Characteristics and advantages of lithium battery

Advantage
1. The energy is relatively high. It has a high storage energy density, reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;
2. Long service life, with a service life of over 6 years. The battery with lithium ferrous phosphate as the positive electrode, 1C (100% DOD), has a record of being able to be used for 10000 times;
3. The rated voltage is high (the single working voltage is 3.7V or 3.2V), which is approximately equal to the series voltage of three nickel cadmium or nickel hydrogen rechargeable batteries, facilitating the formation of a battery power pack; Lithium batteries can be adjusted to 3.0V through a new type of lithium battery voltage regulator technology to suit the use of small appliances.
4. It has high power withstand capacity, among which the lithium iron phosphate lithium ion battery for electric vehicles can reach a charging and discharging capacity of 15-30C, facilitating high intensity startup acceleration;
5. The self discharge rate is very low, which is one of the most prominent advantages of this battery. Generally, it can achieve less than 1% per month, less than 1/20 of the nickel hydrogen battery;
6. Lightweight, with a weight of about 1/6-1/5 of that of lead acid products under the same volume;
7. Strong adaptability to high and low temperatures, which can be used in environments ranging from - 20 ℃ to 60 ℃. After technological treatment, it can be used in environments ranging from - 45 ℃;
8. Green and environmentally friendly, regardless of production, use, and scrap, it does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium.
9. Production basically does not consume water, which is very beneficial for China, which is short of water.
Specific energy refers to energy per unit weight or volume. Specific energy is expressed in Wh/kg or Wh/L. Wh is the unit of energy, W is the watt, and h is the hour; Kg is the kilogram (unit of weight), and L is the liter (unit of volume).
