Brief introduction of the differences between lead-acid batteries and lithium batteries for electric vehicles

1. Durability/battery life: The service life of lead-acid batteries is generally about 2 years, while lithium batteries are more durable, with a life span of 4-5 years; and lead-acid batteries are generally fully charged and discharged within 300 cycles, while lithium batteries The number of full charge and discharge cycles exceeds 500 times. 2. Volume quality/easy operation: Compared with the light body with a lithium battery of only 2.5/3 kg, the lead-acid battery of the same capacity generally weighs about 16/30 kg; not only the battery is larger in mass, but also bulky; compared to lead-acid The car is laborious toss and turns, and the lithium battery has a detachable design, which is more convenient for riding and transportation. 3. Market price/cost-effectiveness: At present, mainstream lead-acid batteries on the market are about 450 yuan, while lithium batteries are more expensive at about 1,000 yuan; the prices of the two types of batteries are different, and the prices of the corresponding electric vehicles are also quite different. At the same time, the warranty period of lithium batteries is one year longer than that of lead-acid batteries, and can be guaranteed for two years. 4. Cruising range/battery capacity: The same 48V battery. Under full charge, the range of lead-acid/lithium battery electric vehicles is almost the same. The details depend on the speed, motor size and other factors. Of course, in terms of battery capacity, lead-acid batteries will be slightly larger than lithium batteries. 5. Driving kilometers: The same 48V battery, in the case of overflowing electricity, both lead-acid batteries and lithium battery electric vehicles can travel 30-40 kilometers. The speed depends critically on the size of the motor used. 6. Price and warranty period: The mainstream battery on the market is 48V. If it is replaced, the lead-acid battery is about 450 yuan, and the warranty period is 1 year. The price of lithium batteries is relatively expensive, about 1,000 yuan, but the warranty period is two years. . 7. Environmental protection: After the state promulgated the 'Access Conditions for the Storage Battery Industry' in 2012, the lead-acid industry has undergone reorganization and integration, and most manufacturers have adopted internally chemically cadmium-free and arsenic-free green processing, which is more environmentally friendly and energy-saving, only in the recycling process , If the method is improper, it may cause pollution; lithium batteries are relatively greener and more environmentally friendly in terms of processing and recycling. 8. Trend: With the introduction of the new national standard for electric vehicles and bicycles, lightweight batteries and high energy density have become an inevitable trend for power sources. Lithium batteries are undoubtedly the best choice and a development trend. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
