Tabletting and upper sheet metal, lower sheet metal, for pressure release piece between upper sheet metal and lower sheet metal, the middle part of the pressure release piece is recessed
It falls into, minimum point welds together with lower sheet metal, and lower sheet metal is opposite with inside battery (i.e. upper sheet metal is outermost);It is described
Current interruptive device connect with upper cover by four solder joints.
Wherein, respectively there is one section of reduced diameter at the both ends of the cylindrical shell and the groove that constitutes, the end of cylindrical shell
Mouth bore is less than the outer diameter of the cylindrical shell, and the part between groove and port is made to form flange;The upper cover and lower cover
It is packaged on the flange with the mode of gland.
Or, the both ends of the cylindrical shell respectively have one section to be provided with external screw thread, it is provided in the upper cover and lower cover
Internal screw thread, upper cover and lower cover are tightened by screw thread.
Cylindrical battery configuration of the invention can be prepared by the following method:
A kind of preparation method of the cylindrical battery configuration of non-metal shell, the cylindrical battery configuration include upper cover, lower cover
With the cylindrical shell of non-metallic material,
The cylindrical shell forms flange at both ends by integrally formed mode;With capping machine by the upper cover and under
The mode of lid gland is packaged on the flange.
Or: the cylindrical battery configuration includes the cylindrical shell of upper cover, lower cover and non-metallic material, described cylindrical outer
The both ends of shell respectively have one section to be provided with external screw thread,
Screw thread is processed in the upper cover and lower cover with idler wheel, upper cover and lower cover are tightened by screw thread, are made outside cylinder
The both ends compact package of shell.
By above-mentioned novel cylindrical battery configuration it is found that the present invention replaces original metal material using non-metallic material, at
Originally it is reduced, secondly because nonmetallic the light-weight of itself, intensity are high, designability is good, the use for meeting battery case is wanted
It asks and (for the corrosion resistance for improving glass, can also plate one layer of anti-corrosion coating in glass inner wall).Nonmetallic insulation performance, avoids
It is contacted using the tab or baffle of battery core caused by metal shell with shell, so that the battery short circuit caused, has given battery core more
Big design space.
Glass reinforced plastic is the mixture of glass fibre and resin, from a wealth of sources, and pressure resistance, corrosion resisting property are good.The present invention selects
Glass or glass-reinforced plastic material, machinability is strong, and light weight, intensity are high, and excellent corrosion resistance is cheap, is easily recycled, and can be used as
The alternative materials of battery case steel, aluminium.Due to the insulating properties of glass or glass reinforced plastic itself, tab or foil can completely avoid
It is rebuffed and causes the short circuit of battery, improve the design space of battery battery core.This non-metal shell uses the methods of rolling or gland
Nut cap sealing up and down is carried out, equipment is simple, and CT Cycle Time shortens, and nut cap is equipped with exhaust explosion-proof device, improves the peace of battery
Full performance.
