Buy electric cars, lithium battery or lead acid battery?

Source: 2020 - 04 - 01 'hits: time to buy electric cars buy lithium battery or lead acid battery? Lead-acid batteries, lead-acid battery manufacturing cost is low, the price is relatively cheap, and in the maintenance, lead-acid battery maintenance more convenient, maintenance slightly, and sustainable use. Lead-acid batteries can also use back, after use the old can go to replace electric shop, pay the difference in a set of new batteries, minimum loss, for users to benefit a lot. Here also introduced a kind of green energy high energy battery, it can use the original battery internal space, add the positive and negative on the number of data and the electrolyte, battery capacity increased by 10%, and range increased by 10% or more; Batteries have improved, cycle life has been extended. Despite the above advantages, lead-acid battery also has its disadvantages: large volume, battery capacity is limited, life is short, usually in the lead-acid battery of 400 deep cycles within, in 2 - life 3 years or so, the presence of the heavy metals tend to form with the environmental pollution. Compared with lead-acid batteries, lithium-ion batteries two-thirds of the volume of the lithium battery is lead-acid batteries, part is 1/3 of lead-acid batteries. With the size of the lithium ion battery than lead-acid battery capacity is larger and therefore more convenient to carry, and most of the lithium ion battery can be extracted and charging. Lithium battery life expectancy of about 4 years, lead-acid battery is 1. About five times. Charge and discharge more than 500 times, some even more than 1500 times. Battery no memory, impact resistant ability is stronger. Compared with lead-acid batteries, lithium batteries on the environment pollution is small, do not contain any heavy metals and rare metals, non-toxic, whether in the production and use of no pollution, accord with the eu RoHS rules, can avoid the environmental pollution caused by the common battery replacement, greener. Presented here is to use green source of lithium iron phosphate batteries, has a 2000 - cycle, long service life; Heat loss point reached 270 degrees, which makes it more secure. Using battery SOC score method, power accuracy reached 1%. Continuous constant power output, do not affect electricity. Although there are a lot of advantages of lithium batteries, but its defect is clear, lithium battery manufacturing cost is high, the production equipment expensive labor costs account for about 40% of the cost of production, the price is about three times that of lead-acid batteries, lithium battery is basically no recycle value, cannot be recycled; Lithium is more sensitive to temperature, winter below lead-acid batteries battery life. In lead-acid batteries is introduced and the advantages and disadvantages of lithium batteries, lithium battery or lead acid battery good? About the present, can only be determined by the friend's needs and, if you choose to cost-effective, you can choose the lead-acid battery. For battery can extract and charge as well as the requirement of a longer battery life, advocate choose lithium battery.
