Which is better, a lithium-ion power bank or a lithium battery?

Introduction Which is better, a lithium-ion power bank or a lithium battery? You asked this question in a very strange way. . Generally, power banks are lithium-ion batteries. The difference is that there are two types of batteries: one is a cylindrical steel shell 1.

Which is better, a lithium-ion power bank or a lithium battery?

That's a strange question. . Generally, external batteries are lithium-ion batteries. The difference is that there are two types of batteries inside: one is a cylindrical steel case 18650 lithium battery; the other is a lithium polymer battery;

Both are lithium. -ionic batteries. , it’s just that the electrolyte is different and the structure is different; but both are lithium batteries, because the materials of both are lithium-ion materials

Whether it is a lead-acid battery. battery or a lithium battery, each has its own advantages and disadvantages, so there is no way to tell which is better. We can only say which one is best for you. After all, everyone's terms of use are different. Refer to the advantages and disadvantages of lead-acid batteries and lithium batteries and combine them with yours. Depending on theactual use situation, choose the electric vehicle battery that suits you best. Here are their respective advantages and disadvantages:

Advantages of lead acid batteries:

1. Good safety performance. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.

2. Cheap price. The price of lead-acid batteries is about 1/3 that of lithium-ion batteries, which shows how low the price is.

3. Recyclable reverse repair. Lead acid batteries are highly recyclable. Once worn out, you can go to an electric car store to exchange them for new ones. You can exchange them for a new set of batteries by paying the price difference, thus minimizing losses. a great advantage for users. The lead from the battery can also be recycled and reused, reducing environmental pollution.nment.

Disadvantages of lead-acid batteries: high weight, limited battery capacity and short lifespan. Lead-acid batteries typically have a lifespan of about three years after 400 deep charges and discharges.

Advantages of lithium-ion batteries:

1: Lightweight and small size. The volume of lithium-ion battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery. Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries. The reduced weight makes electric vehicles lighter and their range is increased by around 10%.

2: Long life. The average lifespan of lithium-ion batteries is about 4 years, about a year longer than lead-acid batteries. It can be charged and discharged more than 500 times. The battery has no memory and is very shock resistant.

3: Resistant to overheatingrge, good resistance to charge and discharge. At normal temperatures, lithium-ion batteries can be continuously charged for 48 hours without causing expansion, leakage, rupture or other accidents, and the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.

Disadvantages of lithium-ion batteries:

The production cost of lithium-ion batteries is high, the production equipment is expensive, and the labor costs represent approximately 40% of the production cost. The price is about three times that of lead-acid batteries. At three times the price, it's not great value for money, and it looks rather flashy. Additionally, lithium-ion batteries are not recyclable. Once worn out, they can only be thrown away or buried after thousands of times. years, future generations will not be able to use them. If you dig it up, it will be an antiqueity.

Based on the quality, after-sales service and price of electric vehicle battery products, we recommend several good lead-acid battery brands: Tianneng Battery, Changxin Battery, Shinhwa Battery , Man Tingfang Battery.
