Metal lithium battery

A metal lithium battery comprises a battery cell and a negative pole lug, the battery cell comprises a negative pole piece monomer, a positive pole piece monomer and a diaphragm piece, the negative pole piece monomer comprises a lithium pole piece and a current collector electrically connected with the lithium pole piece, the current collector comprises a plurality of current collectors, and eachcurrent collector is electrically connected with the lithium pole piece. Therefore, the accumulated area of each current collector can be further smaller than the area of the traditional monolithic current collector, and the accumulated weight of each current collector is smaller than the weight of the traditional monolithic current collector, so that the utilization rate of the negative active material can be further improved, and the battery capacity can be further improved. 一种金属锂电池，金属锂电池包括电芯及负极极耳，所述电芯包括负极片单体、正极片单体及隔膜片，所述负极片单体包括锂极片及与所述锂极片电连接的集流件，所述集流件包括多个集流体，各所述集流体分别与所述锂极片电连接。能够进一步使得各集流体累加的面积比传统整片式集流件的面积更小，以及各集流体累加的
