Lithium battery solar street lights: Why do solar street lights use lithium battery for power storage?

2021-01-05

There is no doubt that it is better than lead-acid batteries in all aspects. The most common one is lithium iron phosphate batteries. This battery does not have a memory effect like lead-acid batteries. After more than 1,600 recharges, the storage capacity of the battery is still It can reach 85%. Compared with lead-acid batteries, lithium batteries have the advantages of lightness, large capacity and long service life.
Lithium batteries are actually lithium-ion batteries. The common ones are simply cobalt-lithium, manganese-lithium and iron-lithium. In the past, the safety problem of lithium batteries refers to cobalt-lithium, but after continuous technological progress, the current manganese-lithium and iron-lithium can fully guarantee Safety issues, otherwise, don`t most of the products that use lithium batteries such as power tools and IT products around us become time bombs? Especially iron-lithium batteries will be the most efficient batteries used in electric vehicles in the next few years, such as BYD. The iron batteries used in electric vehicles are actually lithium iron batteries.
The cycle life of lead-acid batteries is about 300 times, the cycle life of manganese-lithium batteries reaches 500-800 times, the cycle life of iron-lithium batteries reaches 2000 times, and Toshiba`s new Lithium Battery reaches more than 5000 times.
The charging time of lead-acid batteries is generally more than 6-8 hours. The lithium battery uses a special charger, and the charging time only needs 2-3 hours. Toshiba's new lithium battery can recover 90% of the power in a few minutes.
The most important cost issue is that the cost of lithium battery is actually not much more expensive than that of lead-acid. In the case of small energy storage batteries, lithium battery is more competitive than lead-acid. The reason why lithium battery is currently expensive is that its technology is still improving. The old production process is quickly eliminated. In order to recover costs in a short time, manufacturers must have a higher profit rate than other industries. When the technology is mature and the industrial scale is formed, lithium battery The price will definitely be cheaper than lead acid.
Of course, technology is constantly improving. The replacement of lead-acid in lithium batteries is not the direction of future batteries. Lithium batteries are not revolutionary technological progress. The scientific community is more inclined to the direction of fuel cells. In the foreseeable future, fuel cells may be The most ideal solution for human energy storage.
In general, the advantages of solar lithium battery street lights:
1. Adjustable Solar Panel bracket to maximize light collection;
2. Green and environmental protection;
3. The lithium battery is convenient to install directly under the solar panel, which is small in size and light in weight to reduce construction costs;
4. Long service life is 3-5 times that of traditional energy storage lead-acid batteries.

Lithium battery solar street lights should be widely used, such as lithium battery solar street lights, lithium battery solar high pole lights, lithium battery Solar Garden Lights, lithium battery solar antique garden lights, lithium battery solar LED lights, lithium battery solar stadium lights and so on. Baorun Lighting Group Co., Ltd. is a manufacturer of outdoor lighting products integrating design, R&D, production, sales, construction and installation services. It mainly produces various lithium-ion solar street lights, solar street lights, road lights, high pole lights, and landscape lights. , Courtyard lights, lawn lights, underground lights, scenic spot lighting, landscape lighting, building lighting engineering design and construction, etc.
