Lithium batteries exceeding these specifications can be sent by DHL, FEDEX, UPS international express or through logistics companies.
Express delivery companies do not accept lithium batteries, but logistics companies will. You can send it by post, but you have to package it yourself and the courier cannot open the box for inspection. It can be posted by logistics, preferably around 8 p.m.
Select Category: Digital Products, Shipping Method: Ground Shipping, usually you won't read it during this time. You can also send the entire vehicle, using shelves or auto parts, or bare bike frames. If the courier unpacks it and inspects it, it can be said to be sent back to the factory for repair.
Domestic SF Express, Yunda, ZTO, YTO, STO, etc. can release lithium batteries.
Because lithium batteries are not prohibited items, but lithium batteries are restricted items for air transportation, 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>Lithium-ion battery charging principle
The principleLithium-ion battery operating principle refers to its principle of charging and discharging. 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 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 toto the discharge capacity.
