The difference between lithium batteries and lead acid batteries is: different weight, different lifespan and different battery capacity.
1. The weight is different. The weight of the lithium battery is only 1/4 of that of the lead-acid battery of the same capacity, and the volume is only 1/3 of that of the lead-acid battery. lead acid battery of the same capacity.
2. The lifespan is different. The lifespan of lead-acid batteries is typically around 2 years, while lithium batteries are more durable, with a lifespan of 4-5 years. The lead-acid battery cycle is generally fully charged in 300 times, while the lithium battery is fully charged and discharged more than 500 times.
3. Battery capacity is different from lead-acid batteries, lithium batteries have higher average operating voltage and higher specific energyus high. In other words, for the same size rechargeable batteries, lithium batteries. have greater capacity.
Applications of lithium batteries:
Lithium batteries are widely used in energy storage systems such as hydropower, l thermal energy, wind energy and solar power plants. , and uninterrupted postal communications and telecommunications Power supplies, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.
Lithium-ion batteries have been widely used in portable devices such as laptops, cameras and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery has been tested in electric vehicles and has become one ofs main energy sources for electric vehicles in the 21st century. It will also be used in satellites, aerospace and energy storage.
With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of lithium battery industry.
The difference between storage batteries and lithium batteries
Lithium ion batteries are lightweight and have high specific energy, but they are safe and profitable.
Lithium-ion batteries are rechargeable batteries, while lead-acid batteries are alkaline batteries: lithium-ion batteries have a lifespan of more than 2,500 times, and lead-acid batteries lead have a lifespan of approximately 800 times. fois. In other words, for the same weight, lithium batteries can travel further than lead acid batteries. Therefore, in terms of energy density, lithium batteries are better than lead-acid batteries.
From a lifespan perspective, a set of good quality lithium batteries can be cycled about 1,000 times, while lead acid batteries are only about one third of that of lithium batteries. Therefore, in terms of service life, lithium batteries are better than lead-acid batteries.
Lead-acid battery
1: (Hard!) The lead-acid boss has always been strong and allowed others to be strong, and the breeze blew on the hills . He lets others do what he wants, and the bright moon shines on the river as a principle. Lead-acid batteries are easy to maintain. You can knock them over, fix them a little and continue to use them.
2 : (Cheap!) The reason why the main boss was able to dominate the battery community for many years and sit as boss is entirely due to this cheap reason! Besides being cheap, it's still cheap.
: (Recyclable and reverse repair) Lead-acid batteries have built-in recyclability skills
After use, you can go to the electric livestock store to exchange them for new ones
p>< p>You can replace it with a new set of batteries by paying the price difference, thus minimizing losses. This is a great advantage for users.
Lithium battery:
1: (light, small size) Lithium battery developed since childhood
Lead acid battery with the same capacity on the market In comparison, the volume of lithium battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid batterylead. Lithium batteries of the same volume have a higher capacity than lead acid batteries. Reducing weight increases the range of electric vehicles by approximately 1
0%.
2: (Increased lifespan) Lithium batteries are well known for their health. The average lifespan of lithium batteries is about one year, about 1.5 times longer than lead-acid batteries. charged and discharged more than 500 times, and the battery will last forever. Memory, strong resistance to earthquakes.
3: (Resistance to overcharge, good resistance to charge and discharge) Lithium batteries have opened the eight extra meridians since childhood, so that at normal temperatures, the Lithium batteries can be continuously charged for 48 hours without battery. Expansion and leakage In case of accidents such as liquid rupture, the capacity remains above 95%. And with a special charger, il can be loaded and unloaded quickly.
The production cost of lithium batteries is high, and the production equipment is expensive and labor costs account for
about 40% of the production cost . The price is about three times that of lithium batteries. lead-acid batteries. At three times the price, the quality/price ratio is not very high. It looks rather flashy and the lithium 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.
Which is better: lithium battery or storage battery?
Look for cost-effectiveness and choose lead-acid batteries.
If you use electric vehicles, you pay more attention to profitability, which means they are more economical. There is no doubt that theLead acid batteries are the first choice. say that? For me, lead acid batteries have 3 advantages, you will understand.
Advantage 1: Low price. 75% of lead acid batteries are lead plates, and lead metal is much cheaper than lithium metal. The electrolyte in lead-acid batteries is a fusion of sulfuric acid and water. The electrolyte of lithium batteries is composed of lithium salts and organic solvents, and the manufacturing process will be higher. Therefore, the purchase price of lead-acid batteries is very low, about one third of that of lithium batteries.
Advantage 2: Repairable. Compared with lithium batteries, which are disposable batteries and can only be replaced in the event of a breakdown, lead-acid batteries can be replenished if the electrolyte loses water, and the aging battery can be repaired . Thanks to pulse technology. As a repairable battery, it is easierto use with high performance.
Advantage 3: Recyclable. Once lead-acid batteries are discarded, they are not “waste” but have a high reuse value. Therefore, many companies recycle or exchange discarded lead-acid batteries. , its recycling price is about a third of that of a new battery.
The above three points are enough to highlight the affordable price of lead-acid batteries. Therefore, if you are looking for cost-effectiveness in batteries, it is recommended to choose lead-acid batteries. Of course, lithium batteries are one of them. traditional batteries, and they are not “useless”.
In terms of performance, scope of application and degree of environmental pollution, lithium batteries are better batteries thanacid batteries. leadfor specific reasons Let me discuss it with you a par one 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 difference 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 battery charging.memory 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 battery life
3) Resistant to overcharging
Qualified lithium batteries can be charged continuously at normal temperatures. There will be no serious problems such as expansion, leakage or breakage of the batbattery within 48 hours, but lead-acid batteries cannot suffer from such overcharging, which would 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.
Lithium batteries are more widely used
3. Lithium batteries cause less environmental pollution
In terms of environmental pollution Compared to lead. -Lithium batteries arecleaner 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. will cause a lot of damage to the environment.Impact, even though lead-acid batteries can be recycled, heavy metal pollution is still a serious problem.
In summary, lithium batteries are better than lead acid batteries in terms of performance, application and environmental impact. However, the shortcomings of lithium batteries are also obvious. For example, the safety of lithium batteries is poor, especially low-quality ones, which pose explosion and fire risks. Production conditions are demanding and the cost is high. the selling price is therefore naturally higher than that of lead, and lead batteriesithium 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.
