Engineers have taken apart electric vehicle (EV) batteries made by Tesla and BYD, China’s leading manufacturer, and discovered tradeoffs between performance, volume efficiency, and cost.
The study is part of a larger project at the Fraunhofer Research Institution for Battery Cell Production in Germany that aims to bridge the gap between EV battery research and industry. Though companies like Tesla release some information on their batteries’ performance and specifications, little is known about specific materials and production processes. Research scientists need to understand what works on a large scale in order to scale up new innovations, notes Jonas Gorsch, the study’s lead author and the chair of production engineering of e-mobility components at RWTH Aachen Univ. “The first thing we wanted to do was get a benchmark of what is the actual design state-of-the-art,” Gorsch says.
