Preferably, some second blind holes are also distributed with on the surface of described outer step.
Preferably, described some second blind holes become round to be evenly distributed on the close inner edge place on described outer step surface.
Preferably, it is characterized in that, described lithium battery is rectangle or circle.
Correspondingly, the invention also discloses a kind of large-capacity power lithium battery, include battery body and electrode terminal, this electrode terminal is drawn from described battery body sealing by a hush panel, described hush panel includes a metal substrate be connected with described electrode terminal sealed insulation, this metal substrate is provided with pass through aperture, the inner surface and outer surface of described metal substrate are respectively arranged with interior step and outer step around described through hole, focus on, at least have some first blind holes in the surface distributed of described interior step.
Preferably, described some first blind holes become round to be evenly distributed on the close inner edge place of described interior ledge surface.
Preferably, some second blind holes are also distributed with on the surface of described outer step.
Preferably, described some second blind holes become round to be evenly distributed on the close inner edge place on described outer step surface.
Preferably, described lithium battery is rectangle or circle.
The invention has the beneficial effects as follows:
Embodiments of the invention by arranging some blind holes on the metal substrate step of lithium battery seal plate, two inside and outside circle blind holes, round is become to be uniformly distributed in ledge surface, when riveting, colloid can be stoped to flow to surrounding, ensure that the decrement of fluid sealant, thus reach good sealing.The large-capacity power lithium battery of 50-200Ah can be adapted to completely.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
