Advantages

1. High energy. Has a high storage energy density, has reached 460-600Wh/kg, is about 6-7 times that of lead-acid batteries;

2. long service life, service life can reach more than 6 years, lithium iron phosphate as the positive electrode of the battery 1C (100% DOD) charge and discharge, there can be used 10,000 times the record;

3. high rated voltage (single working voltage of 3.7V or 3.2V), approximately equal to the series voltage of 3 NiCd or NiMH rechargeable batteries, easy to form a battery power pack; lithium batteries can be adjusted to 3.0V by a new lithium battery regulator technology, to suit the use of small appliances.

4. with high power tolerance, of which lithium iron phosphate lithium ion batteries for electric vehicles can reach 15-30C charge and discharge capacity, facilitating high-intensity start-up acceleration;

5. low self-discharge rate, which is one of the most outstanding superiority of this battery, generally can achieve less than 1%/month, less than 1/20 of NiMH batteries;

6. light weight, about 1/6-1/5 of the weight of lead-acid products in the same volume

7. high and low temperature adaptability, can be used in -20℃-60℃ environment, after process treatment, can be used in -45℃ environment;

8. Green and environmentally friendly, regardless of production, use and end-of-life, it does not contain, nor does it 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 to our country where water is scarce.

Specific energy refers to the energy per unit of weight or volume. Specific energy is expressed in Wh/kg or Wh/L. Wh is the unit of energy, W is watt and h is hour; kg is kilogram (unit of weight) and L is litre (unit of volume).

Disadvantages

1. Lithium primary batteries all have poor safety and are at risk of explosion.

2. Li-ion batteries of lithium cobalt acid batteries cannot be discharged at high currents, are expensive and have poor safety.

3. Lithium-ion batteries require protection circuits to prevent the battery from being overcharged and overdischarged.

4. High production requirements and high costs.

5. There are restrictions on the conditions of use and the danger of high and low temperature use is high.
