Abstract: Energy storage has become an essential aspect of modern energy processes, with a particular focus on enhancing the performance of thermal devices such as lithium batteries, which are widely regarded as a key technology in the transition to electric vehicles. In instances where the placement of heat removal systems is necessary to prevent the device from heating up, this paper study the storage capacity of a bioorganic phase-change material (PCM) encapsulated in silica nanoparticles. This PCM is obtained from sodium silicate (MS) and its modification with magnetite (MS-Fe3O4). The PCM was integrated into the silica matrix through impregnation, and infrared spectroscopy demonstrated the presence of its primary functional groups. Furthermore, thermal characterization curves were obtained, indicating a significant impact on the temperature holding time when the PCM was absorbed into the silica matrix modified with magnetite.
