What are the benefits of
lithium batteries compared to lead-acid batteries for solar street lights?
With the continuous development of technology, the technology of lithium batteries is becoming more and more mature, with increasing capacity, longer lifespan, and wider range of applications. Nowadays, the use of lithium batteries has developed into the solar street light industry, replacing lead-acid and colloidal batteries. So, what are the benefits of lithium batteries for solar street lights compared to lead-acid batteries?
1. Lithium batteries are lightweight and easy to install:
The preferred choice for solar street lights worldwide is generally integrated street lights. If lead-acid battery packs are used, they need to be buried underground next to the lamp post and placed in a buried box. However, if lithium batteries are used, they can be attached to the back of the battery panel due to their lighter weight, saving time and effort.
2. Self discharge rate: The monthly self discharge of lithium batteries is less than 3%, while that of lead-acid batteries is 15-30%, with a significant difference.
3. Specific energy: The mass to volume ratio of lithium batteries is about 40% higher than that of lead-acid batteries.
4. Environmental friendliness: Lithium batteries have no pollution (not absolute), while lead-acid batteries are contaminated with heavy metal lead.
5. Safety: The safety of lithium batteries (lithium manganese oxide, lithium iron phosphate) varies depending on the material used. Although lead-acid battery technology is relatively mature, it pollutes the environment.
6. Electrical characteristics: Simply put, for batteries of the same capacity, under high current discharge, lithium batteries release about 30% more electricity than lead-acid batteries.
7. Service life: Currently, the commonly used lithium iron phosphate has a storage capacity of about 85% after 1500 charges, while lead-acid batteries have a storage capacity of about 500 charges.
The above is an introduction to the advantages of lithium batteries for solar street lights compared to lead-acid batteries.
Solar Street Light Battery belong to the dry battery nature and are a controllable and pollution-free energy storage type of battery, which is more stable and safer than lead-acid batteries.
