In terms of performance, scope of application and degree of environmental pollution, lithium batteries are better batteries thanlead-acid batteries. The specific reasons will be discussed here.
1. The performance of lithium batteries is better
The performance of lithium batteries is mainly reflected in the following three aspects. :
1) Service life
The lithium battery has good temperature performance and can be used at relatively low temperatures and can also be normally used at high temperatures and does not affect the service life, so lithium batteries have a longer service life than lead-acid batteries. Usually, lithium batteries have a lifespan of more than 6 years, while the average lifespan of lead-acid batteries is only about 2 years. a differencee of almost 3 times is certainly an advantage.
Another point is that lithium batteries do not have battery memory effect, so there will be no reduction in battery capacity caused by memory charging like lead-acid batteries.
Lithium batteries have a long lifespan
2) Battery life
Lithium batteries have very high storage energy density and therefore due to the high voltage platform it is easy to form a battery power pack for use in various devices. Lithium batteries are small in size and charge relatively quickly, while lead-acid batteries are large in size, charge slowly, and consume power quickly, so the battery life is much less than that of lithium batteries.
Lithium batteries have good autonomy
3) Resistant to overcharging
Qualified lithium batteries can be continuously charged at normal temperatures. There will be no serious problems such as battery expansion, leakage or rupture within 48 hours, but lead-acid batteries cannot suffer from such overcharging, which will cause serious consequences.
Resistant to overload
2. Lithium batteries have a wider range of applications
Lithium batteries are lightweight and relatively small. in size, easy to carry, which determines that lithium batteries of the same volume can have higher capacity than lead-acid batteries, which can improve the endurance of related equipment, so that they can be used in more fields, such as electric vehicles, mobile phones, cameras and other electronic supplies, etc.
The batteriesithium are more widely used
3. Lithium batteries cause less environmental pollution
In terms of environmental pollution Compared to lead. -Lithium batteries are cleaner and more environmentally friendly. Lithium batteries do not contain heavy metals such as lead and mercury. They will not cause major environmental pollution during production, use and disposal. This will cause a lot of damage to the environment. A big impact, although lead-acid batteries can be recycled, heavy metal pollution remains a serious problem.
In summary, lithium batteries are better than lead acid batteries in terms of performance, application and environmental impact. But the shortcomings of lithium batteries are also obvious, such as lithium battery safety is poor, especially thes poor quality lithium batteries, which pose a risk of explosion and fire. The production conditions are demanding and the cost is high, so the price is naturally much higher than that of lead, and lithium batteries cannot. be recycled.
Lithium batteries also have many disadvantages
So even though most of the conditions of lithium batteries are better than lead acid batteries, you should always choose according to your actual situation. A battery that suits you.
What are the differences between lead acid batteries and lithium batteries for electric vehicles?
The difference between lithium batteries and batteries is:
1. Safety performance: Lithium batteries come from the stability and reliable safety design of positive electrode material and phoslithium iron phate. the batteries have passed strict safety tests. The security test shows that the security is very high. The battery is a lead-acid battery, which will explode in a strong collision, posing a threat to consumer safety.
2. The prices are different: lithium batteries are more expensive, about three times more expensive than batteries. Batteries are cheaper and have a shorter lifespan.
What is the difference between lithium batteries and lead-acid batteries?
The differences between lead-acid batteries and lithium batteries for electric vehicles are as follows :——
1. Different concepts
The lead-acid battery (VRLA) is a battery whose electrodes consist mainly of lead and its oxides, and the electrolyte is a solution of sulfuric acid.
Lithium battery is a type of battery that uses lithium metalor lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
2. Different durability
Lead-acid batteries are generally deeply charged and discharged 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, 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 cost about 450 yuan and the periodThe warranty 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.

1. Advantages of Lithium Batteries
1 The rated life of lead-acid batteries is generally 2 to 3 years. When used under the same conditions, the lifespan of a new lithium-io batteryn is usually around 4 to 5 years. Of course, this is just a theory. The actual lifespan varies depending on people's usage habits.
2. Lithium batteries have no memory effect. Regardless of the battery condition, it can be charged and used at any time. Most batteries need to be charged after the battery is exhausted to avoid memory effects.
3. The volume of lithium battery is about 2/3 of that of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery.
2. Advantages of lead acid batteries
1. The price is close to people and there are special channels for recycling old batteries. With the same capacity, the surface price of lithium batteries is about three times that of lithium batteries. Although the lifespan of lithium batteries is theoretically three times longer than that of lead acid batteries, itit only seems to compensate for itself. costs more in the initial investment. In fact, an important factor has not been taken into account, namely that the lithium battery is currently broken and there are practically no recycling channels. Even if it is available, it cannot be sold. a lot of money, while lead-acid batteries can recoup at least around 30% of the price of a new battery. Although lead-acid batteries typically only last about a year and a half, lithium batteries still deteriorate after two years of use. I replaced them with new lead acid batteries and they can regain their vitality. However, still-old lead-acid batteries are still a bargain in comparison, at least for ordinary people commuting to and from work.
2. The cruise range can meet daily use. With the same volume, lithium batteries cannt run further, but when the mileage increases, the cost also increases, and the effect is not very obvious to ordinary people traveling to or from work, or shopping. It is found everywhere in town. The charging socket can be charged at home overnight, which is usually sufficient. If you need it temporarily, you can also get it at work or at a friend's house. for nearby transport. If you are a little further away, you can take a car or drive a 4x4.
3. Easy to replace. There is no management system for lead-acid batteries. If they break down, simply replace them. Lithium batteries are too delicate. You need to protect the card etc. There does not appear to be a unified standard in the market. If it breaks, you usually have to return it to the manufacturer. is not just for yourself. It is convenient. If it breaks, yous can find accessories anywhere. If it breaks, you must return it to the manufacturer for processing.
4. Safe and reliable. A lot of news about the explosion of electric vehicles is related to lithium batteries, and lead-acid batteries basically eliminate this possibility. This is also an important reason why lead acid batteries can last a long time.
