A metallic electrode comprises an electroactive material comprising zinc, aluminum, lithium, magnesium, silver, brass, copper, stainless steel, nickel, selenium, or any combination thereof, and an additive comprising a metal selected from the group consisting of bismuth, copper, indium, a salt thereof, an oxide thereof, and any combination thereof. The additive is plated in a layer on the electroactive material.

The application relates to the field of lithium ion battery technology and, more particularly, relates to a lithium-supplement layer and its negative electrode sheet, a lithium ion battery and a device. The lithium-supplement layer is formed by connecting a transition layer, an oxide layer and a surface layer in sequence, the surface layer contains an appropriate amount of an organic material and a filling substance, which can reduce a winding temperature of the negative electrode sheet, the oxide layer substance in the lithium-supplement layer is used to provide an additional lithium source, after injection, the lithium source can be continuously supplemented during the cycle process to improve the activity of a lithium layer, at the same time, the filling substance contained in the surface layer can effectively play a role of restraining the expansion of an active substance, and improve the battery cycle performance.

An anode for a zinc metal battery and a zinc metal battery using the same are provided. An anode for a zinc metal battery includes a zinc metal film and a protective layer formed on a surface of the zinc metal film, and the protective layer may be zinc phosphate. Since the protective layer coats the outermost surface of the zinc metal film, direct contact of the zinc metal film with an electrolyte can be prevented. Accordingly, zinc dendrites formed during plating/stripping of zinc ions during charging and discharging of the battery may grow uniformly, and thus, short circuit of the battery may be prevented.
