Abstract
The battery casing for packing secondary battery includes upper casing and lower casing, and features that the upper casing is fixed to the lower casing and forms the cuboid space for packing electric core, the upper casing consists of the upper layer and two sides of the cuboid, the lower casing consists of the lower layer and two sides of the cuboid, and one side has liquid injecting hole and electrode leading-out end. The technical effects of the utility model are that: the battery cell is connected with the lower shell, and the upper shell and the lower shell form a closed packaging space; the battery shell has the advantages that the mode that the battery core is placed into the shell is changed, friction generated by contact between the battery core and the shell wall is reduced, the battery core can be well protected, short circuit of the battery is effectively avoided, explosion is prevented, and the safety performance of the battery is improved.
Description
Technical field
The utility model relates to a kind of battery container, relates in particular to a kind of battery container that encapsulates secondary cell.
Background technology
Lithium rechargeable battery because have the operating voltage height, advantages such as specific capacity is big, charging rate is fast, good cycle, volume are little, light weight, in mobile communication, notebook computer, electric tool, the purposes in fields such as power vehicle is increasingly extensive, the also constantly expansion of production capacity in China.
Lithium rechargeable battery need be encapsulated in electric core in the housing in the process of producing, and housing plays a part fixing electric core position and the electric core safety of protection.Usually the housing that adopts is the opening cuboid and the cover plate combination of five connections at present, promptly by the opening surface of cuboid electric core is gone into shell, covers cover plate then and encapsulates, being made in electric core like this goes in the process of shell, shell wall scratches electric core easily, causes the short circuit of electric in-core portion, even blasts.
Summary of the invention
The purpose of this utility model has been to provide a kind of battery container that encapsulates secondary cell, and this battery container can not scratch electric core, has slowed down electric core and has contacted the friction that produces with shell wall, can play good protection to electric core.
The utility model is achieved like this, it comprises upper casing and lower casing, it is characterized in that the fixedly connected lower casing of upper casing is formed at the cuboid space of the electric core of encapsulation, upper casing is made of the last aspect and the two sides of cuboid, lower casing is made of the subsurface and other two sides of cuboid, wherein is distributed with liquid injection hole and electrode leads to client on the side.
The material of upper casing described in the utility model and lower casing is stainless steel, aluminium, nickel or copper.
Described upper casing of the present utility model is Laser Welding or electric resistance welding with the mode of fixedlying connected of lower casing.
The coverboard thickness of described upper casing of the present utility model and lower casing is 0.1-5.0mm.
Technique effect of the present utility model is: electric core is connected with lower casing earlier, and described upper casing and lower casing constitute airtight encapsulated space; Battery container has slowed down electric core and has contacted the friction that produces with shell wall owing to changed the mode that electric core is gone into shell, can play good protection to electric core, has effectively avoided the short circuit of battery, has prevented the generation of blast, has improved the security performance of battery.
