Graphene battery

Abstract

The invention belongs to the technical field of batteries, and particularly relates to a graphene battery. The graphene battery comprises an outer shell; a top cover is arranged in an upper port of the outer shell; the top cover is provided with an electrode column, and the bottom end of the electrode column is connected with an electrode of an internal graphene conducting layer; a stepped threaded hole is formed in the top end of the electrode column, and an electric connecting piece is attached to the upper end of the electrode column; a conductive wire is installed on the side face of the electric connecting piece, and elastic bent pieces are evenly arranged on the inner ring wall of the electric connecting piece. A T-shaped pressing sleeve is inserted into the inner ring of the electric connecting piece, and the outer ring wall of the T-shaped pressing sleeve is in extrusion fit contact with the elastic bent pieces; the T-shaped pressing sleeve is inserted into the stepped threadedhole, and a hexagon socket screw is inserted into the T-shaped pressing sleeve; the hexagon socket screw is in threaded connection with a bottom end hole of the stepped threaded hole; and the phenomenon that the electric connecting piece is separated from the electrode column due to axial rotation of the electric connecting piece caused by vibration of the conductive wire, and then the stable connection between the conductive wire and the electrode column is affected is prevented.

Problems solved by technology

[0004] The graphene battery designed above can reduce the contact resistance and enhance the conductivity by arranging the graphene in a multi-layer hole-like stack; but when the existing electric vehicle rides on a rough road, the graphene battery will vibrate and lose As a result, the conductive wire will swing, and then the conductive wire will drive the electrical connecting piece to rotate axially on the electrode column, and because the existing electrical connecting piece is only connected to the electrode column through bolts and threads, when the electric connecting piece that rotates axially for a long time The rotational friction between the connecting piece and the bolt will cause the bolt to detach from the electrode column, which will affect the stable connection between the conductive wire and the electrode column
