There are hundreds of thousands of hybrid cars in the United States. In addition, more and more hybrid cars are sold, and these fuel-efficient dealers celebrates record sales. But many environmentalists can lead to problems. They fear that the hybrid eruption of nickel hydride may become a battery-contamination. Environmentalists say that the batteries of hybrid cars, because they do not live for a lifetime, are scattered in the landfills and polluting the soil. But is not it true that conventional gas-fired vehicles have elements and can cause soil contamination without proper disposal?
Many environmental researchers say this is not the problem. There are many hybrid car batteries. Some of these elements are less toxic, while some contain more toxic elements. For example, lead acid and nickel-cadmium batteries are not environmentally friendly, but still have a toxic level and their impact on the environment is low.
Lithium-ion batteries are rapidly growing. Most hybrid vehicles today use lithium-ion batteries as one of the power sources. Toyota was the first company to use the battery in its vehicle. The Toyota Vitz, a compact car that is only available in Japan, uses lithium-ion batteries to illuminate the air conditioner, lights, headlamps and heater while the car is idle.
The ultimate vision of the lithium-ion battery is far from Volvo 3CC. This concept, introduced in 2004, is an electric car, solely for its 3000 lithium-ion cells, which provide all the power. Each cell contains approximately AA batteries. The battery provides 106 horsepower and reduces the car's emissions.
Using batteries, hybrid cars are less robust and slower, but researchers continue to improve car performance and make them faster and safer.
