Enhancing Battery Performance and Safety Through Nanomaterial Coatings

The global transition to electric vehicles (EVs) is crucial for reducing carbon dioxide (CO₂) emissions and combating climate change. Although EVs offer environmental and economic advantages, battery performance challenges such as electrode degradation and electrolyte decomposition hinder their widespread adoption. This paper investigates the use of nanomaterials in battery coatings and membranes to improve EV battery performance and lifespan. Conductive polymers like Polyaniline (PANI), carbon-based materials such as g-C₃N₄/CNTs, and α-Fe₂O₃@C are explored for their capacity to enhance electrode stability, electrical conductivity, and specific capacity. Additionally, the paper addresses how nanocoatings mitigate issues like electrode degradation, parasitic reactions, and thermal management, ultimately extending battery life and improving safety. By integrating nanotechnology, significant advancements in battery efficiency, longevity, and safety can be achieved, making EVs a more viable and sustainable transportation option. These developments are essential for achieving global carbon reduction goals and supporting a cleaner future.
