Main advantages of lithium batteries
1. Main advantages of lithium batteries: Energy is relatively high. It has reached 460-600Wh / kg with high energy storage density;
2. Long service life and can last more than 6 years. Lithium iron phosphate is a 1C (100% DOD) positive battery charge and discharge and can be used 10,000 times.
3. Rated voltage is high (single operating voltage is 3.7V or 3.2V); this is equal to the series voltage of three nickel-cadmium or nickel-hydrogen rechargeable batteries suitable for forming a battery power pack;
4. Lithium iron phosphate lithium ion battery for electric vehicles with high power carrying capacity, can reach 15-30C charge and discharge capacity, which is suitable for high intensity start acceleration;
5. The self-discharge rate is very low, which is one of the best advantages of the battery. Presently, usually 1% / month or less may be below the 1/20 nickel-hydrogen cell;
6. The light weight of the same volume is about 1/6-1 / 5 of the lead acid product;
7. High temperature and low adaptability, can be used in the -20 ° C-60 ° C environment, can be used in -45 ° C environment after treatment;
8. Green does not contain toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium, regardless of whether they are produced, used or scrapped.
9. Production does not consume water, which is very beneficial for those who do not receive water from China.
Specific energy means energy per unit weight or unit volume. The specific energy is expressed in Wh / kg or Wh / L. What is the energy unit, W watt, hour is hour; kg is the kilogram (weight unit) and L is the liter (volume unit).
