Why use lithium batteries for electric vehicles

As the "energy source" of all kinds of electronic intelligent devices that we are most familiar with, the application fields of lithium batteries can be described as quite wide, not only in smart hardware such as mobile phones and computers, but nowadays more and more electric bicycles are used in addition to lead acid. In addition, lithium batteries are generally used as the main source of power. Therefore, it is not an exaggeration to say that lithium batteries are "good quality and low price" in the battery industry. But the question arises: Is lithium batteries really irreplaceable?

In fact, to say the cost or price, compared to the high cost of lithium battery, lead-acid battery is cheaper? Is it 2 - 300 yuan price can change your own electric car to a lead-acid battery at any time, it is quite cost-effective. But everyone knows that lead-acid batteries also have some shortcomings. For example, lead-acid batteries have relatively low energy density, short battery life, and long life. The battery cycle is 300-500 times. It has to be changed in 2-3 years. New, so to provide more power for electric vehicles, lead acid is clearly not the first choice.

Let me talk about the nickel-metal hydride battery that is also mentioned. Indeed, nickel-hydrogen batteries have more powerful energy density and battery performance than factors such as low energy density of lead-acid batteries and short battery life. For example, the same volume of nickel-metal hydride battery is almost twice as powerful as lead-acid battery, and its battery life is more durable. It is lighter to carry and the battery cycle can reach 1000 times. It is quite powerful. But the same, the shortcomings of nickel-metal hydride batteries - memory effect, overcharge and over-discharge will make the battery capacity recurring attenuation will increase, so to be the ideal battery power for electric vehicles, nickel-metal hydride batteries are also not the first choice.

Let's talk about the protagonist of this article - lithium battery, because lithium battery not only has 2000 times more battery cycle than nickel-hydrogen battery, but also has high energy density, and charge and discharge has little effect on its battery capacity, of course, the cost price is moderate. Therefore, it is an ideal choice for the pure electric vehicle industry.

Today, lithium batteries are widely used in power tools, electric bicycles, electric motorcycles, electric vehicles, etc., in addition to portable applications such as laptops, camcorders, and mobile communications. With the shortage of energy and environmental protection demand, lithium battery may have a more promising development in the electric vehicle industry.
