What are the differences between lead-acid batteries and lithium batteries for electric vehicles?

Seven 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 lifespan of 4-5 years; and the cycle of lead-acid batteries The complete charge and discharge cycle is generally within 300 times, while the number of complete charge and discharge cycles for lithium batteries exceeds 500 times. 2. Volume quality/easy operation: Compared with the lightweight body with a lithium battery of only 2.5/3 kg, the lead-acid battery with the same capacity generally weighs about 16/30 kg; not only the battery is larger in mass, but also larger in size; compared to the lead-acid car The laborious toss and turns, the detachable design of the lithium battery makes it more convenient to ride and transport. 3. Market price/cost-effectiveness: The current mainstream lead-acid batteries on the market are about 450 yuan, while the price of lithium batteries is 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, depending 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, when fully charged, both lead-acid batteries and lithium battery electric vehicles can travel 30-40 kilometers. The speed depends on the size of the motor used. 6. Price and warranty period: The mainstream battery on the market is 48V. If 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. Most manufacturers have adopted internally chemically processed 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.
