Analysis of the difference between lithium batteries and lead-acid batteries

Lead-acid batteries are larger and heavier than lithium-ion batteries. A lithium-ion battery of only 2.5/3 kg, with the same capacity, the lead-acid battery weighs approximately 16/30 kg. Although the lead-acid battery is now beginning to be lightweight, the lithium-ion battery can be flexibly disassembled, etc. The operability is still higher than that of lead-acid batteries. Battery life The current life of lead-acid batteries is about 2 years, and the cycle charge and discharge is generally within 300 times, while the lithium ion battery cycles charge and discharge more than 500 times, and the general life span is more than 3 years. The price of lithium-ion batteries is currently around RMB 450 for mainstream lead-acid batteries, while lithium-ion batteries are relatively expensive. However, with the reduction of lithium-ion battery raw materials, there are also brands calling out the slogan of the lithium battery lead-acid price. Battery cruising range should be the most concerned issue for electric vehicle users. The same applies to 48V batteries. When fully charged, the cruising range of lead-acid/lithium-ion battery electric vehicles is actually similar, depending on factors such as speed and motor size. . Of course, in terms of battery capacity, lead-acid batteries will be slightly larger than lithium-ion batteries. From a comparison point of view, lead-acid batteries and lithium-ion batteries are hard to distinguish. Users who are concerned about price and practicality can choose lead-acid batteries, while those who value battery operability can choose lithium-ion batteries with better performance. However, when using lithium-ion batteries, the safety of the battery is the top priority, so I remind everyone not to be cheap when choosing lithium-ion batteries, and to choose regular, large-brand lithium-ion batteries. This kind of lithium-ion battery will be strictly tested before it goes on sale, and the safety is relatively high.
