Lithium battery manufacturers compare the cost of lead-acid batteries and lithium batteries. Lithium battery manufacturers compare the cost and price of lead-acid batteries and lithium batteries. Since 2017, the country has carried out comprehensive environmental protection actions, and the production of recycled lead smelters has been suspended and restricted, which has caused the price of lead-acid batteries on the market to rise all the way, and the profits of distributors are getting thinner. On the contrary, now, the original data of lithium batteries, such as lithium manganate, lithium carbonate, etc., with the accelerated expansion of production, the market price is decreasing year by year, and the price advantage of lead-acid batteries is gradually lost. Lithium batteries will replace lead-acid batteries and usher in great development of. This article compares the cost of lead-acid batteries and lithium batteries. The price of 4820 lead-acid batteries per kilogram is about 558 yuan. The market price of lithium batteries is about 950 yuan. Conclusion: Under the same voltage, the price of a ternary lithium battery is about 1.7 times that of a lead-acid battery. The capital used is generally about 300 times the charge-discharge cycle capacity of 60% of the lead-acid battery life standard. According to the professional standard of lithium battery, the capacity is 80% for 500 cycles of charge and discharge, and 60% for 800 cycles. Measurement standard: the same as the 60% attenuation lower limit standard. Single-cycle operating cost of lead-acid battery: 558 yuan/300 timesu003d1.86 yuan; single-cycle operating cost of lithium battery: 950 yuan/800 timesu003d1.19 yuan Conclusion: The cost of lead-acid batteries is about 1.57 times that of ternary lithium batteries. Of course, the depreciation and recycling price of lead-acid batteries is relatively high, the market price is about 40% of new batteries; the depreciation of lithium batteries is worthless, the market price is about 5% of new batteries. Technology is the key. From the perspective of technical complexity, lithium batteries still have many bottlenecks to be broken through, but from the perspective of water and dust, lead-acid batteries are not as powerful as lithium batteries. After all, the battery power of pure electric vehicles is generally placed on the chassis of the car. Daily travel will inevitably have bumps, and short-term water travel. At this point, lithium batteries that can reach IP67 are significantly safer. Then there is volume. Because the battery density of lead-acid batteries is very low, at the same battery capacity, the volume of lithium ion is much smaller and lighter than that of lead-acid batteries.Generally, the volume of lithium batteries is 2/3 of the volume of lead-acid batteries, and the weight is about three minutes. One of the weight of lead-acid batteries, and weight loss can increase the battery range of electric vehicles by about 10%. Then there is life. Although the recycling category, lead-acid batteries are more complicated and convenient, but the life span is only 400 times compared with deep charge and deep discharge, and only 2 years of lead-acid batteries. The cycle flow exceeds 3000 times, and the SOC can still exceed 70%, which is basically 3- An 8-year lithium battery is more suitable. All in all, if you buy an electric bicycle for one year, you can only switch on and off, and then choose a lead-acid battery electric vehicle is a cost-effective, assuming you do not consider changes, then start to replace the battery from the second year, the lead-acid battery has low capital advantages It becomes negligible, if the battery is replaced again in the third year, the capital of lead-acid batteries far exceeds that of lithium batteries.
