Li-ion battery car will exceed Ni-MH battery vehicles in several years
According to Yano Economic Research Institute predicted that hybrid electric vehicle market will continue to expand, while lithium batteries will also benefit from in 2011 began to replace nickel-metal hydride VGP-BPS2 batteries, lithium-ion is expected in 2015 rechargeable batteries in the automotive market, the proportion will rise to 15%, the market ¥ 100,000,000,000 size of a breakthrough, but by 2020 this proportion will be further raised to 30-40%, the market scale reached 2000-2600 yen.
And according to Japanese IIT predicts that the use of liquid lithium-ion battery (LiB) of the hybrid electric vehicle (HEV), plug-in hybrid electric vehicle (PHEV), a pure electric vehicle (EV) from 2009, 2010 began the introduction of relatively large number, 2012, its market has not yet reached the size of nickel-hydrogen cell vehicles, but in 2013, began to go far beyond its size Ni-MH battery car; and, from 2013 onwards, Ni-MH VGP-BPS8 battery car size of the market had been the basic fixed , almost no growth, but the lithium battery market size cars, along with the new car market in the growth of the energy gradually grow and become the market mainstream.
Prior to the relatively nickel-hydrogen cell vehicles, lithium battery vehicle safety and cost issues more prominent. At present, these problems have to get better from the technical aspects of the solution.
Such as cost, according to Golden State securities analysis, lithium batteries cost more than nickel-metal hydride batteries, lithium batteries is mainly due to previously mainly used as cathode material of lithium cobalt oxide, which are noble metals cobalt, the price is high (50 yuan / ton, the amount of 60% cobalt lithium cobalt price of more than 400,000 yuan / ton); Now lithium battery cathode materials have been gradually cheaper lithium manganese oxide and lithium iron phosphate (18-30 yuan / ton range) transition.
Although the 2010 lithium batteries cost more than nickel-metal hydride batteries, but the cost of lithium batteries is expected to begin in 2010 will be dropped from the nickel-metal hydride batteries with a considerable level, even after the cost of lithium batteries will be significantly lower than the nickel-metal hydride batteries.
