Lithium-ion batteries are less polluting than lead-acid batteries and are environmentally friendly.
We all know that the service life of lead-acid batteries is relatively short. Although it is cheap, it may be changed once a year, which will greatly increase the pollution to the environment. And the lead-acid battery itself is more polluted than the lithium-ion battery. If it has been replaced, it will always cause harm to the environment. Lithium-ion batteries are not contaminated, while lead-acid batteries are contaminated with the heavy metal lead.
Today's lithium-ion batteries are getting smarter and better. Today's lithium-ion batteries can be adjusted according to the user's battery needs, duration, and so on. Many lithium-ion batteries can be installed with a BMS management system, which can check the status of the battery on the mobile phone in real time, and can also detect the current and voltage of the battery. If there is an abnormal situation, the BMS system can automatically adjust.
The annual loss of lead-acid batteries is relatively high, often a year or two to replace once. Lithium-ion batteries have a 35-year lifespan and are typically guaranteed for three years. Lead-acid batteries have a cycle life of about 300 cycles. And iron phosphate lithium ion battery, 3C cycle life reached more than 800 times.
Lithium-ion batteries are safer and have no memory effect.
Lead-acid batteries are susceptible to water, and lithium-ion batteries are susceptible to water. And lead-acid battery is with memory, is not fully discharged when charging will appear memory effect, will affect the service life of the battery. Lithium-ion batteries, on the other hand, have no memory and can be recharged at any time. It's safer and more reassuring to use. Lithium iron phosphate has undergone rigorous safety tests and will not explode even in a violent collision.
Lithium-ion batteries have a high storage energy density, which has now reached 460-600Wh/kg, about 6-7 times that of lead-acid batteries. This will better store energy for solar street lights.
Solar street lamps are exposed to the sun every day, so they have higher requirements for the temperature environment. The peak heat of iron phosphate lithium ion battery can be 350~500℃, and can be used in an environment of -20℃--60℃.
