Description
Technical field
The utility model relates to a kind of battery cover board, is specifically related to a kind of cover plates of lithium ion power battery.
Background technology
But lithium-ion-power cell has the large high current charge-discharge of energy density, characteristics that environmental pollution is little just are widely used, but because the positive and negative pole of battery is respectively rivet usually connects, causes the electric current contact interface more; Battery electrode column with external circuit tight process in, be easy to rotate pole, also driven the sealing gasket below it simultaneously, this has not only destroyed the sealing property of battery, and short circuit hidden danger occurred; Usually the pole of electrokinetic cell is externally threaded, has taken many useful spaces of electrical equipment, and be used for external circuit also can jack panel appear along with the vibrations of battery becoming flexible phenomenon; The cell cover contact area is little, heat production is many, be difficult for connecing large electric current drawback this affect on the one hand voltage platform, also make on the other hand battery exist the problems such as potential safety hazard.
Therefore, in this kind situation, need to provide a kind of reasonable in design, simple in structure, practical lithium-ion power battery cover to solve problem above-mentioned, this also is the problem that the lithium ion battery research staff needs solution badly.
The utility model content
The utility model exists short circuit hidden danger, the easy problem such as the poor drawback that is difficult for connecing large electric current of loosening phenomenon, heat conductivility and potential safety hazard in order to solve existing battery cover board, thereby has proposed a kind of cover plates of lithium ion power battery.
A kind of cover plates of lithium ion power battery, it comprises cell connector, the first electrode column, the first electrode pressing plate and the first electrode connecting piece, described cell connector is axially symmetric structure;
One end of described the first electrode column is fixed on the first electrode connecting piece, and the other end of this first electrode column passes cell connector,
The first electrode pressing plate is enclosed within the other end of the first electrode column, and cell connector, the first electrode pressing plate are fixedly connected with by electric welding or riveting method with the first electrode connecting piece.
The utility model has been avoided short circuit hidden danger, has realized that external circuitry is connected with battery closely, and power battery electrode spare is large with the cell cover contact area, heat production is few, easily connect the purpose of large electric current, and has reached the effect of the useful space of having dwindled power supply.
