Technical problem of the present utility model is solved by following technical scheme:
A kind of coin shape battery, comprise housing, lid, electric core and electrolyte, be formed with host cavity between described lid and the housing, described electric core and electrolyte level are in described host cavity, also comprise sealing ring, described lid top is provided with boss, and described boss bottom is provided with the plane, and described sealing ring is positioned on the described plane.
Described coin shape battery also comprises first insulating barrier, and described first insulating barrier is between described housing sidewall and covered body wall.
The thickness of described first insulating barrier is 0.01mm-0.05mm.
Described first insulating barrier is a gummed paper.
Described coin shape battery also comprises second insulating barrier, and described second insulating barrier is positioned on the described housing bottom.
Described second insulating barrier is circle or annular.
The thickness of described second insulating barrier is 0.01mm-0.15mm.
Described coin shape battery also comprises the 3rd insulating barrier, and described the 3rd insulating barrier is positioned at below, described plane.
Described the 3rd insulating barrier is circle or annular.
The thickness of described the 3rd insulating barrier is 0.01mm-0.15mm.
The beneficial effect that the utility model is compared with the prior art is: the plane of the utility model bottom boss is as the support platform of sealing ring, and the cost that reduced simple in structure makes driving fit more convenient reliable, and security performance is better.The utility model has saved the flange of lid and the seal of parcel lid, and coin shape battery production technology of the present utility model is simpler, can more effectively utilize the space in coin shape battery container chamber, and volume and capacity ratio is higher.
