Abstract: With aggravated problems such as global warming and deteriorated ecological environment, global electric vehicle industry has developed rapidly in recent years. Subsequently, "oil consumption peak theory" and "petroleum age termination theory" cause a temporary clamor. The nature of developing electric vehicles is an energy transformation from direct use of fossil energy to use of clean energy. But, the development of electric vehicles, besides its own technology, especially for battery’s distance per charge, charging rate and battery recycling, being difficult to realize great breakthrough in a short time at present, is crucially restrained by resources(clean energy resources and battery material resources such as lithium and cobalt), thus resources condition determines the development speed of electric vehicles. Even if electric vehicles will be popularized on a large scale in future, only the substitution of gasoline cars can be realized, but heavy machinery, trucks, ships and airplanes are still difficult to be electrified. In the mid-long term, electric motors and internal combustion motors will both exist, and every kinds of energy will co-exist and develop in a long term, so large-scale development of electric vehicles is still an arduous task and the road is long.
