This electric vehicle uses lithium polymer batteries; don’t forget that these have a shorter life cycle than lithium ion phosphates (unless the technology has improved).
Mind you lighter polymers and more compact cell footprint means more batteries and volts packed under the hood with greater C delivery. Some local electric vehicle builders have been using polymers for a couple of years now, no complaints yet despite their propensity for thermal runaway. From the DOE link below you can see that charge state levels are more acute in these types of batteries and should be taken into account when comparing life cycle statistics. Consistent smooth cation on an autobahnen would be kind to polymers :)
