Classification and characteristics of lithium batteries

Classification of lithium batteries

1. According to different cathode materials, it can be divided into lithium ferrite battery, lithium cobalt battery, lithium manganese battery, lithium nickel battery, lithium ternary material battery, lithium iron phosphate battery

2. According to different electrolyte materials, it can be divided into liquid lithium battery and solid polymer lithium battery

In terms of packing, it can be divided into flexible packing, steel packing, aluminum packing and so on

4. In terms of use, it can be divided into power type lithium battery, consumption type lithium battery, energy storage type lithium battery, etc.

Lithium battery features advantages

1.The energy is higher.It has a high storage energy density, which has reached 200-300Wh/kg, which is about 6-7 times that of lead-acid batteries.

2.Long service life, the service life can reach more than 15 years, lithium iron phosphate as positive battery 1C (80%DOD) charge and discharge, can be used 6000 times record;

3.The rated voltage is high (the working voltage of the single unit is 3.7V or 3.2V), which is equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient to form the battery power group;Lithium-ion batteries can be used through a new type of lithium battery voltage regulator technology, the voltage up to 3.0V, suitable for small appliances.

4.It has a high power bearing capacity, in which the lithium ion battery of ferrous iron phosphate used in electric vehicles can reach the charge-discharge capacity of 15-30C, which is convenient for high strength start-up and acceleration;

5.The self-discharge rate is very low, which is one of the most prominent advantages of the battery, generally can do less than 1%/ month, less than 1/20 of the nickel hydride battery;

6.Light weight, the weight of the same volume is about 1/6-1/5 of lead-acid products;

7.High and low temperature adaptability is strong, can be used in -20℃–60℃ environment, after processing, can be used in -45℃ environment;

8.Green environmental protection, no matter the production, use and scrap, do not contain, do not produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.
