Description
Technical field
This utility model relates to a kind of lithium ion battery, the polymer Li-ion electricity of a kind of cylindrical structure
Pond, belongs to technical field of lithium ion.
Background technology
At present, the minicell such as Mini-otophone on the market typically uses metal shell, Heavy Weight, actual is using
There is the short circuit phenomenon caused because of the metal shell problem of battery in Cheng Jingchang；Because the metal shell of battery result in galvanomagnetic-effect
And the electromagnetic interference produced, affect hearing aid effect；Because battery galvanomagnetic-effect causes the cycle life of battery relatively low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides the polymer lithium of a kind of cylindrical structure
Ion battery, the structure of its uniqueness has bigger volume space, and is assemblied in electronic product, and the installation site occupied is relatively
Little.
The technical scheme provided according to this utility model, the polymer Li-ion battery of a kind of cylindrical structure, including electricity
Pond shell, positive plate, negative plate, positive plate lug and negative plate lug, is characterized in that: battery case includes frustum of a cone section and circle
Column body segment, frustum of a cone section and shell portion are vertically connected with integral, and frustum of a cone section and shell portion are one-body molded；Battery case
Upper half cavity is cavity, and the lower half cavity of battery case is annular seal space, encapsulation positive plate and negative plate in annular seal space；Battery case
Upper end is respectively arranged on the left side and the right side positive plate lug and negative plate lug；Positive plate lug lower end is stretched in battery case and positive pole
Sheet connects, and negative plate lug lower end is connected with negative plate in stretching into battery case.
Further, battery case uses the aluminum plastic film material of monolayer to make.
Further, positive plate and negative plate lay respectively at the left and right sides of battery case.
Further, positive plate lug and negative plate lug are symmetrical set.
Compared with the prior art this utility model has the advantage that
This utility model simple in construction, compact, reasonable, improve reliability, safety that sonifer uses, again can be significantly
Improve the ruggedness of battery；About 10%-15% lighter than the traditional hearing aid battery of equivalent capability；There is bigger volume space, and
And be assemblied in electronic product, the installation site occupied is less.
Accompanying drawing explanation
Fig. 1 is this utility model front view.
Description of reference numerals: 1-battery case, 1.1-frustum of a cone section, 1.2-shell portion, 2-positive plate, 3-negative plate,
