Which one is better, storage battery or lithium-ion battery?

The lithium-ion battery is better. No matter volumetric specific energy or gravimetric specific energy, lithium-ion battery is three times better than lead-acid battery. Lithium-ion battery has smaller volume, lighter weight and longer cycle life.

Running is it far, the key see battery capacity. It doesn't make sense to say which one is better.

Are 48 v20ah, for example, li-ion battery and lead acid basically the same, because the capacity is same, but the lithium electricity will tap, so a little further than lead acid.

But if the lithium electricity is 48 v10ah, lead-acid is 48 V 20Ah, it must lead acid, needless to say. Who said simple point is that large capacity which runs far, lithium electricity advantage is lighter than the lead-acid, large current discharge, other are all the same.

Lithium battery electric vehicles:

Advantages: high efficiency. Light body, range far, not strict with users to use and maintenance.

Weakness: the price is high, the domestic lithium electricity technology is uneven. Lithium electricity for electric vehicles are unsafe.

Lead-acid battery electric vehicles:

Advantages: high cost performance. Battery prices are relatively cheap, large capacity, battery can choose brand, more mature technology.

Weakness: the efficiency is not high. Since the big battery pack is heavy, which leads to the body, mileage is shorter, cells need timely maintenance.

Hello, choose what kind of battery to see your models and your needs. The lead-acid battery variety can cope with all kinds of requirements, but heavier sometimes inconvenient, price is equal to the lithium electricity cheap is not good. Shortly with lithium electricity, various aspects are not very mature, but its life and light has a great advantage, the price is expensive.

You can search for lithium-ion batteries in series with the large capacity after security? What about the cost of feasibility? Why mobile phone battery explosion lead-acid battery though bulky stability are much stronger than lithium batteries! Basic cost to accept! Stability and safety and the cost will be higher than that of lithium electricity! As long as it is either lithium battery, lead acid battery or is a kind of heavily polluting goods!

Lead-acid battery is "cheap", or "fake affordable"?

Buy something we're all going to be a comparison of the various aspects to have a comprehensive understanding, buy electric cars, too, for example: maintenance in the future, loss, replace the battery charging and discharging, etc., will spend a lot of money in the future!

Accord to understanding: general consumer of electric vehicle replaces cycle around four to five years. Lead-acid battery although cheap, but in high loss, often need to change once a year. Generally speaking, the better the lead-acid battery price is 600 yuan, so in the same car electric, only replace the batteries will cost about 2400 yuan.

Look at the configuration of lithium battery electric vehicles. Buy a lithium battery electric vehicle is about 3500 yuan. Lithium battery warranty 3 years or so, that is to say, in the three years we don't have to spend money to replace other batteries. And lithium battery life is very long, generally in 5 years. That is to say, in fact as long as we always take care yourself, don't again within five years in the electric vehicle is the cost of the other.

Currently selling electric cars, all battery brand, style or brand vary widely, and lead acid battery and lithium battery occupy the dominant position, here small make up by comparing to get you more clearly the relationship and difference between the two.

Typically, lead-acid battery in 16-30 kg weight, volume is larger; And lithium battery weight is in commonly 2.5 3.0 kg, volume is relatively small, so light and handling convenient also. Both from a quality point of view, good or bad it is difficult to define, but consumers can according to own actual need to purchase normal manufacturer production of the battery with good quality.

Lithium battery cathode materials, anode materials, set fluid, membrane, electrolyte advocate material costs a lot higher than lead acid battery. The lead-acid battery assembly and auxiliary material cost is very low and the external circuit system.

Because of making craft, lithium battery of artificial cost is larger. In manufacturing costs, labor costs accounted for more than 40%, lithium-ion batteries, and lead-acid battery of artificial cost is commonly 10% ~ 20%.

Lithium battery production equipment expensive, high value, mechanical equipment depreciation loss is bigger. Most of the lithium-ion batteries in the production process is irreversible, and lead-acid battery is reversible repair and used again. Lead-acid battery use after the recovery value of over 40%, and lithium battery recycling value is almost zero.

Lithium battery has energy volume ratio, and weight than energy, lithium batteries are more than three times that of lead-acid batteries. Lithium battery has smaller volume, lighter in weight and long cycle life. The cycle life of lithium batteries for electric vehicles is in commonly 800 times or more, using lithium iron phosphate cathode material of lithium battery can reach 2000 times or so, beyond the lead-acid battery 1.5 ~ 5 times. This greatly reduces the lithium-ion batteries use cost, prolong the service life and improve the use convenience degree with a wide range of charging effect. This is lithium battery has unique advantages. When necessary, can make the charging time control in 20 min ~ 1 h, charging efficiency above 84%.On the basis of further technological innovation, this feature will be better.

As we know, general contrast energy storage products from the weight energy density, energy density, volume, price, service life of applicability, angles such as national policy to:

The weight energy density

Current lithium battery energy density is in commonly 200 ~ 200 Wh/g, lead acid is in commonly 50 ~ 70 Wh/g, then the weight energy density of lithium battery is lead-acid 3 ~ 5 times, this means that under the condition of same capacity, lead-acid battery is lithium battery of 3 ~ 5 times, so the energy storage device on the lightweight, lithium battery occupy absolute advantage.

The volume energy density

The volume of a lithium battery capacity density is usually around 1.5 times of lead-acid battery, so under the condition of same capacity, lithium battery about 30% smaller than the lead-acid battery volume.

Use cycle

At present more popular material system is three yuan and lithium iron, three yuan power type lithium battery cycles are usually in more than 1000 times, lithium iron phosphate batteries cycles in more than 2000 times, lead-acid battery cycles are usually only about 300 ~ 350 times, so the service life of the lithium battery around three to six times that of lead-acid batteries.

The price

Lithium-ion battery is about three times more expensive than lead-acid battery. Considering the analysis of cycle life, lithium-ion battery has longer cycle life if they have the same cost.
