How to Choose The Lithium Battery
As we all know, since introduced in 1990, lithium battery has been rapidly developed and widely used for civilian use for its outstanding performance. Due to the incomparable advantages, the Lithium battery quickly occupied in many fields, such as lighting tools, electric toys, digital camera, and so on, and it has been used for military purposes in more and more countries. But how many people really know the features of the lithium battery, the advantage and disadvantage? Well, let’s do a summary today.
Main advantages of lithium battery:
1. Energy ratio is relatively high. With the high storage energy density, it has now reached 460-600Wh/kg, which is about 6-7 times that of the lead-acid batteries;
2. Long service life. The service life is up to more than 6 years, lithium iron phosphate cathode battery 1C (100%DOD), charge and discharge, can be used more than 10,000 times;
3. Rated voltage higher (working voltage of single cell 3.7V or 3.2V), approximately equal to 3 series voltage NI-CD or Ni-MH rechargeable battery, it is easy to make up battery power group;
4. High power capacities, with lithium iron phosphate lithium-ion batteries for electric vehicles can reach the 15-30C ability to charge and discharge, easy to start accelerating with high strength;
5. A low self-discharge rate, this is one of the most prominent advantage of the lithium battery, usually can be under 1%/months, less than 1/20 of nickel-metal hydride batteries;
6. Light weight, the same size weight is about lead acid products 1 / 5-6;
7. High and low temperature adaptability, can be used under-20 ℃-60 ℃ environmental, after processing ,it can be used at-45 degrees centigrade environment;
8. Green environmental protection, from production, use to discard, does not contain, nor produce any poisonous and harmful heavy metals such as lead, mercury, cadmium and material.
9. Production largely consuming water, for water shortage in China, which is very favorable.
Disadvantages of lithium battery:
1 Primary lithium battery has poor safety, with the risk of explosion, should be used carefully;
2. Lithium cobalt oxide for lithium ion batteries cannot be large current discharge, a little less secure.
3 Lithium batteries are required to protect the circuit, preventing the battery from being overcharge or over discharge.
4. High production requirements, high cost. That’s the reason why the price of the lithium battery like the XPS m1210 battery is usually higher than the other kinds of batteries.
