Abstract
The utility model relates to a post-type lithium battery, which comprises a casing and a current collector. The casing is internally orderly provided, from outside to inside, with a lithium piece, a glass fiber bottom film, a four-fluorin bottom film, a side film and an anode carbon bag. The upper end of the casing is sealedly welded with a cover cap which is provided with an injection hole and a gas sealing structure. Moreover, an upper cover film is arranged above the anode carbon bag inside the casing, and an anode positioning rod is sleeved between the upper cover film on the current collector and the cover cap. By the anode positioning rod fixing the upper cover film, the utility model prevents the upper cover film, the anode carbon bag and other inside components from changing positions, thereby avoiding such problems as short circuit in battery and ineffective battery in using process.
Description
Technical field
The utility model relates to a kind of column type lithium cell, thereby especially a kind ofly can prevent internal short-circuit of battery by the self-contained battery internal part, the lithium battery of battery failure.
Background technology
Fig. 1 is the structure chart of common column type lithium cell, as shown in Figure 1, comprise that ecto-entad is placed lithium sheet 5, glass fibre counterdie 7, tetrafluoro counterdie 8, limit film 4 and anodal carbon bag 3 successively in shell 6 and collector 9, the shell 6, the upper end of shell 6 and block 10 seal weldings, block 10 is provided with liquid injection hole 11 and airtight construction 12, be provided with above the internal positive carbon bag 3 of shell 6 adopt that fibreglass diaphragm makes on epiphragma 2.
The column type lithium cell of this kind structure is owing to exist the space between last epiphragma and block, so going up the position and the shape of epiphragma when battery is inverted changes easily, internal parts such as last epiphragma and anodal carbon bag move the position easily, cause internal short-circuit of battery easily, battery failure.
The utility model content
The purpose of this utility model is at the deficiency of existing column type lithium cell, can prevent internal short-circuit of battery by the self-contained battery internal part, the lithium battery of battery failure thereby provide a kind of.
To achieve these goals, the utility model provides a kind of column type lithium cell, comprise shell, be provided with collector in the described shell, it is characterized in that ecto-entad is placed lithium sheet, glass fibre counterdie, tetrafluoro counterdie, limit film and anodal carbon bag successively in the described shell, the upper end of described shell and cap sealed welding, described block is provided with liquid injection hole and airtight construction, be provided with above the described anodal carbon bag in the inside of described shell adopt PTFE on epiphragma, be arranged with anodal backstay between epiphragma and the block on the collector.
Adopt the utility model of said structure, fix epiphragma by anodal backstay, thereby prevent internal part position changes such as epiphragma and anodal carbon bag.
In addition, for the battery of big model, because its inner space is bigger, the structure of inside battery is more loose, if can adopt structure of the present utility model, its fixed effect can be more obvious.
Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Description of drawings
