Explain the difference between lead-acid batteries and lithium batteries in detail

How to choose electric vehicle batteries, the difference between lead-acid batteries and lithium batteries There are too many brands and styles of electric vehicles, especially the batteries, whether they are lead-acid or lithium batteries. I don’t know which battery to choose. This problem has become a problem for many customers. The author visited several electric vehicle sales markets on the above issues and found that almost every electric vehicle is equipped with lead-acid batteries and lithium batteries. There are many types of each, which is really dizzying. Subsequently, the author consulted Xupai Battery, a leading brand of high-quality electric vehicle batteries with more than 20 years of experience in electric vehicle battery processing, and one of the world's three largest electric vehicle battery suppliers. According to Xu Pai's analysis, there are now more types of electric vehicles on the market, including motorcycles, bicycles and folding bikes. The battery pack has 36 volts, 48 u200bu200bvolts, 60 volts, etc. Customers must choose according to their situation and personal preferences. The driving interval is short, the road surface is flat, the battery voltage is small, and the body is light; the travel distance is longer, and if you want to take people to climb, you should choose the battery pack with a higher voltage and a more stable body. So what are the differences between lead-acid batteries and lithium batteries? Based on the relevant experience of Solectron’s battery experts, the author summarizes some of the differences between lithium batteries and lead-acid batteries, and hopes to supply them to customers. Please refer to: 1. Durability: Lead-acid batteries generally do not charge and discharge more than 400 times, with memory, and the service life is about 2 years. If you are using a maintenance-free lead-acid battery, you should pay attention to the fact that the battery loses less water, and it is generally not necessary to add distilled water during use. Lithium batteries are durable, consume slowly, charge and discharge more than 500 times, have no memory, and generally have a service life of 4-5 years. According to the analysis by Xupai battery experts, in terms of durability, the battery has good impact resistance. The battery has a complete state of charge and is safe and fixed. It has an amplitude of 4mm, a frequency of 16.7hz, roaring for 1 hour, and no leakage. No swelling or rupture, normal open circuit voltage; 0.1ca battery can be charged for 48 hours, no leakage, no battery swelling or rupture, normal open circuit voltage, and capacity maintenance rate above 95%. High current resistance, fully charged 2CA discharge for 5 minutes or 10CA discharge for 5 seconds, no conductive parts are fused, and the appearance is not deformed. 2. Capacity and quality: Lead-acid battery pack components are generally 16-30kg, with large capacity; lithium batteries are generally between 2.5-3kg and relatively small in size, so they are light and easy to carry. In terms of quality, it is difficult to mean whether it is good or bad. Customers can purchase high-quality brand batteries processed by regular manufacturers according to their needs. 3. Price and warranty period: The mainstream battery on the market is 48 volts. If replaced, the lead-acid battery is about 450 yuan, and the warranty period is 1 year; the price of lithium batteries is more expensive, the demand is about 1,000 yuan, but the warranty period is two years . 4. Kilometer: Using the same 48V battery, both lead-acid batteries and lithium batteries can travel 30-40 kilometers when fully charged. The speed is importantly dependent on the size of the motor used. 5. Battery capacity: lead-acid batteries have a capacity of about 20 amps; lithium batteries have a capacity of 8-10 amps. 6. Environmental protection: In 2012, the state announced the occupational access conditions for batteries. In the future, after the reorganization and integration of the lead-acid occupation, most manufacturers choose to internalize the free green processing of cadmium and arsenic, which is more environmentally friendly and more energy-saving. In the process of recovery, if the measures are not appropriate, pollution may be formed; lithium batteries are more environmentally friendly in terms of processing and recall.
