Analysis of the advantages of Solar Street Light Battery packs:
Energy density: Solar Street Light Batterys are smaller and lighter than lead-acid, nickel-cadmium, and nickel-metal hydride batteries.
Small size and light weight. The volume of the Solar Street Light Battery is 1/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.
Long service life: The cycle life of Solar Street Light Batterys is 1200 to 2000 times, but that of traditional lead-acid batteries is only 500 to 900 times.
Good high temperature performance: the thermal peak of Solar Street Light Battery can reach 350℃-500℃, while the lead-acid battery is only around 200℃.
High rate discharge: The discharge curve of Solar Street Light Battery, even at 5C discharge rate, the discharge rate can still reach 90%.
Fast charging: It can quickly charge and discharge with a high current of 2C. The battery can be fully charged within 40 minutes at 1.5C under a special charger, and the starting current can reach 2C, but lead-acid batteries do not have this performance now.
Safety and environmental protection: The Solar Street Light Battery pack has undergone strict safety tests and will not explode. Lithium-ion battery is a green battery.
No memory effect: There is no such phenomenon in the Solar Street Light Battery pack. No matter what the state of the battery is, it can be used at any time, and it is not necessary to discharge it completely before charging.
The selection of cathode materials for Solar Street Light Batterys is mainly based on the following factors:
1) It has a high redox reaction potential, so that the lithium-ion battery can reach a high output voltage;
2) The high content of lithium element and the high packing density of the material make the lithium-ion battery have a high energy density;
3) The structural stability during the chemical reaction process is better, so that the lithium-ion battery has a long cycle life;
4) The conductivity should be high, so that the lithium-ion battery has good charge and discharge rate performance;
5) The chemical stability and thermal stability are better, and it is not easy to decompose and generate heat, which makes the lithium-ion battery have good safety;
