In life, we will use lithium batteries every day, such as mobile phones, laptops, 12V electric fish lithium batteries, etc., they are all lithium batteries. There is a lithium component content in the lithium battery, then how is this lithium content calculated? First, I believe that many people don't know that the Civil Aviation Authority has a regulation of lithium battery transportation, which is the provisions in the "Lithium Battery Transportation Specification"; 1, lithium battery or spare battery in the equipment as luggage transportation, lithium Metal or lithium alloy battery lithium content does not exceed 2 grams.
2, the amount of lithium-ion battery should not exceed 100 wh (electricity, and current, voltage, time proportional). 3. For large lithium-ion batteries that are more than 100Wh less than 160Wh, it is necessary to carry it with you after approved, but the number of carry must not exceed two.
4, the equipment containing lithium batteries can be placed in checked baggage or hand, and the spare lithium battery can only be placed in the portable baggage. Second, 12V lithium battery lithium content calculation method: If there is a current (MAH) on the lithium battery, the amount of lithium content of the battery can be obtained by using the current to remove at 1000 by 0.3.
For example, the battery current is 5000mAh, then the content of lithium is 5000mAh ¡Â 1000x0.3 = 1.5 grams, and the lithium content is less than 2 grams, which is fully compliant with safety standards.
Third, rated energy calculation method: 1. If the nominal voltage (V) and nominal capacity (AH) of the battery can be calculated by calculation, the formula is: wh y = vxah, such as a 12V20AH lithium battery, The rated energy is 12 ¡Á 20 = 240; in general, nominal voltages and nominal capacity are marked on the battery. 2.
If there is only MAH (mA when there is only MAH (mA) on the 12V lithium battery, it can be divided by 1000 to obtain ampere hours (AH). For example, the lithium battery nominal voltage is 4.2V, the nominal capacity is 3000mAh, the rated energy is: 3000mAh ¡Â 1000 = 3ah3.
7V ¡Á 3ah = 11.
