“…So, it requires encapsulation of PCM. This weakness of material depending on its nature can be improved using different methods investigating by researchers including increasing the heat transfer area (Aydin et al, 2018), geometric optimization (Yazici et al, 2014), dispersing particles (Arshad et al, 2020), metal matrix (Alhusseny et al, 2020), impregnated graphite foam/matrix (Py et al, 2001), encapsulation (Zhang et al, 2021).…”

An experimental study is performed to investigate the performance (thermally and electrically) of a small-scale li-ion module (3s2p) using passive thermal management strategy of phase change material (PCM)/graphite matrix. The PCM/graphite matrix was obtained by impregnating the graphite matrix (bulk density: 75 g L-1) with phase change material (paraffin/organic, RT-35). The performance tests of a li-ion module are conducted at 1C and 1.6C discharge rates for graphite matrix composite with phase change (phase change composite or PCM/graphite matrix) and also air cooling, comparatively. To illustrate the performance of the PCM/graphite matrix, transient temperature variations, thermal imaging, discharge capacity, and energy capacity are achieved comprehensively. The results illustrate that graphite matrix composite with phase change has a significant contribution to melting heat transfer, operating temperature, utilized capacity, and energy capacity compared to air cooling. Effective thermal conductivity of PCM/graphite matrix is increased 35 times by comparison with pure paraffin. Operating temperature and temperature gradient throughout the li-ion surface decrease by 22 % and 43 % compared to the air cooling, respectively, for high discharge rate. Operating time and energy capacity is increased 33 % and 28% compared to natural air cooling, respectively, for high discharge rate. It is also disclosed that dominant heat transfer mechanism is conduction depending on micro/nano-size porous structure of graphite matrix.

“…Likewise, during solidification, the change in aggregate state of the PCM takes place starting from the outer surfaces of the capsule, preventing the stored heat from being effectively released to the environment. According to the works [ 4 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ], the improvement of the efficiency of heat distribution within PCM packages can be achieved by using in their structure a material that conducts heat well, such as copper [ 11 , 12 , 14 ], aluminum [ 13 ], or graphite [ 10 ].However, due to their high price and high carbon trace, the secant be replaced with other, more ecological substances at least in part from recycling.…”

The article presents the results of experimental research together with the development of a response function presenting the thermal functioning of a new composite of a phase change material with carbon recyclate. The empirical research proved the improvement of the thermal functioning of the phase change material as a result of modifying its structure with carbon-based recycling material. The conducted experimental tests and statistical analysis proved that the obtained innovative composite is characterized by a more effective distribution of stored heat than the pure phase change material, which resulted in reduction of the heating and cooling time of the package by 10 min. The obtained innovative composite can improve the thermal efficiency of short-term heat storage systems, both in building components and in elements of heating and cooling systems, and translates into their increase in thermal efficiency.

“…For example, Al-Mudhafar et al 18 designed a webbed tube heat exchanger to increase the latent heat thermal energy storage capacity of MPCMs. Besides, as the thermal conductivity of pure PCMs is usually low to impede the heat transfer capacity in the MPCM structure, high thermal conductivity materials, such as metal foam, 19 graphite, 20 graphene oxide, 21 carbon fiber sheet, 22 Ag doped ZnO materials, are usually considered to be added into the MPCMs. 23 Dong et al 22 found that a 14.4% (in volume) carbon fiber sheet can improve the effective thermal conductivity of the MPCM composite by 24.4 W m −1 K −1 .…”
