Which logistics company can send lithium batteries?

Introduction It doesn't matter which logistics company can send lithium batteries. National SF Express, Yunda, ZTO, YTO, STO, etc. can be mailed because lithium batteries are not prohibited items, but lithium batteries are restricted by aviation.

Which logistics company can send lithium batteries?

Both are fine.

National SF Express, Yunda, ZTO, YTO, STO, etc. can be sent by post because lithium batteries are not prohibited items, but lithium batteries are restricted items for air transportation, so they cannot be transported by air, only ground transportation can be used . The four major international express delivery companies, DHL, FEDEX, UPS and TNT, can all send batteries by courier, but they differ in the categories of batteries they accept.

1. DHL: Lithium-ion cells, batteries, battery packs, laptop batteries, camera batteries, mobile phone batteries, etc.

2. FEDEX: lithium ion cells, batteries, battery packs, lithium metal batteries, overweight batteries, overweight batteries, imitation batteries, dry batteries and mobile power supplies.

3.TNT: lithium ion cells, batteries, battery packs, lithium metal batteries, overweight batteries, overweight batteries, imitation batteries, dry batteries and mobile power supplies.

4. UPS: Lithium-ion cells, batteries, battery packs, dry cells and imitation batteries.

Structure of lithium battery

Lithium batteries generally have two shapes: cylindrical and square. The internal structure of the battery is a spiral winding structure, with very thin, highly permeable polyethylene film insulating material separated between the positive and negative electrodes. The positive electrode includes a current collector composed of lithium cobalt oxide (or lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.) and a foil 'aluminum.

The negative electrode consists of a current collector made of graphitized carbon materialand a sheet of copper. The battery is filled with an organic electrolyte solution. In addition, a safety valve and PTC element (used in some cylindrical types) are installed to protect the battery from damage caused by abnormal conditions and output short circuits.

The voltage of a single lithium battery is 3.7V (the positive electrode of lithium iron phosphate is 3.2V), and the capacity of the battery cannot be infinite. Therefore, single lithium batteries are often connected in series or parallel. .To meet the requirements of different occasions.

What kind of courier can send lithium batteries?

Domestic SF Express, Yunda, ZTO, YTO, STO, etc. can all send lithium batteries.

Because lithium batteries are not prohibited items, but lithium batteries are restricted items for transportationort, so they cannot be transported by plane and can only be transported 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. Depending on the structural design and electrode materials, lithium batteries can produce voltages ranging from 1.5 V (equivalent to zinc-carbon or alkaline batteries) to 3.7 V.

< strong>Charging principle of lithium-ion battery

The working principle of lithium-ion battery refers to its charging and discharging principle. When a battery is charged, there islithium on the positive electrode of the battery Ions are generated, and the generated lithium ions move to the negative electrode through 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 return towards 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.

What type of logistics can send lithium batteries

SF Express, Yunda, ZTO, YTO, STO, etc. Because lithium batteries are not prohibited postal items, but because lithium batteries are air transportation restricted items, they cannot be transported by air and can only be transported by air earthly. Additionally, lithium batteries must be installed in equipment with protective devices, and each package must do so. contain The quantity and capacity of lithium batteries are limited, so domestic express companies such as SF Express, Yunda, ZTO, YTO, STO, etc. can send lithium batteries.

SF Express, YTO, Yunda, STO, ZTO, etc. can send lithium batteries.
