Li-ion Battery Research Improving Safety


Lithi­um-ion bat­ter­ies con­tain 6-times more ener­gy than lead-acid bat­ter­ies and 2–3 times more than nick­el-met­al hydride bat­ter­ies, mak­ing them excel­lent can­di­dates for the low-weight needs of plug-in hybrid and all elec­tric vehi­cles. Safe­ty con­cerns cen­ter around elec­trolytes and gas­es in li-ion bat­ter­ies that are flam­ma­ble when released but research is steadi­ly improv­ing safe­ty.
