Description
Technical field
The utility model belongs to the lithium ion battery field, is specifically related to a kind of discharge-rate of lithium ion battery and bipolar ear high multiplying power lithium ion battery of security performance of improving.
Background technology
Lithium ion battery has the output voltage height, specific energy height, discharging voltage balance, the characteristics that have extended cycle life.So lithium ion battery has been widely used in notebook computer, digital camera, field of mobile phones.The present developing direction of lithium ion battery is to the development of motive use type, promptly requires it to have the power of better high rate during charging-discharging and Geng Gao.The high rate during charging-discharging that improves battery will reduce the internal resistance of battery, because under the same voltage, the internal resistance of resistance is low more, the discharging current that can reach is big more, on the other hand, the high internal resistance meeting of battery makes the interior sharply rising of the temperature short time of inside battery, reduce the fail safe of battery, performance to battery itself impacts simultaneously, moreover because the internal resistance of battery is big, cause the ohm voltage drop of battery to become big, can must drop to cut-ff voltage sooner during battery discharge, battery capacity can not be fully utilized.The internal resistance of cell comprises the interface impedance of positive plate impedance, negative plate impedance, positive pole ear impedance, negative lug impedance, electrolyte impedance and pole piece and electrolyte promptly together with the resistance sum between all substances of both positive and negative polarity.Generally speaking, the performance of improving battery all is that the performance that aligns negative electrode active material is improved, and seldom has to improve to reach at the manufacturing process of battery to improve battery performance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of simple in structure, raising battery discharge multiplying power is provided, and guarantees the bipolar ear high multiplying power lithium ion battery of its fail safe.
The object of the present invention is achieved like this: comprise battery container and interior set positive plate and negative plate, positive plate is provided with first anode ear and is installed in the second middle anode ear of positive plate, first anode ear is arranged on an end of positive plate, is installed in the second middle anode ear of positive plate and is arranged on the centre of positive plate and is arranged on the same side with first anode ear; Negative plate is provided with two negative electrode lugs, and two negative electrode lugs are separately positioned on the two ends of negative plate the same side.Described first anode ear is an aluminium pole ears.Described negative electrode lug is the nickel lug.Ultrasonic being welded on the positive plate of second anode ear that described first anode ear is middle with being installed in positive plate.Described two ultrasonic being welded on the negative plate of negative electrode lug.
The utlity model has following advantage:
1, the utility model simplicity of design, rational in infrastructure, effect obviously, be fit to use of large-scale production,
2, the utility model structure is optimized, and has reduced the internal resistance of battery, has improved the charge-discharge magnification of battery, has improved its fail safe simultaneously.
