The main differences between lead-acid batteries and lithium batteries are different lifespan, number of charge and discharge cycles, volume and weight.
1. Different lifespans
The lifespan of lead-acid batteries is generally about 2 years, and lithium batteries have strong durability and are used. The lifespan is generally 4 to 5 years.
2. The number of charge and discharge cycles is different
Lead-acid batteries are generally fully charged and discharged in 400 times and have memory for; lithium batteries are fully charged and discharged 500 times and no memory.
3. Different sizes and weights
Typically, lead-acid batteries weigh between 16 and 30 kg and are generally larger than lithium batteries; -3 Kilogram, the volume is relatively smallt.
How lead-acid batteries and lithium batteries work:
Lithium-ion batteries are characterized by their lightness and ease of transport. Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
Lead-acid batteries can store limited electrical energy and use it in appropriate locations. Its working principle is to convert chemical energy into electrical energy. It uses a lead plate filled with sponge lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22 to 28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy and during discharging, chemical energy is converted into electrical energy.
What is the besteur, a lead-acid battery or a lithium battery?
The most common electric vehicle batteries on the market today are lithium batteries and lead-acid batteries. , whether it is lead-acid batteries or lithium batteries, they have their own advantages and disadvantages, so there is no way to say which is better, I can only say which one is more suitable for you. After all, everyone's use situation is different. It is recommended to refer to lead-acid batteries and lithium batteries. Based on the advantages and disadvantages of the battery, combined with your actual usage, you can choose an electric vehicle battery that suits you better. 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 andDon't 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 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 compact sizeSmall. The volumee 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 dischargedge 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 to 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.
Depending on product quality, after-sales service andprice, we recommend several relatively good lead-acid battery brands: Changxin Battery, Shinhwa Battery, and Mantingfang Battery.
What are the differences between lead acid and lithium batteries for electric vehicles?
Lead acid batteries and lithium batteries, lithium batteries are better.
1. Energy density: The energy density of lithium batteries is generally higher than that of lead-acid batteries, which means that with the same weight, lithium batteries can store more energy and provide longer driving distances. Therefore, lithium batteries may be more suitable for applications requiring long-term driving or requiring light weight.
2. Lifespan: The lifespan of lead-acid batteries is relatively short, generally around 2-3 years, while the lifespan of lithium batteries is longerongue, usually around 5 to 6 years or more. Therefore, in terms of service life, lithium batteries have advantages.
3. Environmental protection: Lead-acid batteries contain harmful substances such as lead, which will cause environmental pollution if not handled properly. Lithium batteries do not contain harmful substances like lead and are more environmentally friendly. For environmentally friendly applications, lithium batteries are a better choice.
The difference between lead acid batteries and lithium batteries for electric vehicles is as follows -
1. Different concepts
Lead-acid batteries ( VRLA) are The first electrode mainly consists of lead and its oxide, and the electrolyte is a sulfuric acid solution battery.
The lithium battery is a type of battery thatuses lithium metal or lithium alloy as the negative electrode material, and uses non-aqueous electrolyte solution.
2. Different Durability
Lead-acid batteries generally have a deep charge and a deep discharge of 30.In 0 times, it has memory and its life is about two years. And there is liquid in the lead acid battery. After a period of consumption, the liquid needs to be replenished;
Lithium batteries have strong durability, slow consumption, can be charged and discharged more than 500 times. and have no memory. The general lifespan is 4 to 5 years.
3. Different volume and quality
Typically, lead acid batteries weigh between 16 and 30 kg and are larger
Lithium batteries generally weigh between 2.5 and 3000 kg. 3 kilograms, the volume is relatively small.
4. Different prices and warranty periods
Lead-acid batteries costabout 450 yuan and the warranty period is 1 year
Lithium batteries are relatively expensive and; require It costs about 1,000 yuan, but the warranty period is two years.
5. Different battery capacities
The capacity of lead acid battery is about 20 amps; Lithium battery capacity is 8-10 amps.
6. Environmental protection is different
Lead-acid batteries contain pollution during the production process and may cause pollution if improperly recycled.
Lithium batteries are relatively polluting; green and environmentally friendly.
