research objective of the work achieved was to obtain response functions in the form of approximating polynomials. They provide a useful, validated and verified tool to predict the physical and chemical characteristics of heat accumulators with different contents of individual components. As part of the ongoing research, technical problems related to leak-proofing assurance and matrix selection for organic phase-change materials were also solved. The solution presented is in line with the issues of efficient use of renewable energy, low-carbon and energy-efficient circular economy.

Partial storage strategy can save energy and reduce emissions. In this study, analysis of the partial melting process of ice inserted with nanoparticles inside a square enclosure is investigated for thermal energy storage. The lattice Boltzmann method is for melting and heat transfer in the storage unit. The validation demonstrates strong concurrence between the current findings and the experimental data documented in the literature. The analysis is performed for various Rayleigh numbers, nanoparticle volume fractions, and their effect on melting time and energy storage. Two types of nanoparticles are tested that is, copper and alumina. The outcomes indicate that the Rayleigh number and volume fraction of nanoparticles have a significant impact on the phase change process. The nanoparticles addition leads to homogenous and hence expedited melting process including the final stage of the ice melting process which is very slow without nanoparticles. Furthermore, copper nanoparticles are slightly more effective than alumina. Moreover, using 6% copper nanoparticles can reduce the melting time by up to 12.4%.
