The steady increase in sales of electric vehicles (EVs) has led to advances in EV batteries, particularly those using lithium ion (Li-ion) technology. While
early hybrid vehicles featured nickel-metal hydride (NiMH) batteries, Li-ion batteries have taken over, particularly in the latest generation of plug-in electric vehicles (PEVs).
“The shift to lithium ion represents a major endorsement of the ability of this chemistry to perform consistently in an automotive environment,” explained David Alexander, senior research analyst with Navigant Research. “Most of the major automakers have introduced battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) models in the last two years, almost all of which use lithium ion batteries for onboard energy storage.”
Demand for Li-ion batteries will be driven primarily by BEVs throughout the forecast period thanks to the size of the battery required, according to the IHS report entitled 'Electric Vehicle Batteries'. Both hybrid EVs and PHEVs will decline slightly as a percentage of the total, while stop-start vehicles (SSVs) will see their share of the Li-ion battery market steadily increase, as a result of higher volumes of vehicle sales and the adoption of Li-ion batteries in stop-start models as the cost-per-kilowatt-hour decreases.
