Lead-Acid Battery VS Lithium Battery VS Graphene Battery, Which is Better?
2022-09-236
As one of the commonly used means of transportation, electric mopeds should consider replacing the batteries every one or two years. With the popularity of electric mopeds, the batteries of their soul components are becoming more and more diversified. At present, the batteries on the market are mainly divided into: lead-acid batteries, lithium batteries, graphene batteries and nickel-metal hydride batteries.

 

However, due to some reasons such as technology and price, the mainstream batteries in the electric vehicle market are still lead-acid batteries and lithium batteries. So, among the many batteries, which type of battery is more cost-effective and more practical? This article will analyze them one by one.

 

First, analyze the safety performance of electric mopeds - lead-acid batteries are safer

 

It is not difficult to see cases of electric mopeds igniting spontaneously in life, and most of the reasons for tracing the origin come from lithium batteries. Because the lead plate and sulfuric acid in the lead-acid battery do not have the characteristics of deflagration, and there is no organic electrolyte, there is usually no spontaneous combustion; but the lithium battery is different. The lithium battery itself has a sealed space and organic matter is prone to appear. Thermal runaway with conditions for spontaneous combustion. In the event of improper charging or dangerous situations, electric mopeds with lead-acid batteries are relatively safer. From the perspective of safety, lead-acid batteries are a more cost-effective choice.

 


Analysis from the price level of electric mopeds - lead-acid batteries are cheaper

 

Electric mopeds with lead-acid batteries are usually cheaper than lithium-ion battery electric mopeds, with a price difference of several hundred yuan, or even more. For example, a set of 60V20Ah lead-acid batteries, the price is about 750 yuan, which is more widely used and more affordable than ordinary electric motorcycles of about 2500-3000 yuan. Moreover, the recycling value of lead-acid batteries is higher than that of lithium batteries, so from the perspective of price, lead-acid batteries have more advantages.

 

From the analysis of the service life of electric mopeds - lithium batteries have a long life, durable and not easy to break

 

The reason for changing the battery is because the battery is not durable. The biggest disadvantage of electric mopeds is that the battery is not durable and the battery life is not long. And lithium batteries happen to make up for this shortcoming.


 

Lithium batteries have high density, high energy and long battery life. For example, the lead-acid battery can be fully charged and discharged about 360 times, while the lithium battery can be charged and discharged about 1000 times, which is 3 times that of the former. And generally, the service life of lithium batteries can reach 3-5 years, which is about 1-3 years longer than lead-acid batteries, and lithium batteries are more durable. If you belong to the group of about 80-120 kilometers at a time, you can choose lithium batteries. From the analysis of the service life of electric mopeds, lithium batteries are a better choice.

 

From the practical analysis of electric mopeds - choose lead-acid batteries to pick up your baby at work, and choose lithium batteries for takeaways and long mileage

 

The practicality of electric mopeds is a key point for consumers. These two types of batteries have their own characteristics. It is still necessary to choose their own practical electric mopeds according to their own needs. For example, if you go to work far away, and the round-trip mileage is about 100 kilometers, considering the climbing and battery life, the lithium battery will be better; then if you only use it for daily riding, short-distance travel or picking up children nearby, choose lead An electric car with an acid battery will do.


 

Finally, briefly talk about graphene batteries. Some netizens complained: When will graphene batteries that have been blown for more than ten years land? In fact, for graphene batteries, there are different opinions in the market, and some people even think that this is just a publicity stunt by businesses. At present, the use of graphene batteries in the electric vehicle market is not as widely used as lead-acid batteries and lithium batteries. At present, a large number of mature products have not yet been put into the market. Here we are only for reference and look at its subsequent development.
