Why can't completely replace lead-acid battery electric lithium battery

Electric vehicle is now a lot of people travel choice of transportation, the electric car sales in 30 million vehicles a year in our country, if more people to buy electric cars, electric cars so how should choose? Judge a electric cars is good, is very important for the battery electric vehicle, a lot of netizens curious, online said better than lead-acid batteries, lithium-ion batteries, how to choose now that so much better than lead-acid batteries, lithium-ion batteries why so many electric cars or a lead-acid battery, we solve these doubts are below 1, the lithium battery price expensive lithium-ion battery is not completely replace the lead-acid batteries, the most important reason is that the selling price of lead-acid expensive lithium-ion batteries, lithium batteries because manufacturing is more complex, the cost of two or three times that of lead-acid battery, so the factory price will naturally more expensive, since it is using electric car owners, the majority of people is more willing to accept a lower cost of lead-acid battery; Accepted 2, lead-acid battery from the perspective of the development of electric vehicles in recent years, lead-acid battery has been the mainstream of the electric car battery, the fledgling compared to recent years, lithium-ion batteries of electric cars consumer acceptance and recognition of lead-acid batteries are higher; 3, lead-acid battery technology is more mature though lithium battery research and development has also have decades of history, but compared with lead-acid batteries for more than one hundred years of history, lead-acid battery technology will undoubtedly more mature, in fact, for the moment, the stability of the lead-acid battery is better; Lithium battery is monomer battery high voltage, large specific energy, long storage life ( Up to 10 years) , high and low temperature performance is good, can be in - 40 ~ 150 ℃. Developing power battery and the emergence of new positive electrode materials, especially the development of lithium iron phosphate material of li-ion battery development are of great help. Although it has yet to be fully replace lead-acid batteries, lithium-ion batteries but I believe in the near future, will be the market of lithium-ion batteries.
