How many types of batteries for solar street lighting system?
Corresponding to the above different types of solar led street light systems, most led solar street lamp manufacturers use the following 4 types of batteries.
1. Lead-Acid Battery
Lead-acid battery (VRLA) is a kind of battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. It is also called AGM Battery.
2. GEL Battery
GEL batteries belong to a development classification of lead-acid batteries. The method is to add a gelling agent to sulfuric acid to make the sulfuric acid electro-liquid into a colloidal state. It is equivalent to an upgraded version of lead-acid batteries. It is maintenance-free and solves the criticism of frequent maintenance of lead-acid batteries.
3. Ternary Lithium Battery
Ternary polymer lithium battery refers to a lithium battery using lithium nickel cobalt manganate (Li (NiCoMn) O2) or lithium nickel cobalt aluminate as the positive electrode material. The nominal voltage of a single ternary lithium battery is 3.7V. In solar-led street lamp systems, 3.7V battery systems are usually used.
4. Lithium Iron Phosphate Battery
