The advent of hybrid electric vehicles in the past decade gave way to mass production of nickel-metal hydride (Ni-MH) batteries in automobiles, which have twice the energy density of lead-acid batteries. Now the demand for long range electric and plug-in hybrid electric vehicles in the coming decade is giving way to mass production of lithium-ion batteries in automobiles with twice the energy density of Ni-MH batteries. The lithium ion battery offers 100-150 Watt hours per kilogram, Nickel Metal Hydride (Ni-MH) offers 65-70 Wh/kg, and lead-acid offers 30-40 Wh/kg.

NY Times reports that almost half of the world’s lithium, the mineral needed to power plug-in hybrid or electric vehicles, is found in Bolivia. The United States Geological Survey says 5.4 million tons of lithium could potentially be extracted in Bolivia, compared with 3 million in Chile, 1.1 million in China and just 410,000 in the United States.

The majority of plug-in hybrid and electric vehicles on the market use lithium-ion batteries including:

  • Chevrolet Volt, to be launched in 2010 or 2011 and priced under $40,000, will uses a lithium-ion battery with an all-electric range of 40 miles produced by a full plug-in charge.
  • BYD Auto’s F3DM PHEV-68, which began selling in 2008 in China, uses a lithium iron phosphate battery with an all-electric range of 68 miles.
  • Ford Motor recently signed a contract with Johnson Controls-Saft to provide lithium-ion batteries for Ford plug-in hybrid vehicles. Ford announced today that it will introduce a battery-only commercial van in 2010, followed by a passenger car built on the same technology in 2011, and a plug-in vehicle by 2012.
  • Toyota plans to demonstrate 150 Prius plug-in hybrids this year with several lithium-ion battery packs that will be teamed with a 1.8-liter four-cylinder engine. U.S. sales of the Toyota plug-in hybrid are expected to begin sometime after 2010.
  • As of last year a major battery manufacturer, A123 Systems, was accepting purchase orders for conversion kits (hybrid to plug-in hybrid) to retrofit existing nickel metal hydride powered Toyota Prius hybrids with a lithium-ion power train with all-electric range of 30 miles per fully charged battery set.
