Description
Technical field
The utility model
A kind of thin lithium ion batteryBelong to the secondary cell field, particularly relate to a kind of slim lithium ion battery.
Background technology
Modern society's information is flourishing; Various magnetic cards, smart card (IC-card), identification card (ID card), bank card, radio-frequency card (electronic tag, RFID), Electronic Paper etc. are arisen at the historic moment; The not charged source of card in the past, amount of information is little, confidentiality is poor, is developing the card in charged source; Improve amount of information and confidentiality, thin battery is proposed demand.Present thin lithium ion battery thickness on the market is many at 0.4 ± 0.05mm, and the card thickness of standard is 0.8 ± 0.04mm, requires thin lithium ion battery thickness at 0.15 ~ 0.35mm, and is optimum at 0.2 ~ 0.3mm.Present thin lithium ion battery can only be used for nonstandard, thicker card.
The patent No. is that the Chinese patent of 10L200820093364.9 discloses the secondary slimline battery; Use envelope lug in advance, promptly lug glue in encapsulation in advance on aluminum strip and the nickel bar also can be described as band glue lug; To seal the lug metallic object in advance is welded on anode and the negative electrode; Use aluminum-plastic composite membrane to do packaging film, will seal lug in advance and be packaged together, make slimline battery with aluminum-plastic composite membrane.This method has two shortcomings; That (1) metallic object of pre existing envelope lug is the thinnest is 0.07 mm; That lug glue is the thinnest is 0.07 mm; Be exclusively used in the aluminum-plastic composite membrane of lithium ion battery the thinnest be 0.088mm, the thinnest battery that can make is the thinnest aluminum-plastic composite membrane of bilayer, the thinnest lug glue of bilayer, the thinnest metallic object of one deck totally 0.386 mm, such thickness is too thick for smart card; (2) seal aluminium pole ears in advance and follow anodal aluminum foil current collector through ultrasonic spot welding, after receiving ultrasonic vibration and pushing, anodal aluminum foil current collector becomes fragile, and is easy to fracture, and rate of finished products is very low.
The patent No. is that the Chinese patent of 10L98103781.X discloses thin battery; Electrode terminal that is lug have conductive member netted or porous to form; The conductive member material is introduced from electrochemical stability and is considered that aluminium, gold and carbon are suitable for doing positive pole ear most by optional in carbon, nickel, aluminium, copper, tungsten, stainless steel, iron, silver, gold and their alloy.Be actually be out of use gold and carbon and do positive pole ear.This method is done lug with conductive member netted or porous, and intensity is poorer, and needing to increase thickness could seal and don't rupture reliably.
The patent No. is that the Chinese patent of 10L201020504895.X discloses a kind of thin battery, uses aluminum-plastic composite membrane to do thin lithium ion battery, need not seal lug in advance; Positive plate and negative plate reserve anode ear and negative electrode lug respectively; When lug need encapsulate with aluminum-plastic composite membrane,, use heat sealing machine that lug and aluminum-plastic composite membrane are packaged together in the corresponding aluminum-plastic composite membrane punching of lug; Aluminum-plastic composite membrane punching place exposed portions serve anode ear and negative electrode lug can be made the battery below 0.3 mm like this.This method has three shortcomings, and (1) anodal aluminum foil current collector and negative copper foil collector be directly with aluminum-plastic composite membrane encapsulation, has aluminium foil and Copper Foil rupture break inside especially, problem that rate of finished products is low; (2) anodal aluminum foil current collector and negative copper foil collector directly with the aluminum-plastic composite membrane encapsulation, do not add lug glue, depend the adhesive layer of aluminum-plastic composite membrane alone, and be bonding unreliable, has the chance of seepage or steam, oxygen invasion, the battery poor reliability, and the life-span is short; (3) this kind way can not add lug glue, and the glue-line thickening more is prone to the disconnected lug of extruding envelope, and lug glue can block the hole that aluminum-plastic composite membrane dashes in advance again.
The conventional thin lithium ion battery uses aluminium foil or aluminium net to do positive pole ear, and aluminium foil or aluminium net fusing point are low, and intensity difference under intensity difference, especially the high temperature heat seal condition will be carried out battery and just need add thick aluminum foil, forms contradiction with wanting to do thin battery; Use anodal aluminum foil current collector and negative copper foil collector directly with aluminum-plastic composite membrane encapsulation, also have the problem that the low problem of the fracture of aluminium foil and Copper Foil, rate of finished products and bonding unreliable, battery poor reliability, life-span lack.
The utility model content
The purpose of the utility model is to existing technical barrier, and provides a kind of that more approach, the existing thickness limit of breakthrough
A kind of thin lithium ion battery
At first analyze the manufacture method of existing use aluminum-plastic composite membrane packing, directly reserve anode ear with negative electrode lug is the most convenient, and there is the problem of sealing the lug that breaks when sealing in this method with positive plate and negative plate.Tracing it to its cause, is that intensity is low because the fusing point of aluminium foil is lower, and especially under 200 ℃ of heat-sealing temperatures, the intensity of aluminium declines to a great extent, the lug of hot melt state gluing aluminium foil, stand the heat sealing machine extruding, the aluminium foil drawing crack.More specifically, the width＜aluminum-plastic composite membrane closedtop hem width degree＜lug glue width of general heat-sealing head, heat-sealing back lug glue protection lug metallic object can not followed aluminum metal body contact in the aluminum-plastic composite membrane and short circuit; But during heat-sealing; Heat-sealing head is depressed and, and the lug glue fusion of periphery and lug fluid sealant far away slightly is molten is pullled effect to the lug metallic object; And heat-sealing head presses down, and the lug metallic object is pullled fracture by lug glue.Attempt to widen the aluminium foil width and gain in strength, just need widen lug glue, produce bigger pulling force, aluminium foil drawing crack likewise.Only add thick aluminum foil, just can gain in strength, opposing lug glue and heat sealing machine extruding force.Here it is, and lug supplier can only provide the reason of the above aluminium pole ears of 0.07mm thickness, and thinner aluminium pole ears can not be provided.Need not be with the glue lug, oneself add when encapsulating that lug glue makes the sealing of lug place tight, reason is the same, and aluminium foil can drawing crack.Add thick aluminum foil and form contradiction with doing thin battery.When using aluminium foil to do plus plate current-collecting body to hold concurrently wrapping film, there is the problem of heat sealing machine extruding aluminium foil drawing crack equally, only if aluminium foil is enough thick.Aluminium foil is also arranged in the aluminum-plastic composite membrane, because resistant to elevated temperatures nylon layer protection is arranged, nylon layer cannot not be molten under the heat-sealing temperature, can protect the aluminium foil in the aluminum-plastic composite membrane not rupture.
Analyzing has any high-strength material can do battery afflux liquid again, sees table 1.
The performance parameter of several kinds of metal materials of table 1.
| Material | Fusing point ℃ | Tensile strength MPa | Mohs' hardness | Density g/cm3 |
| Aluminium | 660 | 180 | 3 | 2.702 |
| Copper | 1083 | 250 | 3 | 8.920 |
| Nickel | 1453 | 660 | 4 | 8.902 |
| Titanium | 1668 | 1800 | 6 | 4.506 |
