There are three types of solar batteries: lithium-ion batteries, gel batteries and lead-acid batteries. Among them, lithium-ion batteries are the most frequently used batteries for solar lamps. Lithium-ion batteries are gaining more and more attention in the solar manufacturing industry. So, what are the unique advantages of lithium battery solar street lights that are favored?

　　1. Lithium battery is a characteristic of battery. It is a kind of controllable, zero-pollution energy storage technology type rechargeable battery, which is more stable, safe and controllable than lead-acid battery.

　　2. Highly intelligent and convenient, efficient power distribution is more reasonable

　　Lithium battery solar street lights can perform intelligent lifting calculations according to the remaining capacity of the rechargeable battery, the night time of the solar light controller and the weather conditions, and effectively distribute the power consumption.

　　3, lithium battery has a long life,

　　Lithium battery solar street lights have a long service life, which is cost-effective compared to the service life of lead-acid batteries of two to three years. The main light source's service cycle is generally about h. The use of lithium power can match the polarity of the solar light system software, eliminating the need for frequent replacement of the solar battery, saving worry and effort.

　　4. Lithium battery solar street light is easy to install

　　Lithium-ion batteries do not need to be buried in the ground like colloidal batteries and lead-acid batteries. Lithium-ion batteries are usually placed under solar panels, and they can be plugged in directly, simplifying the installation procedure.

　　5. Lithium battery has fast charging speed and high discharge depth

　　With the same battery charging time, the lithium battery can charge faster and has a larger capacity, while the lithium battery solar street light has a higher charge and discharge depth. The same light, the lithium battery solar street light requires a small battery capacity.

　　Low-temperature lithium batteries are widely used due to their light weight, high energy density, long life and other advantages. Low-temperature lithium ion is a material and processing technology suitable for cold natural environments. Lithium batteries have the advantages of light weight, high energy density, and long life. Ultra-low temperature lithium batteries are made of materials and processing techniques, suitable for cold natural environments under zero conditions, and have excellent charging and discharging capabilities and working characteristics.

　　Low-temperature lithium batteries have the characteristics of low-temperature charge and discharge, minus 55 degrees discharge, light weight, high energy density, and long life. Low-temperature lithium batteries are made of materials and processing techniques, suitable for cold natural environments under zero conditions, and have excellent charging and discharging capabilities and working characteristics. Ultra-low temperature lithium ion batteries were prepared using vgcf and specific surface area (000500)/g as corrosion inhibitors and suitable cathode materials. The electrolysis of special lithium ion batteries with special corrosion inhibitors was introduced to ensure the ultra-low temperature charging and discharging effects of lithium ion batteries.

　　According to the natural environment of its application, it is divided into three series of products: civilian low-temperature rechargeable batteries, special low-temperature rechargeable batteries, and low-temperature rechargeable batteries:

　　A. Civilian low-temperature lithium battery: -20c battery charge and discharge account for 90% of the short-circuit capacity; -30c battery charge and discharge account for 85% of the short-circuit capacity;

　　B. The charge and discharge capacity of the special low-temperature lithium battery-40c battery is above 80%.

　　C. Extreme environment low temperature lithium battery: At -50℃, the charge and discharge capacity of the rechargeable battery is greater than 50%.

　　Equipped with switching power supply for troops, aviation, aerospace, submersible equipment, base scientific research, risk equipment power supply system, cold zone disaster relief, disaster prevention switching power supply, cold clothing, antifreeze shoes, switching power supply lights.
