It is also an energy storage battery. Why do more solar lithium-ion batteries choose lead-acid batteries?

It is also an energy storage battery, why choose solar lithium ion batteries more than lead-acid batteries? Solar street lights are currently developing relatively rapidly. Lithium ion batteries are a kind of controllable and pollution-free energy storage battery, a new type of lithium ion The battery solar street light can perfectly match the system. As the technology of lithium-ion batteries becomes more and more mature, the capacity becomes larger, the lifespan is longer and longer, and the scope of application becomes wider. Now the use of lithium-ion batteries has been carried out to the solar street lamp profession, replacing lead-acid and gel batteries. Why do so many people choose solar lithium-ion batteries?

1. Lithium-ion battery:

There is no doubt that it is better than lead-acid batteries in terms of performance. At present, the common one is lithium iron phosphate batteries. This battery does not have a memory effect like lead-acid batteries. After more than 1600 charges, the battery’s storage capacity It can still reach 85%. Compared with lead-acid batteries, lithium-ion batteries have the advantages of lightness, large capacity, and long service life.

2. Lead-acid battery:

The electrode is mainly made of lead and oxide, and the electrolyte is a sulfuric acid solution. In the charged state of lead-acid batteries, the important component of the positive electrode is lead dioxide and the important component of the negative electrode is lead; in the discharged state, the important components of the positive and negative electrodes are lead sulfate. Because of the memory effect of lead-acid batteries, the storage capacity of the battery will be greatly reduced when overlapped more than 500 times.

Therefore, many customers also highly approve of Baoding lithium-ion battery solar street lights. This is the reason why solar lithium-ion battery street lights are becoming more and more popular.

Third, why choose solar lithium-ion batteries more than lead-acid batteries?

△Lithium-ion battery is small in size and light in weight, and the device saves time and effort

Now the first choice for solar street lights in the world is generally integrated street lights. If lead-acid battery packs are used, they should be buried underground around the light poles and placed in the buried box. If lithium-ion batteries are used, they have to rely on their lighter weight. , It can be connected to the back of the battery board, saving time and effort.

△Lithium-ion batteries have less pollution than lead-acid batteries and are green

We all know that lead-acid batteries have a relatively short service life. Although they are cheap, they may need to be replaced once a year, which will greatly increase environmental pollution. In addition, lead-acid batteries are more polluting than lithium-ion batteries. If they are replaced all the time, they will always cause harm to the environment. Lithium-ion batteries are not polluted, while lead-acid batteries are polluted by heavy metal lead.

△Lithium-ion battery is smarter

Today's lithium-ion batteries have become more and more intelligent, and their functions have become more and more complete. The current lithium-ion battery can be adjusted according to the user's demand for the battery, the length of use, and so on. Many lithium-ion batteries can be installed with a BMS management system, which can view the battery status on the mobile phone in real time, and can also detect the current and voltage of the battery autonomously. If there is an abnormal situation, the BMS system can automatically adjust it.

△Lithium-ion battery has longer service life

The annual loss of lead-acid batteries is relatively high, and they are often replaced once a year or two. The lithium-ion battery has a service life of 35 years, and generally it can be guaranteed for three years. The cycle life of lead-acid batteries is about 300 times. The lithium iron phosphate battery has a 3C cycle life of more than 800 times.

△Lithium-ion battery is safer and has no memory effect

Lead-acid batteries are easy to enter water, and lithium-ion batteries are not easy to enter water. Moreover, lead-acid batteries have memory properties, that is, when they are not fully discharged, they will have a memory effect, which will affect the service life of the battery. The lithium-ion battery has no memory and can be recharged at any time. This is safer and more reassuring to use. Lithium iron phosphate has passed strict safety tests and will not explode even in severe collisions.

△Lithium-ion battery has high energy density

Lithium-ion batteries have a high storage energy density, which has now reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. This will better store energy for solar street lights.

△Lithium-ion battery solar street light is very high temperature resistant

Solar street lights are exposed to the sun every day, so there are higher requirements for the temperature environment. The thermal peak of lithium iron phosphate battery can be 350~500℃, and it can be used in the environment of -20℃--60℃.

△Price and warranty period

At present, the mainstream battery on the market is 48 volts. If replaced, the lead-acid battery is about 450 yuan, and the warranty period is 1 year; the price of lithium ion batteries is relatively expensive, about 1,000 yuan, but the warranty period is two years.

4. In general, the advantages of solar lithium-ion battery street lights:

1. Adjustable solar panel support to maximize light collection;

2. Green and environmental protection;

3. Lithium-ion battery is convenient to install directly under the solar panel, small size and light weight, reducing construction cost;

4. Long service life is 3-5 times that of traditional energy storage lead-acid batteries;

5. The resistance to high and low temperature can be used in the environment of -20℃-60℃, and the special process of Seiko can be used in the environment of -45℃;

6. Good maintenance-free performance.

Energy Storage Electric Lithium Iron Phosphate Battery Pack

Summary: The above is the introduction of the advantages of lithium-ion batteries for solar street lights compared to lead-acid batteries. Lithium-ion batteries are a controllable and non-polluting energy storage battery, which is more stable and safer than lead-acid batteries. . Lithium-ion battery solar street lights are more popular with customers, and Baoding lithium-ion battery solar street lights are also highly recognized. Lithium-ion battery solar street lights have become a development trend, and there will be more and more solar street lights choosing lithium-ion batteries as energy storage devices in the future.
