Abstract

The utility model discloses an annular lithium thionyl chloride battery structure, which is as follows: an outer shell (1) is in an annular structure, a battery cover (2) is radially vertical to the outer shell (1), and is tangent with the excircle of the outer shell (1), the outer shell (1) is an annular part, and comprises an outer arc-shaped side plate, a panel and an inner cylindrical side plate which are connected by laser welding, the battery cover (2) is a part, and comprises a cover, a pole post and glass which are in 'metal-glass' sintering connection, and the battery cover (2) and the outer shell (1) are connected by laser welding. The battery structure is applicable to the occasions with annular installation space, and a battery has the capability of bearing impact overload.

Description

Annular lithium thionyl chloride cell structure

Technical field

The utility model relates to a kind of lithium thionyl chloride cell structure.

Background technology

Common low capacity lithium-thionyl chloride cell is cylindrical, and big capacity lithium-thionyl chloride cell is prismatic.Because some matching used special occasions are subjected to the restriction in space, these common planforms are difficult to meet the demands.Therefore the battery that needs a kind of special construction shape is to satisfy the demand of special occasions.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of annular lithium thionyl chloride cell structure is provided, to satisfy the specific (special) requirements of battery installing space, overcomes the deficiency that prior art exists.

In order to solve the problems of the technologies described above, the utility model is designed to loop configuration with the lithium-thionyl chloride cell.Concrete structure is: shell is a loop configuration, and battery cover is radially vertical with shell, and completes a business transaction mutually with the cylindrical of shell.

Above-described shell is an annular element, and it comprises external arc side plate, panel and interior cylinder side plate, adopts Laser Welding to connect between external arc side plate, panel and the interior cylinder side plate.

Battery cover is parts, and it comprises lid, pole and glass, and the connected mode between lid, pole and the glass is " metal-glass " sintering.

Adopt Laser Welding to be connected between battery cover and the shell.

The utility model is exclusively used in the occasion that the battery installing space is an annular.Since battery pole plates perpendicular to battery shaft to, the utlity model has high axial shock-resistant overload capacity.
