Toyota Sticking With NiMH for Strong Hybrids in Near Term

Green Car Congress

Although Toyota has been working on Li-ion batteries for strong hybrids, and has had 126 Priuses equipped with Li-ion packs on the road for the past three years, NiMH cost performance wins compared to lithium for this application, Kuroda said. Toyota has been able to bring down the cost of the NiMH pack in the Prius “dramatically”, he said.

Anderman report sees strongest growth for full-hybrid systems; Li-ion batteries for hybrids may be in short supply

Green Car Congress

Although NiMH is still the dominant battery in the high-voltage hybrid market, Li-ion technology started to take market share around 2009 and is expected to continually increase its share with time. The 170-page report also finds that while the combined global EV and plug-in Hybrid (PHEV) market share is expected to grow to about 1.5%
