The same is the power battery. Why do more solar lithium batteries choose lead-acid batteries?

Again, why is solar energy instead of lead-acid batteries? At present, the development of solar street lights is relatively rapid. Lithium batteries are a controllable and pollution-free energy storage battery. The new type of lithium battery solar street lights can perfectly match the system. As the technology of lithium batteries becomes more and more mature, the capacity is larger and longer, the life span is longer and longer, and the application range is wider and wider. Lithium batteries have now been used in solar street lights, replacing lead-acid batteries and gel batteries. Why do so many people choose solar lithium batteries? Here is the editor of the energy storage battery to express my understanding of the two batteries, you can refer to it.

I. Lithium battery.

There is no doubt that it is superior to lead-acid batteries in various performances. The current common lithium iron phosphate battery does not have a memory effect like lead-acid batteries. After more than 1600 recharges, the battery storage capacity can reach 85%. Compared with lead-acid batteries, lithium batteries have the advantages of light weight, large capacity, and long life.

2. Lead-acid batteries.

The electrode is mainly composed of lead and oxide, and the electrolyte is a sulfuric acid solution. In the charged state, the important component of the positive electrode is lead dioxide, and the important component of the negative electrode is lead. In the discharge state, the main components of the positive and negative electrodes are lead sulfate. Lead-acid batteries have a memory effect, and the storage capacity will be lost if overlapped more than 500 times.

Therefore, many customers also highly approve of Baoding lithium battery solar street lights. This is why solar lamps with lithium batteries are becoming more and more popular.

3. Why choose solar lithium batteries more than lead-acid batteries?

Lithium battery is small in size, light in weight, saving time and effort

Now the world’s preferred solar street lights are generally integrated street lights. If lead-acid batteries are used, they should be buried underground around the light poles and placed in the buried box. If lithium batteries are used, they can be hung because of their lighter weight. Go to the back of the panel, saving time and effort.

Lithium batteries are less polluting than lead-acid batteries and are environmentally friendly

We all know that the service life of lead-acid batteries is relatively short. Although the price is cheap, it may be replaced once a year, which will greatly increase the pollution to the environment. Moreover, the pollution of lead-acid batteries is greater than that of lithium batteries. If they are replaced all the time, they will always cause damage to the environment. Lithium batteries are clean, while lead-acid batteries are contaminated with heavy metal lead.

Lithium battery is smarter

The current lithium battery has become more and more intelligent, and its functions are becoming more and more perfect. Today’s lithium batteries can adjust the battery usage time and so on according to the user’s battery needs. Many lithium batteries can be installed with a BMS management system, the status of the battery can be checked in real time on the mobile phone, and the current and voltage of the battery can be detected autonomously. If there is any abnormal situation, the BMS system can automatically adjust.

Lithium battery has longer life

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

Lithium battery is safer and has no memory effect

Lead-acid batteries are easy to enter water, while lithium batteries are not easy to enter water. Moreover, lead-acid batteries have memory. Charging has a memory effect when it is not fully discharged, which will affect the service life of the battery. Lithium batteries have no memory and can Recharge at any time. It is safer and more reassuring to use. Lithium iron phosphate has undergone strict safety tests and will not explode even in severe collisions.

△ High energy density of lithium battery

Lithium batteries have a high storage energy density, which has 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 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 reach 350~500℃, and it can be used in the environment of -20℃~60℃.

▽Price and warranty period

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 lithium battery is relatively expensive, the price is about 1,000 yuan, but there is a two-year warranty.

Fourth, generally speaking, the advantages of solar lithium battery street lights.

1. Adjustable flat support to maximize the collection of light.

2, green and environmental protection.

3. The lithium battery is easy to install, directly installed under the solar panel, small in size and light in weight, reducing construction costs.

4. Long service life, 3-5 times that of traditional lead-acid batteries.

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

6. ​​Good maintenance-free performance.

Summary: The above is about the advantages of solar street lamp lithium battery compared with lead-acid battery. Lithium battery is a controllable and pollution-free energy storage battery, which is more stable and safer than lead-acid battery. Lithium battery solar street lights are more popular with customers, and they also recognize Baoding lithium battery solar street lights. Lithium batteries for solar street lights have become a development trend, and more and more solar street lights will choose to use lithium batteries as energy storage devices in the future.
