- Nowadays, the application of lithium batteries is quite extensive. We can see them not only on smart hardware such as mobile phones and computers, but also as the main power source for electric bicycles. So why does a lithium battery become a mainstay?
Do you know why electric vehicles use lithium batteries? Today's power adapter manufacturers are secret for everyone, electric vehicles need to use lithium batteries? Today, the application of lithium batteries is more extensive, we are not only on mobile phones, computers and other intelligent hardware It can be seen that electric bicycles also use it as the main source of power. So why does a lithium battery become a mainstay?
In fact, to say the cost or price, lead-acid batteries are cheaper than the high cost of lithium batteries. A lead-acid battery is only 200 to 300 yuan. 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 replaced in 2-3 years. New, so to provide more power for electric vehicles, lead acid is clearly not the first choice.
It is true that nickel-metal hydride batteries, which are also mentioned by people, do have more powerful energy density and battery performance than factors such as low energy density and short battery life of lead-acid batteries. 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.
Lithium battery, because lithium battery not only has 2000 times higher 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, so for the current pure electric vehicle The industry is ideal. Nowadays, lithium batteries are widely used in power tools, electric bicycles, electric motorcycles, electric vehicles and other fields, in addition to their excellent performance in portable appliances 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.
As a professional power adapter manufacturer, Shenzhen Lianyunda Electronics produces a wide range of lithium battery power adapters, such as electric vehicles, balance cars, and notebooks. These are suitable for charging lithium battery products. They are highly efficient and safe, and can better extend lithium batteries. The service life.
