Technical field
The utility model relates to cell art, particularly relates to a kind of polymer battery.
Background technology
Lithium polymer battery (Li-polymer, also known as high-polymer lithium battery): it is also the one of lithium ion battery, but have compared with liquid lithium battery (Li-ion) that energy density is high, more miniaturized, ultrathin, lightweight, and the multiple clear superiority such as high security and low cost, be a kind of novel battery.In shape, lithium polymer battery has ultrathin feature, can coordinate the needs of various product, is made into the battery of any shape and capacity.
Compared with liquid lithium ionic cell, polymer Li-ion battery has can the advantage such as thin type, arbitrary areaization and arbitrary shape.Therefore with the lighter plastic-aluminum combined thin film fabrication battery case of quality, thus the specific capacity of whole battery can be improved; Polymer Li-ion battery can also adopt macromolecule to make positive electrode, and its energy will be higher than current liquid lithium ionic cell.In addition, polymer Li-ion battery all increases than lithium ion battery in operating voltage, charge and discharge circulation life etc.Based on above advantage, polymer Li-ion battery is described as lithium ion battery of future generation.
Polymer battery domestic at present to encapsulate after usual battery core dress glue frame directly low-pressure injection molding, this encapsulation scheme is stricter for battery core thickness requirement, the controlled thickness deviation of polymer battery core manufacturer is ± 0.15mm, and the clearance space allowed during our low-pressure injection molding is in 0.1mm, so the necessary stepping of battery core before injection moulding, thin battery core needs to paste after PET sheet increases thickness just can carry out injection moulding, comparatively bothers; In addition, if battery core is partially thin, during injection moulding, will overflow glue on battery core surface, not only affects outward appearance, also affect cell thickness size.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model can solve battery surface evenness in preparation process while there are provided a kind of convenient production, also can play again the polymer battery of protection very well to battery core.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of polymer battery, comprise polymer battery core, plastic frame and baffle, described plastic frame is set in the surrounding of described polymer battery core, and baffle is arranged on the side that described plastic frame is arranged with electrode hole; The side of described polymer battery core is also provided with the plastic plate of low-pressure injection molding gained, and the side being close to plastic plate is provided with steel disc, and the opposite side of described polymer battery core is also provided with corresponding lower steel disc, and described upper and lower steel disc fixes on described plastic frame.
Preferably, described plastic frame is made up of all around four sidewalls, described front side wall is provided with electrode hole with the electrode corresponding section of polymer battery core, described left and right sidewall is provided with and groove, the dual-side of described upper and lower steel disc bends inwards, and described kink is fastened in the groove of described plastic frame accordingly.
Preferably, the rear wall of described plastic frame is also provided with clamping hole, and the back side edge of described lower steel disc is also provided with the card base corresponding with described clamping hole.
Preferably, the both sides pressing close to polymer battery core described in are also provided with gelatinous layer.
Preferably, the front side wall of described polymer battery core or rear wall also offer excessive glue groove.In order to attractive in appearance, finally trade mark overcoat can also be provided with outside described polymer battery.
The utility model is by establishing upper and lower steel disc in polymer battery core both sides, and described upper and lower steel disc is fixed on plastic frame by kink and card base, and in injection molding packaging process, about two two steel discs can ensure the evenness of battery surface.When battery core is partially thin, the excessive glue in injection moulding process can flow to deposit and be between electrostrictive polymer core and steel disc, and in the excessive glue groove of polymer battery core, can not affect overall thickness and aesthetic appearance.
