1 | The catalytic converter on your exhaust system contains cerium and lanthanum. | |
2 | Yet another rare earth metal, lanthanum, is a major ingredient for hybrid car batteries. | |
3 | Each electric Prius motor requires 1 kilogram (2.2 lb) of neodymium, and each battery uses 10 to 15 kg (22-33 lb) of lanthanum. | |
4 | To give just one example, every Toyota Prius has over 25 pounds of lanthanum in its nickel-metal hydride battery. | |
5 | In the latest work Bianconi and colleagues used X-rays to study the time-evolution of lanthanum copper oxide. |
