Which courier can I send lithium batteries to?
SF Express, etc.
Express delivery companies such as SF Express, Yunda, ZTO, YTO, STO, etc. can carry lithium batteries. It should be noted that lithium batteries are air transport restricted items, so they cannot be transported by air and cannot be transported by air.can only be transported by land.
How to express lithium batteries
Domestic SF Express, Yunda, ZTO, YTO, STO, etc. can all deliver lithium batteries.
Because lithium batteries are not prohibited items, but lithium batteries are restricted items for air transportation, so they cannot be transported by aircraft and cannot be transported only by land.
Lithium batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. This battery is therefore also called a lithium metal battery. Unlike other batteries, lithium batteries have the characteristics of high charge density, long life and high unit cost. According to structureDifferent designs and materials of electrode, lithium batteries can produce voltages from 1.5 V (equivalent to zinc-carbon or alkaline batteries) to 3.7 V.
Lithium-ion battery charging principle
The working principle of the lithium-ion battery refers to its charging and discharging principle. When the battery is charged, lithium ions are generated on the positive electrode of the battery and the generated lithium ions move to the negative electrode via the electrolyte. The carbon used as a negative electrode has a layered structure with numerous micropores. The lithium ions that reach the negative electrode are integrated into the micropores of the carbon layer. The more lithium ions, the higher the charging capacity.
Similarly, when the battery is discharged (that is, the process when we use the battery), the lithium ions embedded in the carbon layer of the negative electrode are released and returntowards the positive electrode. The more lithium ions that return to the positive electrode, the higher the discharge capacity. What we usually call battery capacity refers to the discharge capacity.
Lithium batteries can be sent by express delivery, but certain regulations and requirements must be met. Lithium batteries cannot be sent by ordinary express delivery because lithium batteries are corrosive and are prohibited items. However, you can choose specific logistics companies, such as postal companies or some international express companies (such as DHL, Fedex, UPS and TNT). These companies can usually provide specialized transportation services. When mailed, lithium batteries must be properly packaged and marked in accordance with the mailing company's regulations.management to guarantee safe transport. Additionally, because lithium batteries are aviation regulated items, they cannot be transported by air and can only be transported by ground.
