The field of energy research faces two main challenges: promoting the use of sustainable energy and developing suitable power sources for electrical propulsion. For extensive use of sustainable energy we need appropriate storage technologies. Rechargeable Li ion, magnesium and lead acid (LA) batteries can be developed as storage technologies for load leveling applications. Super-capacitors (EDLC) can be also suitable for this application. The presentation will discuss selection of suitable electrodes materials, for instance, combining Li-Ti-O compounds (negative electrodes) and some olivine compounds (positive electrodes) in Li batteries or using novel carbonaceous materials in LA batteries. We will examine how Li battery technology can provide high energy density for EV applications, beyond the state of the art. We will discuss options for electrochemical driving range extenders. Challenges and limitations in R&D of Li-S and Li-oxygen batteries will be addressed.
