Abstract

Lithium-ion batteries are fundamental to modern electric vehicles, offering high energy density, long cycle life, and low self-discharge rates. However, thermal runaway—a critical safety issue involving uncontrolled temperature increases—can lead to fire or explosion. Ensuring flame retardancy is crucial in accidents where battery packs are exposed to external fires. Additionally, battery packs are susceptible to mechanical stresses and potential damage from ground impacts like debris or uneven road surfaces. Effective thermal management significantly impacts capacity and longevity. This review emphasizes the importance of researching flame retardancy, ground impact resistance, and thermal management, especially in composite battery enclosures. Composites serve as a lightweight alternative to metals and help overcome one of the main constraints of EVs, which is weight. Ground impact refers to the physical force battery packs endure during collisions, hitting potholes, debris, or accidents. Therefore, understanding the effects of ground impact on battery enclosures is crucial for design considerations. Effective thermal management is also essential, as it directly affects the performance and safety of Lithium-ion battery packs in EVs.

Abstract

The increasing demand for sustainable and lightweight materials in the transportation sector, particularly in the context of electric vehicles (EVs), has accelerated the exploration of bio-based composites as viable alternatives to conventional structural materials. This study investigates the mechanical performance of hollow structural components fabricated from polylactic acid (PLA)-based composites reinforced with natural ramie fibers, targeting their application as chassis elements in urban electric vehicles. Emphasis is placed on replacing commercial steel hollow sections with environmentally benign alternatives that maintain mechanical integrity while offering additional functional benefits such as electrical non-conductivity. Three-point bending tests were conducted to evaluate the composite specimens' flexural strength, stiffness, and failure behavior to assess structural viability. This method was selected for its relevance to real-world bending stresses encountered in vehicular chassis components and suitability for consistent evaluation across beam-like geometries. Results demonstrate that the ramie-PLA bio-composite exhibits promising flexural performance, with sufficient bendability and stiffness for potential structural integration. Furthermore, the non-conductive nature of the composite presents a significant advantage for reducing electromagnetic interference with sensitive electronic systems common in EV platforms. The findings support the feasibility of deploying natural fiber-reinforced PLA composites as a sustainable, cost-effective solution for lightweight automotive structures, particularly in emerging markets where urban EV adoption is rapidly expanding.
