What is the reason for choosing solar lithium batteries more than lead-acid batteries?

1. There is no doubt that lithium batteries are better than lead-acid batteries in all aspects 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 recharges, the battery The storage capacity can still reach 85%. Compared with lead-acid batteries, lithium batteries have the advantages of lightness, large capacity, and long service life. 2. Lead-acid battery electrodes are mainly made of lead and oxide, and the electrolyte is sulfuric acid solution. In the charged state of the lead-acid battery, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead; in the state of being placed, the main component of the positive and negative electrodes are lead sulfate. Because of the memory effect of the lead-acid battery, the storage capacity of the battery will be greatly reduced when it is stacked more than 500 times. Therefore, many customers also highly approve of lithium battery solar street lights. This is the reason why solar lithium battery street lights are becoming more and more popular. 3. Why do I choose solar lithium batteries more than lead-acid batteries? Lithium batteries are small in size and light in weight, and save time and effort. Currently, the first choice for solar street lights in the world is generally integrated street lights. The surrounding underground is placed in the buried box, and if the lithium battery is used, with its lighter weight, it can be externally hung on the back of the battery panel, saving time and effort. Lithium batteries are less polluting than lead-acid batteries. We all know that lead-acid batteries have a shorter service life. Although they are cheap, they may have to be replaced once a year, which will greatly increase environmental pollution. In addition, lead-acid batteries are more polluting than lithium batteries. If they are replaced all the time, they will continue to cause harm to the environment. Lithium batteries are not polluted, while lead-acid batteries are polluted by heavy metal lead. Lithium batteries are smarter. Today's lithium batteries have become more and more intelligent, and their functions are getting better and better. The current lithium battery can be adjusted according to the user's demand for the battery, the length of use, and so on. Many lithium batteries can be equipped with a BMS management system, which can view the battery status on the mobile phone in real time, and can also independently test the current and voltage of the battery. If there is an abnormal situation, the BMS system can automatically adjust it. Lithium batteries have a longer service life. Lead-acid batteries have a relatively high annual loss. Lithium batteries have a service life of 35 years, and generally they 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 batteries are safer. Lead-acid batteries without memory effect are easy to enter water, and lithium batteries are not easy to enter water. And the lead-acid battery has memory, that is, the memory effect will appear when charging is not completely discharged, which will affect the service life of the battery. The lithium battery has no memory and can be charged at any time. This is safer and more reassuring to use. Lithium iron phosphate has undergone strict safety detection and will not explode even in severe collisions. Lithium batteries have high energy density. Lithium batteries have 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 lights are very resistant to high temperatures. Solar street lights are exposed to the sun every day, so they have 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℃. In terms of price and warranty period, the mainstream battery on the market is currently 12 volts. If it is replaced, the lead-acid battery is about 750 yuan and the warranty period is 3 years; the price of lithium batteries is relatively expensive, about 1,000 yuan, and the warranty period is three years. Fourth, in general, the advantages of solar lithium battery street lights. Adjustable solar panel brackets maximize light collection; green and environmentally friendly; lithium battery installation is convenient and straight installation under the solar panels, small size and light weight, reducing construction costs; long service life It is 3-5 times of the traditional energy storage lead-acid battery; it can be used in the environment of -20℃-60℃ for high and low temperature resistance, and the special craftsmanship of Seiko can be used in the environment of -45℃; the maintenance-free performance is good.
