From six aspects, the difference between lead-acid batteries and lithium batteries

As an indispensable part of our daily life, batteries are often a topic of discussion. One topic is the advantages and disadvantages of lead-acid batteries and lithium batteries. Today, the difference between the two from the following six aspects of small lithium: 1. Service life: The floating charge life of 12V lead-acid battery is designed to be 5-8 years, but it will be completely scrapped within 1-2 years. For more than 140 years since the invention of lead-acid batteries, there has been a worldwide problem of irreversible vulcanization of lead-acid batteries. It is this reason that the service life of the battery is greatly reduced and the battery is discarded early. Therefore, lead-acid batteries can generally be used for two years. Lithium batteries are durable and consume power slowly. I believe that most consumers have heard that the life of lithium batteries is 500, 500 times the number of times, the battery will die, many friends in order to be able to extend the battery life, the battery is completely exhausted every time it is charged, so there is time for the battery life The impact? The answer is no. The life of a lithium battery is 500 times, not the number of recharges, but a cycle of charging and discharging. The average life span is 4-5 years. 2. Volume and quality: lead-acid batteries generally weigh 16-30 kg and are relatively large; lithium batteries are generally between 2.5-3 kg and relatively small in size, so they are light and easy to carry. 3. Price and warranty period: The mainstream battery currently on the market is 48 volts. If the battery is replaced, the cost of the lead-acid battery is about 450 yuan, and the warranty period is 1 year. Lithium batteries are relatively expensive, about 1,000 yuan, but the warranty period is two years. 4. Battery capacity: At present, the energy density of lead batteries is 40Wh/kg, while the energy density of lithium batteries can reach 200-300wh/kg, which is more than 5 times that of lead batteries. 5. Environmental protection: lead-acid batteries are polluted during processing, improper recycling will cause pollution; lithium batteries are more environmentally friendly. 6. Safety: Lead-acid batteries are safer than lithium batteries. When the temperature of the lithium battery is too high or encounters severe impact, it is prone to fire and explosion. Take the recent Tesla explosion as an example. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
