Energy Density Levels for Various Rechargeable Batteries

5 Energy Density Levels for Various Rechargeable Batteries 

For the benefit of readers and owners of EVs and HEVs, this section summarizes the important parameters of rechargeable batteries, which are best suited for EVs and HEVs. Critical performance parameters of these three distinct rechargeable batteries are shown in Table 4.5.

The Li-ion battery is sometimes identified as Li-ion-manganese oxide (Li-ion-MnO). Essentially, the battery is made out of hthium and manganese oxide, whereas the Li-ion-polymer batteries are fabricated using lithium and polymer materials. Both the Li-ion-MnO and Li-ion-polymer battery packs are widely used by the EV and HEV manufacturers. The Li-ion-polymer battery packs can be easily damaged if not handled with extreme care. This particular battery pack requires outside walls made from high—mechanical strength material to protect the delicate control of IC circuits and battery structure [5]. The Li-ion battery packs have unique characteristics.
