Abstract
The invention discloses a kind of lithium rechargeable battery for possessing self heating function.It includes battery core, outer packing and the electrolyte that is filled in outer packing for packaging electric core, positive pole and negative pole are drawn in battery core, the metal foil positioned at battery core side is additionally provided with outer packing, the metal foil is provided with the 3rd pole, can connect or disconnect between the 3rd pole and negative pole.After above-mentioned structure, under cryogenic can be by the way that the 3rd pole of metal foil and negative pole be attached into the short circuit caused between both positive and negative polarity, moment has larger current internal temperature of battery is preferably lifted by being generated heat after metal foil, ensure that lithium ion battery has higher capacity to play in low temperature environment, and the metal foil of its interpolation make it that heat production efficiency far is elevated higher than the mode and internal temperature of battery of external heat unanimously more preferable；Also reduce battery cost and improve battery energy density, additionally it is possible to preferably adapt to varying environment temperature.
Description
Technical field
The present invention relates to a kind of lithium rechargeable battery, specifically a kind of lithium ion secondary for possessing self heating function
Battery.
Background technology
More and more extensive with the use of electronic product, flexible packing lithium ion battery has that in light weight, capacity is big, energy is close
The advantages that high is spent, is widely used in the every field such as camera, notebook and mobile phone, existing lithium rechargeable battery is typically all
By shell, electrolyte and battery core in shell are formed, it is well known, however, that the use of lithium ion battery is by environment temperature shadow
Sound is larger, and its capacity cannot play generally in low temperature environment, particularly cold winter, often make it that lithium ion battery is difficult
Used with remaining effective, typically improve the performance of capacity by the way of external heat in the prior art, so that
Cost is high and temperature lifting also unobvious, use reliability are poor.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of reasonable in design, manufacturing cost is low and can effectively improve
The lithium rechargeable battery for possessing self heating function of capacity under low temperature.
In order to solve the above-mentioned technical problem, the lithium rechargeable battery for possessing self heating function of the invention, including battery core,
Outer packing and the electrolyte that is filled in outer packing for packaging electric core, draw positive pole and negative pole in battery core, in outer packing
The metal foil positioned at battery core side is additionally provided with, the metal foil is provided with the 3rd pole, can between the 3rd pole and negative pole
Connection disconnects.
The battery core has the positive plate and negative plate of superposition, and the positive pole draws from positive plate, and the negative pole is from negative
Drawn on pole piece, the metal foil is arranged side by side with positive plate and negative plate.
The outer packing is aluminum plastic film.
After above-mentioned structure, increase the insertion of metal foil in soft-package battery, and drawn as the 3rd pole, thus existed
Under cryogenic conditions can by the way that the 3rd pole of metal foil and negative pole is attached into the short circuit caused between both positive and negative polarity, moment have compared with
High current makes internal temperature of battery preferably be lifted by being generated heat after metal foil, ensures lithium ion battery in low temperature environment
There is higher capacity to play, and the metal foil of its interpolation causes heat production efficiency far to be higher than the mode and battery of external heat
Internal temperature is elevated unanimously more preferable；In addition, also reduce battery cost and improve battery energy density, additionally it is possible to more
Good adaptation varying environment temperature.
Brief description of the drawings
Fig. 1 is the structural representation for the lithium rechargeable battery that the present invention possesses self heating function.
Embodiment
With reference to the accompanying drawings and detailed description, the lithium rechargeable battery for possessing self heating function of the present invention is made
It is further described.
As illustrated, the lithium rechargeable battery for possessing self heating function of the present invention, including battery core 1, for encapsulating electricity
The outer packing 2 of core and the electrolyte 3 being filled in outer packing, described outer packing 2 are aluminum plastic film, and there is battery core superposition to set
Positive plate 7 and negative plate 8, positive pole 3 drawn from positive plate 7, and negative pole 4 is drawn from negative plate 8, is also set up in outer packing 2
There is the metal foil 5 positioned at battery core side, metal foil 5 is arranged side by side with positive plate 7 and negative plate 8, and metal foil 5 is provided with the 3rd pole
6, it can connect or disconnect between the 3rd pole 6 and negative pole 4.
Its operation principle is：
Control metal foil ohmic internal resistance within the specific limits, under cryogenic by the way that the 3rd pole of metal foil is entered with negative pole
Row connection causes short circuit between both positive and negative polarity, moment have larger current by generated heat after metal foil make internal temperature of battery obtain compared with
Good lifting, ensure that lithium ion battery has higher capacity to play in low temperature environment.
