Lithium ion batteries (LIBs) became the most important rechargeable electrochemical energy-storage system for portable consumer electronics devices and are presently advancing to a key technology for enabling the broad commercial launch of electric vehicles (EV). For a broad acceptance of this technology and a market breakthrough of EVs several issues have to be addressed to overcome customers' objections against this technology. The cruising range and hence the energy density (Wh/L) and specific energy (Wh/kg), respectively, is a most crucial parameter. Different cell chemistries are discussed as alternative for LIB to increase the energy density, but the advantages and disadvantages (e.g. energy density, lifetime and safety) of these so-called Post-LIB systems and other alternatives with respect to LIBs and advanced LIBs have to be compared carefully.
In this presentation, we will highlight the most recent findings in view of practically realizable specific energies and energy densities of various battery chemistriesas well as the safety and aging characteristics of LIBs and will compare it with state of the art technologies.
