In the element cycle table, lithium is the lightest and most negative metal, which is considered the best negative electrode material. Lithium metal is a material with metal lithium as negative. But in fact, there will also be li+migration during the charge and discharge process of lithium metal batteries. Therefore, in theory, it is a special lithium battery. However, in some technical documents, people generally believe that when lithium batteries are mentioned, they usually refer to lithium -free lithium; so -called lithium metal batteries are lithium as electrodes.

The difference between the two is obvious. Lithium ion is a +1 price Li+. There is no electronic loss during charging and discharging, and it does not change from Li+to single -quality lithium. In lithium ion batteries, with the charging and discharge of lithium ions, the charging and discharge of lithium ions The price has also changed.

When the lithium metal battery appeared for the first time in 1912, it was a battery, that is, a battery, because of its strong response ability, and was later replaced by lithium batteries. However, after more than 100 years of development, the current technology can be dissolved and precipitated in lithium. Therefore, in the current research report, most lithium metal is a secondary battery.
