The calculation method of 12 v lithium battery lithium content

We use lithium batteries every day, such as mobile phones, laptops, 12v lithium battery electric fish, and so on. Lithium battery contains lithium components, so how to calculate the lithium content?

First, I believe many people don’t know that the civilspecial administration of China has a regulation on lithium battery transport, that is, the regulations mentioned in the regulations on lithium battery air transport;

1, when the lithium battery or spare battery in the equipment is transported as luggage, the lithium content of lithium metal or lithium alloy battery does not exceed 2 grams.

2, Lithium ion battery rated energy should not exceed 100Wh (electric quantity, proportional to current, voltage and time)

3, for large lithium-ion batteries with rated energy greater than 100Wh and less than 160Wh, approval from the airline operator is required before carrying them with you, but the carrying amount shall not exceed two.

4, Equipment containing lithium batteries can be placed in checked luggage or hand luggage, spare lithium batteries can only be placed in hand luggage.

Second, Calculation method for lithium content of 12v lithium battery:

If you have any current lithium battery marked (MAH), using the current divided by 1000 and then multiplied by 0.3, will be able to get the grams of the content of lithium battery. For example: the battery current is 5000 MAH, the lithium content is 5000 MAH, present 1000 x0. 3 = 1.5 grams, less than 2 grams of lithium content, full compliance with safety standards.

Third, the rated power calculation method:

1, if the nominal voltage (V) and the nominal capacity (Ah) of the battery are known, the rated energy can be calculated. The formula is: WH=V*Ah. For example, for a 12V20AH lithium battery, the rated energy is 12 * 20=240. In general, both the nominal voltage and the nominal capacity are marked on the battery.

2, if the 12V lithium batteries show only a MAH, that number can be divided by 1000 ampere hour (Ah).Nominal voltage of 4.2 V lithium-ion batteries, for example, nominal capacity is 3000 MAH, the rated power is:

3000mAh÷1000=3Ah3.7V×3Ah=11.1Wh
