【Abstract】 As an important component of new energy vehicles, the safety and protection of automotive power batteries are crucial for the development of new energy vehicles. The development of cushioning packaging materials for pouch battery cells can not only effectively enhance the safety of batteries and reduce the risk of damage during transportation and use, but also contribute to the widespread application and market acceptance of new energy vehicles. This article provides an overview of the types and characteristics of cushioning packaging materials for pouch battery cells, and comprehensively reviews aspects such as flame retardancy, heat insulation,lightweight design, and environmental friendliness of these cushioning packaging materials for pouch battery cells.Finally, the existing problems of cushioning packaging materials made of plant fibers for battery cells are summarized, and the future development directions are prospected. Although cushioning packaging materials made of plant fibers for battery cells perform excellently in aspects such as cushioning, shock absorption, and temperature resistance, it is still necessary to further improve the mechanical properties and flame retardant and heat insulation properties of the materials, and to perfect their preparation processes.更多还原
