Abstract
A power battery outer casing comprises a casing and a cover plate, and is characterized in that the cover plate is connected with the casing, the casing is a groove in a symmetric stepped shape, the casing includes three steps, the first step is a casing bottom plate for containing an electrode, a second step is an electrode tab position respectively for fixing an anode tab and a cathode tab of the electrode, the third step is a cover plate position, the length and the width of the cover plate are no smaller than those of the casing, and a liquid injection hole is arranged on the casing. The power battery outer casing has the advantages that the outer casing adopts the stepped groove casing, leads the outer casing of a power battery to be more rationalized, is simple and convenient in assembly and operation, is not easy to damage an electrode, has reduced requirement on a welding clamp of the cover plate and the casing, and saves production cost. Besides, an electrode post is lower than the cover plate, and thereby batteries can effectively avoid short circuits.
Description
Technical field
The utility model relates to a kind of shell, relates in particular to a kind of electrokinetic cell shell.
Background technology
Lithium-ion-power cell belongs to the new forms of energy industry, is a kind of advanced pollution-free green energy, is used for the energy of electric bicycle, battery-operated motor cycle, electric tool, electric automobile.High-capacity lithium-ion power battery is on probation in electric automobile, will become one of major impetus power supply of 21 century electric automobile, and will be applied aspect artificial satellite, Aero-Space and the energy storage.
The shell of current driving force battery mainly is metal-back form and aluminum-plastic packaged form membrane, the shell of aluminum-plastic packaged form membrane is damaged easily, and metal-back mostly is a cuboid, the Chinese utility model patent " a kind of metal shell structure of lithium-ion-power cell " of application for example, the patent No.: 200820137556.5, this kind structure exists the assembling procedure complexity, defectives such as the easy short circuit of battery plus-negative plate.
Summary of the invention
The purpose of this utility model is to provide a kind of electrokinetic cell shell, and this shell is symmetrical hierarchic structure and is convenient to assembling.
The utility model is achieved like this, it comprises housing and cover plate, it is characterized in that: cover plate connects housing, and housing is the groove that is symmetrical notch cuttype, housing has three rank, first rank are the housing base plate, the hold electrodes body, and second rank are the lug position, be respectively applied for the anode ear and the negative electrode lug of fixed electrode body, the 3rd rank are the cover plate position, and the length and the width of cover plate are not less than housing, and housing is provided with liquid injection hole.
Outside, negative electrode lug described in the utility model position is connected with conduction connector.
Anode ear described in the utility model position end is connected with pole.
The quantity of pole described in the utility model is 1-5.
Positive Poles height described in the utility model is lower than the height of housing base plate.
Technique effect of the present utility model is: adopt notch cuttype groove housing, the shell of electrokinetic cell is rationalized more, assembly operation is simple and convenient, is not easy to damage electrode, and the weld jig of cover plate and housing requires to reduce, and saves production cost.The pole position is lower than cover plate in addition, and battery is effectively avoided being short-circuited each other.
