Description
Technical field
[0001] the present invention relates to a kind of lithium ion battery and ultracapacitor, a kind of specifically explosion-proof low internal resistance Li-ion battery and ultracapacitor.
Background technology
Along with the progress of science and technology and the development of society, 21 century has got into the electronic information epoch, and the electronic information epoch have higher requirement for power supply, and the demand of portable power source increases fast.Lithium ion battery is as the present ideal in the world and the highest chargeable chemical cell of technology content; Because the advantage that lithium ion battery has high voltage, high power capacity, has extended cycle life, security performance is good; It is had broad application prospects in many-sides such as portable electric appts, electric automobile, space technology, national defense industry; Be widely used in mobile phone, laptop computer, video camera, electric bicycle, space flight and aviation, military mobile communication facility and fields such as equipment and electric automobile, its demand is with increasing.
The ion battery that uses in the market and the structure majority of ultracapacitor are Soft Roll polymer Li-ion battery and ultracapacitor; The lithium ion battery of this kind structure and ultracapacitor have certain disadvantages and weak point; 1., owing to mostly during battery and ultracapacitor assembling in the past adopt the scolding tin method of attachment be in particular in:, the battery of this assemble method and ultracapacitor shock resistance are weak, the internal resistance loss is big.2., after the assembling of soft-package battery and ultracapacitor, owing to be the Soft Roll structure, so a little less than the ability of destructive factors such as shock resistance, extruding.
Summary of the invention
The objective of the invention is to provide a kind of simple and reasonable, shock resistance is strong, the internal resistance loss is little, long service life, explosion-proof low internal resistance Li-ion battery and ultracapacitor that fail safe is good.
The objective of the invention is to realize like this; This lithium ion battery and ultracapacitor comprise that shell, battery cell, heating panel, plastic insulation covering, loam cake, electrode draw screw mechanism; Be provided with heating panel between said two adjacent battery cells; The battery main body that a plurality of battery cells and heating panel fit together formation is set up in the enclosure; Plastic insulation covering is sleeved on the upper end of battery main body, and loam cake is arranged on above the shell one end plastic insulation covering, and described electrode is drawn screw mechanism and is connected on the electrode outlet line through plastic insulation covering and loam cake.
One side of described shell has interface.
Advantage of the present invention and good effect:
1, the present invention rivets owing to adopting lead-in wire directly to turn back, and anode and cathode respectively has only a riveting point, and the shock resistance, the internal resistance loss that have improved battery so greatly reduce.
2, the present invention is owing to improve battery case; In the process that shell is produced; When the manufacture craft at employing associating angle is heaved after battery runs into short circuit or bump like this; Associating angle sealing part can break away from automatically, has exempted the hidden danger of the excessive generation blast of cell internal pressure, has improved the ability of resisting extraneous destructive factor.
3, exit adopts the method for screw assembling, has reduced the internal structure project, has improved the performance of assembling soft-package battery, has made things convenient for the production capacity to single battery parallel connection, series connection simultaneously, thereby has improved productivity greatly.
4, because high capacity cell can produce certain heat when discharging and recharging, so newly design a kind of heat-conducting plate that is added between battery and battery, can reduce heat like this and produce, thus the performance and the life-span of improving battery.
