 Lithium battery is better. Lithium batteries are more than 3 times higher than lead-acid batteries, either volume ratio energy, or weight ratio energy. Lithium battery is smaller, weight is lighter.

Long cycle life. It's far from running, the key is to watch the battery capacity, and the light is alone, no meaning. For example, it is 48V20AH, lithium electricity and lead acid are basically the same, because the capacity is the same, but lithium electricity will be light, so it is a bit more than lead acid.

But if lithium is 48V10AH, lead acid is 48V20AH, then it is certain lead-acid, no need to say. Simple point to say, who is much bigger, who is far away, lithium battery is better than lead acid, can be discharged, can be powered, others. Lithium battery electric vehicle: Advantages: high efficiency.

The body is light, the mileage is far, the user use and maintenance requirements are not strict. Disadvantages: high price, domestic lithium battery technology is uneven, lithium battery for electric vehicles has safety hazards. Lead-acid battery electric vehicle: Advantages: high cost performance.

Battery prices are relatively cheap, large capacity, battery can choose to brand, technology maturation. Disadvantages: the efficiency is not high. The battery is invisible, causing the body in the body, short mileage, battery needs to be maintained on schedule.

Hello, choose which battery to see your models and your needs. At present, the variety of lead-acid batteries can cope with various requirements, but it is not convenient for the time, the price is equivalent to lithium battery. Lithium battery is not very mature due to soon, it is not very mature, but its life and light will dominate, and the price is also expensive.

Lithium battery You can search for security after large capacity? Cost feasibility? Why is the mobile phone battery exploded lead-acid batteries although bulky but stability is much better than lithium batteries! Cost basics are all accepted! Stability and safety and cost are higher than lithium battery! As long as it is a battery, the lead-acid battery is also a heavy contamination! The lead-acid battery is "really cheap" or "false affordable"? We must make a comparison accordingly, there is a comprehensive understanding of all aspects, the same, buy electric vehicles, such as: future maintenance, charge and discharge electric losses, replace the battery, etc., will spend a lot of money in the future! It is understood that the general consumer's electric vehicle replacement cycle is around 4-5 years. Although the lead-acid battery is cheap, the annual loss is high, often takes a year.

In general, a better lead-acid battery price is about 600 yuan, so on the same electric vehicle, it will take about 2400 yuan on the battery. Let's take a look at the electric vehicle that configures lithium battery. Buy a lithium battery electric car approximately 3,500 yuan.

Lithium battery warranty for 3 years, that is, in the past three years, we don't have to spend money to replace the battery. And the life of the lithium battery is very long, basically in 5 years. In other words, it is actually as long as we usually love it, it will not have other spending on the electric vehicle in five years.

Currently sell electric vehicles, whether it is battery brand, style or brands, and lead-acid batteries and lithium batteries dominate the lead, the following small series makes you clearer the relationship and difference between these two. Normally, the weight of the lead-acid battery pack is 16-30 kg, the volume is large; the weight of the lithium battery is generally 2.5-3.

0 kg, the volume is relatively small, so the riding is light and convenient. From the quality, the quality of the two is difficult to define, but consumers can purchase the quality battery produced by the formal manufacturer according to their actual needs. The main material of the lithium battery, the negative material, the collector, the separator, the electrolyte, etc.

are much higher than the lead-acid battery. The assembly equivalent and external circuit system of the lead-acid battery is extremely low. Due to the cause of the production process, the labor cost of the lithium battery is relatively large.

In manufacturing cost, the labor cost of lithium batteries accounts for more than 40%, while the labor cost of the lead-acid battery is generally 10% to 20%. The mechanical equipment used in lithium batteries is expensive, high value, and the depreciation of mechanical equipment is large. Most of the process in production is irreversible, and lead-acid batteries are reversible and re-use.

The recovery value of the lead-acid battery after use is over 40%, and the value of the lithium battery is almost zero. Lithium batteries are more than 3 times higher than lead-acid batteries, either volume ratio energy, or weight ratio energy. Lithium battery is smaller, weight is lighter.

Long cycle life. Lithium battery is usually more than 800 times, and the lithium battery using lithium iron phosphate positive electrode material can reach 2,000 times, which exceeds 1.5 to 5 times lead acid batteries.

This greatly reduces the cost of use of lithium batteries, prolonging service life, and improves the convenience of use. Wider range of charging efficacy. This is the unique advantage of lithium batteries.

When needed, the charging time can be controlled at 20 min to 1 h, and the charging efficiency is more than 84%. This feature will get better on the basis of further technological innovation. We know, general comparison of energy storage products should be performed from the weight of energy density, volume energy density, service life, price, applicability, national policies: weight energy density current lithium battery energy density is generally 200 ~ 260Wh / g, Lead acid is typically from 50 to 70WH / g, then the weight density lithium battery is 3 to 5 times lead acid, which means that the lead-acid battery is 3 to 5 times the lithium battery, so Can be lightweight, lithium batteries account for an absolute advantage.

The volumetric capacity density of the volumetric energy density lithium battery is usually about 1.5 times the lead-acid battery, so in the case of the same capacity, the lithium battery is 30% lower than the lead-acid battery volume. The use cycle is currently more popular with three yuan and iron, and the number of three-dimensional dynamic lithium battery cycle is usually more than 1000 times.

The number of cycles of lithium iron phosphate cells is more than 2000 times, and the number of cycles of lead-acid batteries is usually only 300. ~ 350 times, so the life of the lithium battery is about 3-6 times the lead-acid battery. Price Currently, the lithium battery is more lead-acid than lead, about 3 times, but combined with life analysis, investing the same cost, is still a longer lithium battery usage cycle.
