Abstract
The invention discloses a hot pressing plate silica gel sleeve. With the hot pressing plate silica gel sleeve, the polymer lithium ion battery polymerization effect can be ensured, and the problem of poor local polymerization effect due to uneven battery thickness can be effectively solved. The hot pressing plate silica gel sleeve comprises a silica gel sleeve body, wherein the silica gel sleeve body is nested on the surface of the hot pressing plate, two guide column through holes and a temperature measurement through hole are arranged on the upper part of the silica gel sleeve body, and a side surface of the silica gel sleeve body is provided with a notch. With the hot pressing plate silica gel sleeve adopting the structure of the present invention, the structure is simple, and the operation is convenient; the uneven local stressing during the battery hot pressing process is avoided, the generation of the poor polymerization is reduced, and the important significances are provided for ensurences of the battery performance and improvement of the production efficiency.
Description
Technical field
The present invention relates to a kind of lithium ion battery production process equipment, the copper heating platen silica gel sheath that especially a kind of automatic hot press uses.
Background technology
Polymer Li-ion battery is the lithium ion battery of a new generation, and except that electrolyte was solid gel polymer rather than liquid electrolyte, all the other and common lithium ion battery were basic identical.Compare with liquid lithium ionic cell, but polymer Li-ion battery has advantages such as thin typeization, arbitrary areaization and arbitrary shapeization, solid electrolyte can not disintegrate in charging process just as a sealing gel easily naturally.
Polymer Li-ion battery has miniaturization, slimming, light-weighted characteristics, and its occupation rate of market increases year by year, particularly some changes of bringing to movable electrical appliances of polymer Li-ion battery.Polymer battery just is familiar with by designers such as increasing handheld device, notebook computers and is accepted.
Hot pressing process is an one procedure very important in the polymer Li-ion battery production process; Through at a certain temperature; Flexible-packed battery after the fluid injection is applied certain pressure, keep certain hour, realize the fusion of active material, binding agent, barrier film and electrolyte; Through colding pressing it is cooled off, hardens then, reach the purpose of battery typing.Owing to inside battery structural design reason, battery surface thickness everywhere is also inconsistent, so when battery hot pressing; Directly use copper briquetting that battery is carried out hot pressing; Everywhere stressed and inhomogeneous of battery surface the relatively poor phenomenon of local polymerization effect occurs through regular meeting, influences battery performance.
Summary of the invention
The technical problem that the present invention will solve provides and a kind ofly can guarantee the polymer Li-ion battery polymerization effect, effectively solves because the battery local polymerization effect that the causes in uneven thickness heating platen silica gel sheath of good problem not itself.
For addressing the above problem, a kind of heating platen silica gel sheath of the present invention comprises the silica gel sheath body, and this body is nested in surface of heating platen, and two lead through holes and a thermometric through hole are left in the top, and the body side is provided with notch.
Adopt the heating platen silica gel sheath of structure of the present invention, simple in structure, easy to operate, avoided the local pressure in the battery hot pressing uneven, reduced the bad appearance of polymerization, to guarantee battery performance, enhance productivity significant.
Description of drawings
Fig. 1 is the copper thermal pressing board structure sketch map that automatic hot press uses in the prior art.
Fig. 2 is the structural representation of heating platen silica gel sheath of the present invention.
Embodiment
In order to make those skilled in the art person understand technical scheme of the present invention better, the present invention is done further detailed description below in conjunction with accompanying drawing and execution mode.
As shown in Figure 2, heating platen silica gel sheath of the present invention comprises silica gel sheath body 3, and this body 3 is inserted in its inside from the top of copper heating platen 1 with copper heating platen 1.
Two lead through holes 4 are left in said silica gel sheath body 3 tops, are used for when nested copper heating platen 1, and the steel lead 2 on the copper heating platen 1 can pass through this lead through hole 4 smoothly.
A thermometric through hole 5 is also left in said silica gel sheath body 3 tops, and this thermometric through hole 5 is used for conveniently the temperature of copper heating platen 1 being measured.
The side of said silica gel sheath body 3 is provided with notch 6, and through this notch 6, the inside heating tube of copper heating platen 1 and thermocouple wire can be drawn in silica gel sheath body 3 inside.
In the course of the work, silica gel sheath body 3 is enclosed within on the copper heating platen 1,, battery is put into two copper heating platens 1 centres then through jaw gripping battery airbag; The action of hot pressing cylinder; Copper heating platen 1 mutual extrusion, the temperature of copper heating platen 1 conducts to battery surface through silica gel sheath body 3, and battery surface receives certain pressure uniformly everywhere; After keeping certain hour, the pole piece of inside battery, barrier film, binding agent and electrolyte merge each other; Hot pressing finishes, and jaw gripping battery gets between the cold pressing plate, and battery is carried out cooling and shaping.
