Difference between lithium metal battery and lithium ion battery

Lithium metal batteries and lithium ion batteries are both lithium batteries, so what is the difference between them? will be described in detail below.

Lithium Ion Battery:

It is a secondary battery (rechargeable battery) that works mainly by moving lithium ions between the positive and negative electrodes. During charging and discharging, Li + is intercalated and de-intercalated between the two electrodes: when charging, Li + is de-intercalated from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode with plenty of lithium, it is opposite when discharging. Lithium-ion batteries actually use the concentration difference of lithium ions to store and discharge energy. There is no lithium metal in the batteries.

Lithium Metal Battery:

Lithium battery is a kind of high density energy storage battery by using lithium metal as electrode, which use lithium metal to generate electricity through lithium metal corrosion or oxidation.
