Three kinds of hybrid vehicle batteries, lead acid batteries because of serious environmental pollution, has already quit the mainstream of application; nickel-metal hydride batteries, although the mainstream of current business, but the main indicators of laboratory data were lower than the lithium batteries, and the theory basically non-existent room; lithium batteries despite the superior performance, but security can not be guaranteed, and the relatively high costs have also hindered its business. Letter Day Fan Kai Securities analyst Yu says that the poor battery performance so that pure electric vehicles in the mileage has a lot of constraints, in addition to some practical problems - has not yet completed the exclusive use of pure electric vehicle battery charging station.
Although fuel cell vehicles are truly “zero emissions”, but farther away from us. Sheng Wang told reporters that the current fuel cell vehicles using hydrogen energy mainly batteries, not only for the technology is demanding, but also because of hydrogen use, all aspects of a very large investment required.
Days congenial Gu analysts also said that the current high cost of fuel cells - the use of platinum as a catalyst for proton exchange membrane expensive prices of the same, hydrogen Preparation, sealing, storage and transportation difficulties. It is reported that Beijing Olympic Games, manufacturers have provided the cost of fuel cell passenger car to reach 350 yuan / vehicles, and hybrid passenger cars in the same period, compared with the cost of more than 100 million.
