Contrast the cost prices of lead acid battery and lithium battery

Source: 2020 - 04 - 02 but hits: the lithium battery manufacturers to compare the cost of lead-acid battery and lithium battery, lithium battery manufacturers to compare the cost prices of lead acid battery and lithium battery. Since 2017, the state has carried out the comprehensive environmental action, recovery of lead smelters to shut down, their production, lead-acid battery lead to the market price rise all the way, dealers profit more and more thin. Now, the original data, lithium-ion batteries, on the other hand, such as manganese acid lithium, lithium carbonate, etc. , with the acceleration of capacity expansion, the market price decline year by year, the gradual loss of lead-acid battery price advantage, lithium battery will replace lead-acid batteries have great development. In this paper, the lead-acid battery and lithium battery costs are compared. Lead-acid battery 1 catty price is about $4820 to $558. Lithium battery to the market price of about 950 yuan. Conclusion: under the same voltage, the ternary lithium battery is the price of the lead-acid battery 1. About seven times. The standard for the use of funds generally lead-acid battery life 60% of the charge and discharge cycle capacity of about 300 times. According to the professional standard lithium-ion batteries more than 500 times charging and discharging cycle 80% capacity, more than 800 times 60% capacity. Measurement standard: same as the 60% attenuation limit standard. Lead-acid battery single cycle operation cost: 558 yuan / 300 = 1. 86 yuan; Lithium battery single cycle running cost: 950 yuan / 800 = 1. Conclusion: 19 yuan lead-acid batteries cost about 1 of ternary lithium batteries. 57 times. Lead-acid battery recycling depreciation, of course, the price is higher, the market price about 40% of the new battery; Lithium battery depreciation is worthless, the market price is about 5% of the new battery. Technology is the key. From the point of technical complexity, lithium-ion batteries, there are still many bottlenecks need breakthrough, but from the point of view of water and dust, lead-acid battery as powerful lithium-ion batteries. After all, pure electric vehicle battery power is generally on the car chassis, daily travel turbulence is inevitable, short-term water travel, at this point, may reach IP67 significantly more safety of lithium ion battery. Then the volume. For lead-acid battery cell density is low, in the same battery capacity, the volume of a lithium ion is much smaller than lead-acid batteries, and light, general is two-thirds the size of lead-acid batteries, lithium battery volume weight, about a third of the lead-acid battery weight and weight loss range can make the batteries of electric cars have been increased by about 10%. And then there is life. Although recycling categories, lead-acid battery is more complex, more convenient, but life, than deep deep discharge only need 400 times, only 2 years of lead-acid battery, circulation flow more than 3000 times, SOC can still more than 70%, in 3 - basically 8 years of lithium ion battery is more suitable. In short, if you buy an electric bike a year can only switch, and then select the lead-acid battery electric vehicle is a cost-effective, assuming you don't consider changing, then starting from the second year in a replacement battery, lead acid battery low capital advantage become negligible, such as the third year to replace the battery again, the capital of lead-acid batteries far more than lithium batteries.
