Abstract

This study aims to evaluate the thermal performance of Phase Change Material (PCM) composites based on paraffin wax. However, the use of paraffin alone as PCM has a drawback in terms of low thermal conductivity. To enhance the thermal conductivity of the PCM, additional elements need to be incorporated into the paraffin. Bamboo carbon, especially that produced through carbonization processes, holds great potential in various applications, including as a thermal energy storage material (PCM). The carbonization of bamboo at high temperatures produces materials with porous structures that can improve energy storage capacity. The use of bamboo carbon in energy storage systems not only provides a solution for renewable energy needs but also supports environmental sustainability by utilizing abundant and renewable natural resources Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), and Derivative Thermogravimetry (DTG) tests were conducted on PCM materials with varying bamboo carbon concentrations of 0%, 5%, 10%, and 15%. The test results showed that the addition of bamboo carbon influences the melting temperature, melting enthalpy, and thermal stability of the PCM. The sample containing 10% bamboo carbon exhibited the highest melting enthalpy value of 104.99 kJ/kg, which has the potential to enhance heat storage capacity and improve the cooling efficiency of electric vehicle batteries.
