Ford is making strides to make their Hybrids more efficient and more cost effective eliminating minerals such as: Neodymium, cerium, lanthanum and praseodymium – rare earth metals used in the manufacture of nickel-metal-hydride batteries for hybrid vehicles.
Now lighter, more efficient, more powerful batteries are expected to reduce the company's use of rare earth metals by up to 500,000 pounds a year including dysprosium, the most expensive rare earth metal, which has reduced around 50 percent in the new lithium-ion batteries now powering Ford hybrids.
