The newly developed super lithium battery can be quickly charged in a short time. For example, the mobile phone is usually charged for 20 seconds. This type of battery may increase the future use of the battery, such as the use of electric vehicles, making it convenient to charge halfway, such as refueling.
Fold edit the main features of this paragraph
The main advantages of lithium battery: 1. Higher energy. Has a high storage energy density, has now reached 460-600Wh/kg, is about 6-7 times the lead-acid battery;
2. Long service life, life can reach more than 6 years, lithium iron phosphate is positive battery 1C (100% DOD) charge and discharge, there are 10,000 records that can be used;
3. High rated voltage (unit operating voltage is 3.7V or 3.2V), approximately equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, to facilitate the formation of battery power packs;
4. With high power endurance, lithium iron phosphate lithium-ion battery for electric vehicles can achieve 15-30C charge and discharge capability, facilitating high-speed start-up acceleration.
5. The self-discharge rate is very low, which is one of the most outstanding advantages of the battery. At present, it can generally be done below 1%/month, less than 1/20 of that of nickel-hydrogen batteries;
6. Light weight, weight of the same volume is about 1/6-1/5 of lead-acid products;
7. High and low temperature adaptability, can be used in -20 °C - -60 °C environment, after processing, can be used in -45 °C environment;
8. Environmental protection, regardless of production, use and scrap, does not contain any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.
9. Basically, production does not consume water, which is very favorable for water shortage in our country.
Specific energy refers to unit weight or unit volume of energy. The specific energy is expressed in Wh/kg or Wh/L. Wh is the unit of energy, W is watts, h is hour; kg is kilograms (weight units), L is liter (volume units).
