Did you know that lithium batteries last better than lead acid batteries? Seek to understand the bro

Lithium battery has the characteristics of small size, light weight, long life, and low temperature resistance, and the disadvantage is that it is a bit expensive, but it is cost-effective.

The energy-to-volume ratio of lithium batteries, that is, the energy density, is much higher than that of lead-acid batteries. For the same volume, the energy of lithium batteries is higher than that of lead-acid batteries.

Lithium batteries of the same specification are much better than lead-acid batteries, and their performance is increased by 10-20%.

The volume is only 1 3

But ** is 2-3 times.

Yes 1, service life.

First of all, the service life, lithium battery has high safety, and is still safe and not deformed under harsh conditions such as acupuncture, short circuit, and extrusion. Good performance, can be used at high temperatures, does not affect the service life. So lithium batteries last longer than lead-acid batteries.

2. Endurance. The biggest problem with lead-acid batteries is their high energy density. Conventional lead-acid batteries generally weigh more than 35kg, which will affect the endurance and handling of the machine. Lithium batteries with the same capacity are generally less than 10kg, and the volume is half that of lead-acid batteries.

3.Impact on the environment.

Compared with lead-acid batteries, lithium batteries are cleaner and more environmentally friendly. Everyone knows that lead is a heavy metal, so the production of lead-acid batteries will have a great impact on the environment. However, lithium batteries will not cause environmental pollution in both the production process and the use process.

First, in terms of batteries, lithium batteries are more expensive than lead-acid batteries.

For example, a group of lead-acid batteries on the market is now four or five hundred yuan, and lithium batteries with the same energy generally cost one thousand yuan, and if it is a lithium iron phosphate battery, it is more expensive, so the lithium battery is generally twice or more than the lead-acid battery.

Because the average voltage of lithium batteries is higher than that of lead-acid batteries, that is, the energy density is higher, so that the capacity of lithium batteries is larger for batteries of the same volume.

The same lithium battery, the capacity of ternary lithium battery is larger than that of lithium iron phosphate battery, and lithium iron phosphate battery has a larger capacity than lithium manganese oxide battery.

Third, in terms of the weight of the battery, lithium batteries of the same volume are lighter than lead-acid batteries.

That is to say, the energy density of lithium batteries is greater, for example, the energy of a pound of lithium batteries is equivalent to the energy of three to five kilograms of lead-acid batteries, so under the same energy, lead-acid batteries are heavier.

So if we want to be convenient and lighter to screw, we can choose lithium batteries.

Fourth, in terms of battery safety, lead-acid batteries are safer.

The main ingredient in the lead-acid battery is water, and there is no electrolyte of organic matter, and there are few ** or ** events.

However, due to the fact that lithium batteries have a certain sealing space and contain organic matter, if they are not used properly, there is a possibility of fire.

Fifth, in terms of battery life, lithium batteries are about three times longer than lead-acid batteries.

The criterion for judging this is that under the same quality, the number of cycles of lithium batteries is about 1000 times, and the number of cycles of lead-acid batteries is about 300 times.

Lithium-ion batteries are lightweight and have a high specific energy, but they are safe and cost-effective.

Lithium-ion batteries belong to rechargeable batteries, while lead-acid batteries do.

Alkaline battery: Lithium-ion battery has a cycle life of more than 2,500 times, and lead-acid battery has a cycle life of about 800 times. That is.

It is said that with the same weight, lithium batteries can run farther than lead-acid batteries. Therefore, in terms of energy density, lithium batteries are better than lead-acid.

Battery. From the perspective of service life, a group of good quality lithium batteries can reach about 1,000 cycles, while lead-acid batteries are only about one-third of lithium batteries. Therefore, in terms of service life, lithium batteries are better than lead-acid batteries.

Lead-acid batteries. 1: (Hard!) The lead-acid boss has always been in the spirit of being strong and strong, and the breeze is blowing on the hills. He let him be horizontal, and the bright moon shines on the river as the principle. Lead-acid batteries are easy to feed, let you fall and beat, repair a little, and you can continue to use.

2: (Cheap!) The reason why the lead boss has been able to dominate the battery community for many years and sit in the position of the boss is all because of this reason! Cheap. Except that it's cheap or cheap.

Lead-acid batteries can be used in.

skills, after the use of bad can go to the electric cattle shop to change for a new day.

You can replace it with a new set of batteries by making up the price difference, which minimizes the loss. It's a big benefit for users.

Lithium battery: 1: (light weight, small size) Lithium battery that has been working lightly since childhood.

Compared with lead-acid batteries of the same capacity on the market, the volume of lithium batteries is 2 3 of the volume of lead-acid batteries, and the weight is about 1 3 of the weight of lead-acid batteries. Lithium batteries of the same volume have more capacity than lead-acid batteries.

The high, weight reduction increases the range of the electric vehicle by about 1

0% or so. 2: (Life improvement) Lithium battery has won the way of health, the average life of lithium battery is about one year, about two times higher than the life of lead-acid battery, charging and discharging more than 500 times, the battery has no memory, and has strong shock resistance.

3: (overcharge resistance, good charge and discharge resistance) The lithium battery has opened up the eight veins of the Qi meridian since childhood, so that at normal temperature, the lithium battery can be charged continuously for 48 hours without accidents such as battery expansion, leakage and rupture, and the capacity is maintained at more than 95%. And under the dedicated charger, it can be charged and discharged quickly.

The production cost of lithium batteries is high, and the production equipment is expensive and labor costs account for it.

to about 40% of the production cost, ** about three times that of lead-acid batteries. Its tripling ** brings not a high cost performance. It gives people a flashy feeling, and lithium batteries are not **.

If it is broken, it can only be thrown away, or find a place to bury it, and after thousands of years, future generations will dig it out and it will be an antique.

Because the raw material of lithium is more expensive. The cost is much higher than that of lead-acid batteries.

Lithium batteries are better, because lithium batteries are more environmentally friendly, have better performance, and have a longer mileage, thank you!

Theoretically, it is faster, because with the same voltage and the same capacity, the lithium battery is definitely lighter than the lead-acid battery, and the electric vehicle pays attention to the weight of the vehicle itself.

Of course, lithium batteries also have three shortcomings, their safety and stability are relatively poor, if the operation is improper, it is easy to occur the risk of **. In addition, lithium batteries cannot be discharged with high currents and have high production requirements and higher costs.

Precautions for EV charging

1. Lead-acid battery is different from other secondary batteries, it has no memory effect, so no matter what state of charge the battery is, it can be charged directly without discharging.

2. The battery from the factory to use, generally after 1-2 months, or even longer, the battery during storage due to the self-discharge and other spontaneous reactions inside the battery, consume a part of the power, can not reach the rated capacity value, so before the first use, it is best to supplement the charge.

3. Regarding the charging time of the first charge, because the battery car battery has not been used when it is not used at the factory, it has not experienced charging and discharging, so it is necessary to ensure the normal operation of the battery. Under normal circumstances, the charging time is about 8-10 hours, so that the battery can be fully charged, and then the use can be slightly longer.

Since the weight is reduced a lot, the acceleration must be faster, about 5 kilometers per hour.

The lithium pool for electric vehicles is not faster than the lead-acid battery, but it is longer than the lead-acid battery and is more affected by temperature.

Hello: 1, The battery is the power of the electric car, but it has nothing to do with the driving speed.

2. The driving speed of the electric car is the same as that of the electric vehicleRated speed of the motor] related, related to [Wheel diameter] related, related to [The weight of the vehicle] related, related to [Climbing angle] About ......These factors [All belong to the design speed], which has nothing to do with the battery material.

It is a lithium battery for electric vehicles, which is faster than a lead-acid battery, but the same voltage and the same current speed are the same, but the lithium battery has a longer life than the lead-acid battery, and the lithium battery is lighter and cannot be replaced with each other.

Lithium-ion batteries definitely have a longer lifespan than lead-acid batteries.

This is determined by the construction of the materials used, and the principle is basically similar. Batteries are composed of a positive electrode, a negative electrode, and an electrolyte, but the properties of the materials vary widely. Lead-acid batteries are constructed of lead, lead sulphate and sulphuric acid solution.

With the increase of the number of charge and discharge, the reducing ability of the positive and negative electrode materials becomes worse and worse, and the concentration of sulfuric acid solution will also change.

The life of lead-acid batteries is about two years, and the number of cycle charging and discharging is less than 300 times, while lithium-ion batteries generally have a service life of more than 3 years, and the number of cycle charging and discharging is more than 500 times.

The difference between lead-acid battery and lithium battery

1. Durability.

The service life of lead-acid batteries is generally about 2 years, while lithium batteries are more durable, with a lifespan of 4-5 years; And lead-acid batteries are generally fully charged and discharged within 300 times, while lithium batteries are fully charged and discharged more than 500 times.

2. Volume mass.

Compared with the lightweight body of lithium battery, which is only kilograms, lead-acid batteries of the same capacity generally weigh about 16 to 30 kilograms; Not only the mass of the battery is large, but also the volume; Compared with the laborious tossing and turning of lead-acid vehicles, the detachable design of lithium electric vehicles makes it more convenient to ride and carry.

3. Cost-effective.

The two types of batteries** are different, and the corresponding electric vehicle prices are also quite different. At the same time, the warranty period of lithium batteries is also 1 year longer than lead-acid, which can be guaranteed for 2 years.

4. Cruising range.

The same 48V battery, when fully charged, the range of lead-acid lithium battery electric vehicles is about the same, 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 batteries.

I don't know the size of the battery, and it doesn't make sense to simply live longer. The energy density of lithium batteries is much greater than that of lead-acid, that is, the same weight of batteries, lithium batteries have a larger battery life than lead-acid. Or the same battery life, lithium batteries are lighter than lead-acid.

The biggest advantage of lithium battery is the charging block, which is light in weight, but expensive and poor in safety. The advantages of lead-acid are mature technology, low and safe.

Yes, lithium batteries with the same capacity are about three times the mileage of lead-acid batteries, the number of charge and discharge cycles of ternary lithium batteries is about 800, and the number of charge and discharge cycles of lithium iron phosphate batteries is about 2000. The storage temperature of lithium iron phosphate battery is -10 35, the discharge working temperature of lithium iron phosphate battery is -20 65, and the market reference price of lithium battery is 1250 yuan kwh.

1. The lithium battery is light in weight and small in size. The volume is 2 3 of the volume of a lead-acid battery, and the weight is about 1 3 of the weight of a lead-acid battery. Lithium batteries of the same volume have a higher capacity than lead-acid batteries.

2. The life of lithium battery is long. The average life of lithium batteries is about 4 years, which is about twice higher than the life of lead-acid batteries, with more than 500 times of charging and discharging, no memory of battery use, and strong shock resistance.

3. Overcharge resistance, good charge and discharge resistance.

These two materials are different, lithium batteries are the number of cycles, and the number of charges and discharges is more. Lead-acid batteries are relatively speaking, its performance is fixed, and the weather resistance is relatively good. He can be used in a car where the battery is used outdoors.

It doesn't matter if it's cold or hot. Relatively speaking, lithium batteries are much more expensive, and their power will be greatly affected in too cold or too hot environments, so lithium batteries can only be used in some small electrical equipment at home, and lead-acid batteries are used in some large outdoor equipment.

Why are lithium batteries more durable than lead-acid batteries? Compared with lead-acid batteries, lithium batteries have obvious advantages over their long service life. The service life of a lead-acid battery is about 2 to 3 years, and the number of charges can be about 300 times.

The service life of lithium batteries is 4 to 5 times that of lead-acid batteries, and most lithium batteries have a shelf life of up to 10 years, and the number of charges can reach more than 500 times.

This is determined by the difference in internal materials.
