Beyond Lithium-Ion: The Promise and Pitfalls of BYD’s Blade Batteries for Electric Vehicles

Abstract

Electric vehicles with batteries have started to create a significant impact on the automobile industry nowadays. Along with battery manufacturers, automakers are developing new battery designs for electric vehicles, paying close attention to details like energy storage effectiveness, construction qualities, safety, affordability, and battery performance. The Chinese automaker developed the BYD Blade Battery Build Your Dream (BYD) in 2020. It is primarily a lithium iron phosphate (LFP) battery with prism-shaped cells, with an energy density of 165 Wh/kg and an energy density pack of 140Wh/kg. This essay briefly reviews the BYD Blade Battery’s performance compared to other battery models, model architecture, safety implications of the nail penetration experiment, and cost comparisons with other alternatives.
