This type of clock battery is assembled according to the requirements and applied to notebook computers and power tools. Cylindrical metal canned clock battery is made of cylindrical iron shell for the outer casing of the cylinder. It can withstand the pressure of large discharge gas and is not easy to explode. It is a strong type, but once it explodes, the power may destroy a room. There are still security concerns, such as the recent SONY battery recycling incident. Cylindrical metal canned lithium batteries are packed in a cylindrical iron shell, so the equipment and process are quite complicated and costly; in addition, each lithium battery cell requires a pneumatic valve to regulate the pressure inside the lithium battery, but also Increasing the component cost of each silver battery cell; the cylindrical metal canned lithium battery with a cylindrical metal shell as the outer casing will also have a weight due to the metal casing. 200931701 'The problem of quantity' will hinder the electronic products from being "light, thin and short" The development of small and small.

Convenient for a variety of assembly methods. The advantage of this case is that lithium iron phosphate (LiFeP〇4) is used as a lithium ion secondary battery material, which can exhibit a high discharge specific electric quantity of about 120-150 mAh/g (theoretical specific capacitance is 17〇mAh/g). ), the cycle life can reach hundreds or even thousands of times, easy to make, high security and low cost, etc., 200931701 points. Through the technology of this case, the use of Ming plastic film packaging material as its outer casing 借 borrowing plastic film has the advantages of easy forming, light weight and relatively cheap metal (iron) f shell body. (4), (4) The membrane casing not only lowers the battery outside, but also shouts. In addition, the complexity and cost of the process are also reduced, and the weight problem of the clock battery is also reduced, which is in line with the application trend of "light, thin, short, and small" electronic products. Moreover, the battery can be controlled by the air valve every clock-cell. Because the plastic film itself can adjust the internal pressure by pressing, the space of the original valve can increase the electrode plate by 3mm. It can increase the capacitance of a single lithium ion battery.

The lithium battery body 110 is provided with a positive electrode terminal conductive piece i n and a negative electrode end conductive piece 112, and the aluminum plastic film 12 is coated with the lithium battery body no, but the positive electrode terminal conductive piece U1 and the negative electrode end conductive piece 112 are exposed. About 2 to l〇mm. The aluminum plastic film 120 covers the lithium battery body 11 , and the two half-shaped cylindrical grooves 122 and 123 are formed in the aluminum plastic film 120 , and the clock battery body is covered by folding, and the plastic film 12 is used. The joint region 121 on the crucible is thermally and pressure-bonded, so that the lithium battery body n〇 is fixedly coated on the two half-section cylindrical grooves 22 and 123 of the aluminum-plastic composite crucible. 8 200931701 Cyan again refers to FIG. 3, which is another way of coating the lithium battery body Π0 in the embodiment of the present invention.

The inside of the battery consists mainly of positive electrode, negative electrode, separator and electrolyte. The cylindrical 18650 ion secondary battery is taken as an example. When the positive electrode material is LiFeP〇4, the negative electrode material is artificial graphite. The electrolyte is made of EC/PC/DMC/EMC lMLiPF6, and the formed battery body 110 is overmolded with the aluminum plastic film 120, and after 15 times of charging and charging for 5 times, the battery capacity still retains 95% or more of the original capacity. And the safety test results of crushing, Nail and lmpact will only cause distortion, breakage and breakage, and there is no danger of explosion.

In this case, the lithium plastic film body 120 is coated with a lithium battery body no with a positive electrode material LiFeP〇4/separator/artificial graphite, and the safety and heat stability of the lithium iron phosphate (LiFep〇4) is used. ), the female fullness can be greatly improved, and this production is simpler than the iron can, and the equipment cost and the single cost can be reduced. And using the plastic film packaging coffin as its outer casing, the single battery will be 20% lighter than the cylindrical iron can, and also reduce the weight of the lithium battery, in line with the electronic product "light, thin, short, small" application drive Potential. Moreover, each of the battery cells can adjust the internal pressure without a gas pressure valve, because the aluminum plastic film 12 itself can adjust the internal pressure by pressing, and the space of the original valve air valve can increase the plate. More than 3mm, the capacitance of a single lithium-ion battery can be increased by about 4%. Benning technology improves the complex battery sealing process, while the aluminum plastic film 12〇 itself has the characteristics of light weight, and the lithium battery body 110 with the positive electrode material of lithium iron phosphate u (LiFeP〇4) has long-term storage.
