IDTechEx: NiMH batteries still dominant in full hybrids, largely due to Toyota

Green Car Congress

While the lithium-ion battery is dominant in battery-electric vehicles, NiMH batteries are still the most common in full hybrid vehicles (HEVs), according to a new report—“ Full Hybrid Electric Vehicle Markets 2021-2041 ”—from IDTechEx. It is also much more technologically mature and lower cost than Li-ion.
