Abstract
The utility model belongs to the field of electrical devices, and particularly relates to a high power cylinder battery. A battery unit is composed of an electric core, an anode cover, electrolyte solution and a shell body, wherein the electric core is formed by winding of a positive pole piece, a negative pole piece and a diaphragm. After the electric core is wound and installed into the shell body, pole lugs of an anode and a cathode are tailored from side edges of the anode and the cathode which are not coated by anode and cathode materials, and the pole lugs are respectively welded on an anode combination cover and the bottom of the shell body. The high power cylinder battery is simple in productive technology and low in cost. Produced batteries have high specific power and specific energy and can be used as an energy storing device for various equipment and transportation vehicles, and as an uninterruptible power supply, an emergency power supply and the like for various transformer substations, operating rooms in hospitals, nuclear reactor control and safeguard facilities, aerospace communication facilities and radio communication. The high power cylinder battery has the advantages of long service life, low cost, no maintenance and the like.
Description
Technical field
The utility model belongs to a kind of battery in the electrical installation.Can be used as the energy storage device of the various equipments and the vehicles, and uninterrupted power supply of all kinds of substation, hospital operating room, nuclear reactor control, protective equipment, space flight communications service, radio communication, emergency power supply etc.
Background technology
In existing cylindrical battery production technology, what pole piece was taked is the mode that batch (-type) applies, and is intermittently locating the welding conducting strip as lug again after the pole piece cutting; Not only increased complexity, difficulty and the cost of technology, and because lug area and limited amount cause the internal resistance of cell bigger; Anti-high-power poor performance, promptly battery high magnification charge is poor, and specific power is not high; Use is very limited, and is not suitable on equipment such as electric motor car, using.In addition owing to be welded on the lug non-activity material on the negative pole, on lug, produce Li dendrite easily during charging and influence the fail safe and the cycle life of battery.
Summary of the invention
The purpose of the utility model is a kind of high-power battery of design again for the above-mentioned defective that overcomes existing battery, makes that it has that internal resistance is low, specific power is high, technology is simple, low cost of manufacture, is suitable for advantage such as large-scale production.
The utility model is to rely on following technology to realize: when positive pole 7 and negative pole 8 coatings; Reserve anodal side 2 that is not coated with positive electrode 1 and the negative pole side 4 that is not coated with negative material 3 respectively at a side; After coating is accomplished; Anodal side 2 is cut into the Great Wall shape with negative pole side 4, and the part that anodal side 2 and negative pole side 4 are not cropped is respectively as positive pole ear 5 and negative lug 6; With the positive pole that cuts 7, negative pole 8,,, and weld together with outer casing bottom 10 with the battery case 12 of packing into after negative lug 6 bendings according to barrier film 9, negative pole 8, barrier film 9, anodal 7 sequential volume coiled electricity core; After electric core and outer casing bottom 10 welded together, positive pole ear 5 and anodal combination cover cap 11 are fitted together through encapsulant 13.
Battery of the present invention has higher specific energy and specific power (specific energy is greater than 80Wh/kg, high-specific-power surpass 3000W/kg), has characteristics such as life-span long (cycle life is above 1500 times), cost be low, non-maintaining.
