Abstract
The utility model discloses a kind of inside lithium ion cell insulation system, it is characterized in that it comprises insulator (1), insulator (1) is arranged between battery pole group (2) and shell (3), insulator (1) is positioned at battery pole group (2) outside and battery pole group (2) is wrapped up, shell (3) is enclosed within the outside of insulator (1), and insulator (1) is distributed with some roads impression (4).The utility model has not only possessed insulation function, facilitates pole group simultaneously and enters shell, substantially increase production efficiency, reduce the probability of pole group and battery container short circuit.
Description
Technical field
The utility model relates to a kind of inside lithium ion cell insulation system.
Background technology
Battery in use, burr can penetrate barrier film, cause battery short circuit, thus affect the fail safe of power-supply system, therefore in use must guarantee that electrokinetic cell in use can not penetrate the phenomenon that battery short circuit appears in barrier film by Yin Maoci, have the structure adopting barrier film parcel battery pole group at present, but this structure installment is inconvenient.
Summary of the invention
The utility model provides a kind of inside lithium ion cell insulation system, and it has not only possessed insulation function, facilitates pole group simultaneously and enters shell, substantially increase production efficiency, reduce the probability of pole group and battery container short circuit.
The utility model have employed following technical scheme: a kind of inside lithium ion cell insulation system, it comprises insulator, insulator is arranged between battery pole group and shell, insulator is positioned at battery pole group outside and battery pole group is wrapped up, casing, in the outside of insulator, is distributed with some roads impression on insulator.
Described insulator is set to polypropylene material.Four sides of described insulator are decentralized architecture, distribute four road impressions on insulator, per pass impression is horizontal indentation, and insulator four sides are upwards gathered rear formation body along battery pole group and battery pole group wrapped up, and when gathering, four sides of insulator are in the upwards bending of impression place.
The utility model has following beneficial effect: after have employed above technical scheme, the utility model comprises insulator, insulator is arranged between battery pole group and shell, insulator is positioned at battery pole group outside and battery pole group is wrapped up, casing is in the outside of insulator, be distributed with some roads impression on insulator, so not only possesses insulation function, reduce the probability of battery pole group and battery container short circuit, because insulating case insulating case is set to polypropylene material, so just have and have certain pliability, smooth surface, insulation property are better, there is good stress crack resistance performance, there are very high flexible life and certain degree of hardness, can by making impression in manufacturing process, simultaneously because polypropylene material surface is more smooth, more easily enter shell, then in use just can fold along impression place and not easy fracture, after entering shell, battery burr cannot penetrate, enter in this procedure of shell to add insulating case in battery pole group, and then carry out into shell, along with the progress entering shell, built-in electrical insulation structure becomes overall structure gradually by decentralized.
