Many things in our lives require electricity, but as we all know, the most commonly used batteries in our lives are ordinary batteries and lithium batteries. But relatively speaking, what are the specific differences between ordinary batteries and lithium batteries? I think most people don't know this. With the development of modern high technology, it has become more and more convenient for everyone to travel. Every household will buy a small and light electric vehicle for themselves. If you haven't purchased one, you can see many shared electric vehicles available for rental. by the side of the road. So everyone Do you know how to choose an electric vehicle battery? ?
Ordinary batteries can be divided into carbon batteries and alkaline batteries, which are our most commonly used dry batteries, and hydrochloric acid batteries. SO,what is a lithium battery? In fact, a lithium battery is a battery made of negative electrode material mixed with metallic lithium and other synthetic metals and then combined with a non-aqueous electrolyte solution. So, does everyone know the difference between regular batteries and lithium batteries? In fact, we use a lot of lithium batteries these days. For example, cell phone batteries are lithium batteries. Compared with ordinary batteries, lithium batteries have smaller internal resistance, so their service life will be better.
The question then is: if we want to buy an electric bike, what type of battery should we choose? Is it better to buy an electric car with a lithium battery or a car with a regular battery? Actually, I think this question is very simple. Everyone will understand that batterieslithium are of course better, although most electric vehicles on the market are equipped with lead-acid batteries, which are ordinary batteries, compared to lead-acid batteries. Speaking, the lifespan of lithium batteries will be higher.
Lithium batteries can be charged and discharged more than 600 times, but if a lead acid battery reaches 600 charges and discharges, then I think the battery must be very tired. At that point, there must be a lot of virtual. electricity in the battery. Additionally, lithium batteries are lighter than lead-acid batteries, so e-bikes with lithium batteries will be lighter than e-bikes with lead-acid batteries.What are the differences between the advantages of lead-acid batteries and lithium batteries?
The differences between lead-acid batteries and lithium batteries:< p>1. Durability: batteryLead-acid ies are generally charged and discharged deep within 300 times, have memory, and have a lifespan of about two years. And there is liquid in the lead acid battery. After a period of consumption, if you find that the battery is hot or the charging time becomes shorter, you should replenish the liquid. Lithium batteries have strong durability, slow consumption, can be. charged and discharged more than 500 times and has no memory. Generally, the lifespan is 4 to 5 years.
2. In terms of volume and quality: In general, lead-acid batteries weigh between 16 and 30 kg and are relatively bulky; Lithium batteries typically weigh between 2.5 and 3 kg and are relatively small, so they are light to drive and easy to transport.
3. Price and warranty period: The common battery in the market is 48 volts. If replaced, lead acid batteries cost approx.n 450 yuan and the warranty period is 1 year. costs 1,000 yuan. It costs about 100 yuan, but the warranty period is two years.
4. Miles Traveled: This is also a 48 volt battery. When fully charged, electric vehicles equipped with lead-acid batteries and lithium batteries can travel 30 to 40 kilometers. The speed mainly depends on the size of the motor used.
5. Battery Capacity: Lead acid battery capacity is about 20 amps; Lithium battery capacity is 8-10 amps.
6. Environmental protection: Lead-acid batteries are polluting during the production process and may cause pollution if not recycled properly; Lithium batteries are relatively green and environmentally friendly.
What are the advantages of lead-acid batteries and lithium batteries?
The beatsCommon electric vehicle series currently on the market are lead-acid batteries and lithium batteries. Here are their respective advantages and disadvantages, you can refer to them:
Lead-acid batteries Advantages of 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. Battery lead can also be recykeyed and reused, thereby 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 isvery resistant to shocks.
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 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 toDon't use them. If you dig it up, it will be an antique.
The safety performance of lithium batteries is worse than that of lead-acid batteries, especially at high temperatures, they are prone to dangers such as fire, spontaneous combustion and explosion.
Based on the quality, after-sales service and price of electric vehicle battery products, we recommend several good lead-acid battery brands: Changxin Battery, Shinhwa Battery and Mantingfang Battery .
According to the current trend, the performance of lithium batteries is significantly better than that of lead-acid batteries. Long life: The charge and discharge rate of lithium-ion. the batteries are 1C. Its lifespan is greater than or equal to 500 times. However, even if the lead-acid battery is discharged to 0.5c and charged to 0.15c, its life is less than or equal to 350 times and its capacity est less than or equal to 60%.
2. Good low temperature discharge performance: Lithium-ion batteries can work normally at -25°C and the capacity can reach 70%, while lead-acid batteries can reach 50% of the capacity at -25°C. 10°C But it cannot work properly at -25℃.
3. Strong charging capacity: After 2 months of a fully charged lithium-ion battery, its capacity is 80% or more, while a lead-acid battery is only 40% capacity. nominal capacity after 2 months of rest.
4. Strong endurance. The weight of lithium-ion batteries is only 30% of that of lead-acid batteries, so under the same voltage and capacity, lithium-ion batteries have greater durability.
5. High specific energy: Since the volume of lithium-ion batteries is only 30% of the volume of lead-acid batteries, the energy reserve of lithium-ion batteriesn is higher than that of lead-acid batteries. Batteries in the same use of space.
6. Wide operating temperature range: Lithium-ion batteries can operate in the range of -25c to 55c, while lead-acid batteries can only operate in the range of 10c to 40c.
7. Short charging time: Lithium-ion batteries can be charged with high current and the charging time is only 4-5 hours, while lead-acid batteries take 8-10 hours.
8. High environmental protection performance: Compared with lead-acid batteries, lithium-ion batteries are very environmentally friendly products. They contain a large amount of lead, a heavy metal, harmful to the human body. and the environment.
9. Large Current Discharge: Lithium-ion batteries discharge large current at 1C and the capacity is only 60% of the rated capacity.
10. High current discharge does not affect service life: High current discharge of 1.5c multiplier of lithium-ion battery does not affect service life. However, lead acid batteries discharge at a high current rate of 1.5c. Its lifespan only represents 30 to 40% of the nominal lifespan.
