Abstract

As we progressively transition from conventional energy sources to more sustainable and renewable alternatives, the emergence of electric vehicles (EVs) in the market stands as a promising step towards strengthening energy security and reducing carbon emissions. The utilization of lithium-ion (Li-ion) batteries, known for their high energy density and extended cycle life, has become widespread in the realm of electric cars. Among various approaches to battery thermal management, the implementation of phase change materials (PCMs) holds significant promise, offering a more reliable solution compared to traditional active and passive cooling methods. The development of PCM-based battery thermal management systems (BTMS) presents its own set of challenges, primarily restricting from the inherently limited heat conductivity of these materials and the complexities associated with their modelling. This study paper is dedicated to addressing a pivotal objective: providing comprehensive insights into the modulation of thermal conductivity in PCMs through the incorporation of Nanoparticles. Additionally, this paper delves into different facets of Li-ion batteries and the integration of nano-enhanced PCMs.
