Arizona State University (ASU) is developing an innovative, formable battery that can be incorporated as a structural element in the vehicle. This battery would replace structural elements such as roof and side panels that previously remained passive, and incapable of storing energy. Unlike today’s batteries that require significant packaging and protection, ASU’s non-volatile chemistry could better withstand collision on its own because the battery would be more widely distributed throughout the vehicle so less electricity would be stored in any single area. Furthermore, ASU’s battery would…
