Abstract
The utility model belongs to a big-capacity lithium ion battery structure. It contains a cylindrical battery casing, a battery upper cover, a battery bottom cover, a positive electrode, a diaphragm, a negative electrode, a positive terminal and a negative terminal. The utility model is characterized in that the positive electrode, the diaphragm and the negative electrode of the battery roll on one aluminous tube, forming a columnar core which is placed inside the battery shell. The aluminous tube in the core connects with the battery casing to be integration through the battery bottom cover. By the way that the positive electrode, the diaphragm and the negative electrode enwind around the aluminous tube tightly and are put inside the cylindrical battery shell together, it not only ensures the tight assembly of the battery positive electrode and the negative electrode, but also because the aluminous tube connects with the battery casing to be integration through the battery bottom cover, ensures the heat coming from the high-capacity battery in use can conduct to the battery casing and shed outside, reducing the heat cumulate inside the battery, improving the battery performance greatly. It is very suitable for high-capacity lithium ion battery like motor-driven bicycle, electricautomobile, etc.

The high capacity lithium ion battery structure, the case material that is characterized in described battery is an aluminum alloy materials, the negative terminal of described battery is connected by the insulating sealer insulated enclosure with battery cover.
Advantage and the good effect that the utlity model has are: closely be wrapped on the aluminum pipe by adopting positive pole, barrier film and negative pole, put into the cylindrical battery housing together, both guaranteed the close fit of battery positive and negative electrode, be connected as a single entity by battery bottom and battery container owing to aluminum pipe again, guaranteed that high capacity cell heat of generation when work can be transmitted to battery container very soon and come out, reduced of the accumulation of battery heat, improved the performance of battery greatly in the battery the inside.
Description of drawings
Fig. 1 is the schematic diagram of a kind of high capacity lithium ion battery structure of the utility model embodiment.
Label among the figure is respectively: 1 is positive terminal, and 2 is insulating sealer, and 3 is cell cover, and 4 is battery container, and 5 is anodal, and 6 is barrier film, and 7 is negative pole, and 8 is aluminum pipe, and 9 is bottom, and 10 is negative terminal.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following examples now, and conjunction with figs. is described in detail as follows:
Please refer to Fig. 1: the employing diameter is 45mm, and wall thickness is 0.5mm, and the stainless steel material that highly is 180mm is as battery container 4, and the diameter of aluminum pipe 8 is 8mm, and wall thickness is 1mm, and the aluminum pipe height is 150mm.Positive pole 5, barrier film 6, negative pole 7 are wrapped in and form the battery core body on the aluminum pipe 8.The external diameter of battery core body equates with the internal diameter of battery container 4, and the battery core body is inserted in the battery container, adopts riveted joint connection anodal 5 and positive terminal 1, and negative pole 7 and negative terminal 10 riveted joints make the middle aluminum pipe 8 of battery core body be connected with battery bottom 9 simultaneously.Because what battery container 4 adopted is stainless steel material, positive terminal 1 is connected by insulating sealer 2 insulated enclosures with cell cover 3, and negative terminal 10 can form one with bottom 9.With the method sealing-in that cell cover 3, battery container 4, bottom 9 weld by laser welding or argon arc, the electrolyte by the injection of the liquid injection hole on battery cover requested number discharges and recharges activation then, is prepared into the lithium ion battery that needs capacity.Because design has the aluminum pipe 8 of hollow in the middle of the battery core body, aluminum pipe 8 is connected with battery container 4, and the heat that produces when battery operated can be transmitted to the battery container surface very soon, has reduced the accumulation of battery heat in the battery the inside, has improved the performance of battery.
