To give just one example, every Toyota Prius has over 25 pounds of lanthanum in its nickel-metal hydride battery.

Toyota is therefore likely to stick with the heavy and range-limited nickel-metal hydride battery for the third-generation Prius, due in 2009.

For the nickel-metal hydride version of the battery, that material is a substance called nickel oxyhydroxide.

The c's program managers were thus obliged to dial back to the previous generation's 1.5-liter engine (the Gen III Prius uses a 1.8-liter), a smaller traction motor (60 hp vs. 80 hp) and a lighter, cheaper nickel-metal hydride battery (19.3 kilowatts vs. 27 kW).

Toyota's top hybrid engineers say they are all for plug-ins, but they don't think the lithium-ion batteries they depend on will be ready to meet their stringent quality standards for several years. (They cannot resist a polite titter about spontaneously combusting laptop batteries.) Toyota is therefore likely to stick with the heavy and range-limited nickel-metal hydride battery for the third-generation Prius, due in 2009.

Its original nickel-metal-hydride battery packs have been replaced with lead acid batteries to extend the distance the car can travel on electricity.
