How to change the lithium battery charging interface is as follows. On the back of the charging port, L represents the negative electrode, N represents the positive electrode, and the middle is generally empty. Most of these charging ports are made using plastic molding technology and are relatively inexpensive. Under normal circumstances, the stripped end of the wire is clamped and inserted into the hole corresponding to the charging port, which is easy to fix and solder and is relatively firm. After connecting the wire charging port, you need to remove the solder burrs under normal circumstances. It is recommended to use scissors to remove sharp parts. Make sure the tin is full and smooth after soldering. Prepare the corresponding heat shrink tubing and simply cover the box.

Main materials:
1. Carbon anode material: The anode materials actually used in lithium-ion batteries are mainly carbon materials, such as artificial graphite and natural graphite. , mesophase carbon microspheres, petroleum coke, carbon fiber, carbon pyrolytic resin, etc.
2. Tin-based negative electrode materials: Tin-based negative electrode materials can be divided into two types: tin oxide and tin-based composite oxide. Oxides refer to oxides of metallic tin in various valence states. There are no commercial products.
3. Nitride: It does notno commercial product exists.
4. Alloys: including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, and there are no commercial alloys. some products.
