Lead-acid battery and lithium battery competition

Boosted by the Tesla effect, lithium batteries are favored by the market, and it is considered inevitable that they will replace lead-acid batteries. However, people in the industry are divided.

Li Ke, chief analyst of real lithium research, said that the current battery industry as a whole is not good, insist on doing lead-acid batteries "difficult to have a way out," and insisted on doing lithium-ion batteries, then pass winter may be ushered in the spring. He said: "The current plight of the lithium battery industry is only temporary, and it should improve after two or three years."

Liu Yanlong, secretary-general of the China Chemical and Physical Power Industry Association, said that if domestic companies could not make breakthroughs in the lithium battery technology and quality, the domestic market would be occupied by foreign products. “Is it not possible to promote lithium batteries quickly or because of price problems?”

It is reported that in the cost of pure electric vehicles, the battery accounts for 40%-60%, the average automobile is the service life of 15 years, and the service life of lithium batteries in pure electric vehicles is only 5 years. The price of an ordinary family car is about 100,000 yuan. If you buy a pure electric car with the same configuration, you need to pay another 100,000 yuan for the battery cost. In the field of electric bicycles, the average replacement cost of lead-acid batteries is about 450 yuan, and that of lithium batteries is about 1,000 yuan.

However, Cao Guoqing, deputy secretary-general of the China Battery Industry Association, believes that the use of lead-acid batteries will be reduced in the later period, but it will remain a monopoly for a long period of time. "Lithium batteries can replace lead-acid batteries in local markets, but It cannot be completely replaced."

According to public information, in the field of electric bicycles, lithium battery electric vehicles accounted for relatively small. In 2012, the country’s production of electric bicycles reached 35 million, and lithium-ion battery electric bicycles reached 1.5 million, accounting for 5% of electric bicycles.
