Lithium-ion battery and lead-acid battery staged 'Song of Ice and Fire'
After the new national standard imposes a number of hard and fast regulations on electric bicycles, many people said that the fate of the 'indigenous' lead-acid batteries for electric bicycles is about to come to an end. In recent years, as a century-old 'old manSo what are the differences between lithium-ion batteries and lead-acid batteries? In terms of weight. In the case of the same capacity, lead-acid batteries are 3 to 5 times the weight of lithium-ion batteries, so the volume of lead-acid batteries is also larger, and the new national standard stipulates that the weight of electric bicycles does not exceed 55kg, which will make it lighter. Lithium-ion batteries are better than heavyweight lead-acid batteries. Environmental protection. Lead is a heavy metal, and both the process of producing lead and the waste after use will cause pollution, which is contrary to the green harmony advocated by the country. In comparison, lithium-ion batteries have very little pollution, which is also an important reason why they are promoted and actively used in my country, especially in large cities. In terms of life. Lithium-ion batteries have a long cycle life. Among them, the lithium iron phosphate battery can reach 2000 times, that is, it can be fully charged and discharged 2000 times, and it has no memory effect and can be charged and discharged. The cycle life of lead-acid batteries is at most only 1/4 of that of lithium iron phosphate batteries, which also means that lead-acid batteries are scrapped in less than 2 years, while lithium iron phosphate batteries can be used for more than 5 years. In terms of price. The price of lithium-ion batteries is indeed more expensive than that of lead-acid batteries, but if it is evenly spread over the service life, lithium-ion batteries are still more cost-effective. As far as the country is concerned, due to price factors, lead-acid batteries in the field of electric bicycles are still the protagonist, but lithium-ion batteries are appearing in an unstoppable manner. The 34th batch of electric bicycle catalogues published by Beijing showed that the shortlisted electric bicycle battery types are all lithium batteries. China Tower has also announced that it will stop buying lead-acid batteries and fully use power lithium batteries. It is foreseeable that under the guidance of national policies and the example of important cities and departments, the market share of lithium batteries will gradually increase. Of course, the state does not compulsorily require people to purchase lithium battery electric vehicles, and people still have the right to freely choose lithium battery products or lead-acid battery products. Many people and electric bicycle sellers are still on the sidelines, and the 'war' between lithium-ion batteries and lead-acid batteries may take some time.
