Lithium batteries are good.
1. From a lifespan perspective, lithium batteries have a longer lifespan, while storage batteries have a relatively shorter lifespan. The number of cycles of lithium batteries is 2000-3000 times; the number of cycles of storage batteries is 300-500 times.
2. From the perspective of environmental protection, lithium battery materials do not contain any toxic or harmful substances and are regarded as green batteries by the world. The batteries are pollution-free both in their production and in their use. with European RoHS regulations and are environmentally friendly batteries; There is a large amount of lead in the battery, which will pollute the environment if not handled properly after disposal.
The choice of an electric vehicle battery, a batrie lead acid or lithium battery, mainly depends on your own needs. Whether lead-acid batteries or lithium batteries, they have their own advantages and disadvantages, so there is no way to say which is better. We can only say which one is best for you. After all, everyone's usage situation is the same. different. You can refer to lead acid batteries. The advantages and disadvantages of batteries and lithium batteries, combined with your actual use, 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-io batteriesn, 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. Battery lead can also be recycled and reused, reducing environmental pollution.
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 overcharge, 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 equipment ofProduction is expensive and labor costs represent approximately 40% of the production cost. The price is about three times that of lead-acid batteries. for three times the priceThe price/performance ratio is not high, and it looks rather flashy, and the lithium-ion battery is not recyclable. Once worn out, you can only throw it away or find a place to bury it after thousands of years. future generations will dig it up and it will be an antique.
