After the new national standard has imposed，a number of rigid regulations on electric bicycles, many people said that the fate of the "indigenous people" lead acid batteries for electric bicycles is about to come to an end. In recent years, lead-acid batteries, as an "old man" with a history of 100 years, have been constantly suppressed by the "new rookie" lithium ion battery in the battery industry. The two have staged "a song of ice and fire." So what are the differences between lithium-ion batteries and lead-acid batteries?
In terms of weight， in the case of the same capacity, the lead-acid battery is 3 to 5 times the weight of the lithium-ion battery, so the volume of the lead-acid battery is also larger, and the new national standard for the quality of the electric bicycle does not exceed 55kg, which will make it lighter. Lithium-ion batteries are superior to heavy-duty lead-acid batteries.
Environmental protection，Lead is a heavy metal, and the process of producing lead and the waste after use can cause pollution, which is contrary to the green harmony advocated by the state. Compared with lithium-ion batteries, there is little pollution, which is also an important reason for its promotion and active application in China, especially in large cities.
Life expectancy，the lithium-ion battery has a long cycle life, in which the lithium iron phosphate battery can reach 2000 times, that is, it can be fully charged and discharged 2000 times, and has no memory effect, and is charged with the charge. Lead-acid batteries have a cycle life of at most 1/4 of that of lithium iron phosphate batteries, which means that lead-acid batteries are less than 2 years old, and lithium iron phosphate batteries can be used for more than 5 years.
Price, lithium-ion batteries are indeed more expensive than lead-acid batteries, but lithium-ion batteries are more cost-effective if they are spread over their useful life.
As far as the country is concerned, lead-acid batteries in the field of electric bicycles are still the protagonists due to price factors, but lithium-ion batteries are debuting in an unstoppable situation. The 34th batch of electric bicycle catalogues announced by Beijing showed that the types of electric bicycles that were short-listed were all lithium batteries. China Tower has also announced the suspension of lead-acid batteries and the full use of power lithium batteries. It can be foreseen that under the guidance of national policies and the performance of important cities and departments, the market share of lithium batteries will gradually increase.
