Abstract

The utility model discloses a negative sheet of a metal lithium primary battery and relates to a structure of a battery, in particular to the structure of the metal lithium primary battery. Strip-shaped metal is arranged in a sheet-like main body; a negative lug is connected with the sheet-like main body and the strip-shaped metal; the sheet-like main body is a metal lithium foil or a lithium alloy foil; the strip-shaped metal is a metal screen or a metal foil; and the negative lug is formed by adhering a hot melt adhesive to a pure nickel strip. The negative sheet of the metal lithium primary battery reduces the internal resistance of the battery, improves the utilization ratio of a negative electrode, is good in conductivity and safety performance, has a high and stable battery discharge platform, and can effectively avoid generation of dendritic crystal and death of lithium and effectively avoid short circuit and the like.

Description

Lithium metal primary cell negative plate
Technical field:
The utility model relates to battery structure, especially lithium metal primary cell structure.
Background technology:
Existing lithium primary battery metallic lithium foil negative plate on the market, utilance is not high; With the lithium metal primary cell of metal lithium bands as negative plate, negative pole and collector contact resistance are big, and the discharge performance instability can not satisfy the cell discharge performance requirement well; Because electric conductivity is not ideal enough, poor safety performance more easily takes place in the phenomenon that produces dendrite and dead lithium.
Summary of the invention:
The purpose of this utility model is: the lithium metal primary cell negative plate that a kind of high usage, satisfactory electrical conductivity are provided.
It comprises flake main body; Strip metal is set in flake main body; Negative lug is set connects flake main body and strip metal.
Described flake main body is metallic lithium foil or lithium-aluminium alloy paper tinsel.
Described strip metal is wire netting or metal forming.
Described negative lug is an attached PUR on the pure nickel nickel bar.
The utility model has reduced the internal resistance of battery, has improved the utilance of negative pole, and conductivity and safety can be good, and the battery discharge platform is high and stablize; Can effectively avoid producing dendrite and dead lithium, situation such as effectively avoid being short-circuited takes place.
