Safe transportation of lithium batteries
First, passengers or crew members for personal use of lithium or lithium-ion battery core or battery of portable electronic devices (watches, calculators, cameras, mobile phones, laptops, camcorders, etc.) should be carried on board as carry-on baggage, and lithium metal battery lithium content should not exceed 2 grams, The rated energy value of the lithium ion battery shall not exceed 100Wh (watt hours). More than 100Wh but not exceeding 160Wh, after approval by the airline can be installed in the delivery of baggage or hand luggage equipment. Lithium batteries exceeding 160Wh are strictly forbidden to carry.
Secondary batteries for portable electronic devices must be individually protected against short circuits (in the original retail packaging or otherwise insulated from the electrodes, such as tape on the exposed electrodes or in a separate plastic bag or protective box) and can only be carried in hand baggage, 100-160WH's standby lithium battery, approved by the airline, can carry only two.
III. Passengers and crew members carrying a lithium-ion battery-powered wheelchair or other similar means of transport and portable medical electronic devices containing lithium-metal or lithium-ion battery cores or batteries for medical purposes must be in accordance with the ICAO Technical rules on safe air transportation of dangerous goods Transport and packaging requirements are carried and approved by the airline.
IV. The calculation method of rated energy of lithium battery: the unit of rated energy is watt-hour WH, which is calculated by multiplying the rated capacity of the battery core or battery (in amperes-hour AH) to the nominal voltage (in volts v). Example: A mobile phone lithium battery rated capacity of 1650mAh, nominal voltage of 3.8V, the rated energy is 1.65x3.8=6.7Wh.
