What material is the best cell phone battery?

There are two types of secondary batteries currently used in the market: nickel-metal hydride (Ni-MH) and lithium-ion (Li-ion). Lithium-ion batteries have been mass-produced liquid lithium-ion batteries (LiB) and polymer lithium-ion batteries (LiP). Therefore, in many cases, the battery marked with Li-ion must be a lithium-ion battery. But it is not necessarily a liquid lithium-ion battery, it may also be a polymer lithium-ion battery. Lithium-ion batteries are an improved product of lithium-ion batteries. Lithium-ion batteries have existed a long time ago, but lithium is a highly active metal. It is not safe to use. It often burns and bursts during charging. Later, there are improved lithium-ion batteries. The addition of ingredients (such as cobalt, manganese, etc.) that can inhibit the activity of lithium elements makes lithium batteries truly safe, efficient, and convenient, and the old lithium-ion batteries are basically eliminated. As for how to distinguish between them, it can be identified from the battery identification, lithium-ion batteries are Li, and lithium-ion batteries are Li-ion. Now, the so-called lithium-ion batteries used in notebooks and mobile phones are actually lithium-ion batteries. The new generation of polymer lithium-ion battery has a high degree of polymerization, so the shape can be thinner (the thinnest 0.5 mm), any area and any shape, which greatly improves the flexibility of battery shape design Therefore, it can be made into batteries of any shape and capacity according to product requirements. At the same time, the unit energy of polymer lithium-ion batteries is 50% higher than that of current general lithium-ion batteries, and its capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and environmental performance are greater than lithium-ion batteries. The increase in range. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete it.
