The heavy weight of EV batteries is one of the factors that pull down driving range, no matter what other bells and whistles the R&D people come up with. Scientists calculate that simply removing the battery would increase range by 70%, except for one tiny detail, which is the absence of a battery. Or not, as the case may be. The scientists behind that 70% estimate have been hard at work developing a massless EV battery, meaning a battery that adds no extra weight because it pulls double duty as a working part of the vehicle’s structure. Massless EV Batteries Are Coming, Eventually
The research team, based at Chalmers University in Sweden, has been developing massless EV batteries since at least 2007. The key ingredient is carbon fiber, the same lightweight but tough versatile material that goes into auto body parts. READ FULL ARTICLE
