Description
Technical field
The relevant a kind of electric energy feeding unit of the present invention is applied to the power supply of various electronic installations, refers to that especially a kind of tool can bear the ceramic separator of high temperature and keeps electronic isolation and increase the electric energy feeding unit of ionic conductance.
Background technology
Separator (film) is played the part of critical role in lithium battery, it produces the contact of physical property to prevent electrode between the positive and negative electrode layer, and it allows free ion therebetween to pass through, and electronics is completely cut off to prevent then that short circuit from taking place.It must for electrolyte or electrode material has chemistry and electrochemical stability; And must have certain mechanical strength, can stand the high-tension intensity of battery in assembling process, and keep the spacing between the layer of the two poles of the earth.With regard on the structure, separator need have enough porositys and come Electolyte-absorptive, to keep higher ionic conductance (Ionic Conductivity).Yet separator can increase electronic impedance, and occupies the factor that available space in the battery etc. is unfavorable for the battery performance; Therefore, important role is being played the part of in the battery performance last (as energy density, power density, circulation usefulness and fail safe etc.) that is chosen in of separator.
Present commercial separator material mostly is polyolefin (Polyolefin), be main as polyethylene (PE) or polypropylene (PP), yet the fusing point of PE is about 130 ° of C, and the fusing point of PP is about 160 ° of C, when internal temperature of battery exceeds the fusing point of material, separator (film) can the fusing contraction cause the pole plate contact short circuit, causes the very exothermic reaction between utmost point layer and electrolyte simultaneously, causes battery explosion.Therefore, developed towards the separator (film) of ceramic material one after another in recent years, relied on for counsel the characteristic of the preferable high temperature resistant and wetability of ceramic material.
Mainly contain two kinds of kenels in the practical application, at first first type announces the 5th, 342 as United States Patent (USP), and No. 709 patents are to be the ceramic separator of main material with the ceramic particle directly, replace known polyolefinic separator; On the other hand, the part of second type discloses patent No. 2008/0138700 as U.S. patent application case, is earlier ceramic particle to be coated on the films such as PET, PEN, PI and formed ceramic separator.Yet, no matter the ceramic separator of above-mentioned any kenel all faces the disappearance that is difficult to overcome.
Be example with first type at first, from processing procedure, system is attached to ceramic particle on the utmost point layer by solid, because of the solid system of solid system (binder system) and utmost point layer close, so solvent (solvent) system also can be close, after coating during solvent evaporated, can between interface, arrange reformation because the solid system is close, the generation phenomenon of entwining, and form the interface hole, and these a little holes will be good ion channels, but because solvent evaporate to dryness in the short time, be easy to differ because of evaporate to dryness speed, and produce bigger hole (bigger through hole) in zone partly, and and cause the micro-short circuit phenomenon, make the electronic isolation reduction of battery; Therefore, because this Interface status is difficult to effective control, so short circuit ratio is difficult to effective reduction always.
Moreover, be example with above-mentioned second type, present modal solid has poly-difluoroethylene (Polyvinylidene fluoride; PVDF), polyvinylidene fluoride-altogether-trichloroethylene (PVDF-HFP), yet no matter be PVDF or PVDF-HEP, its with films such as PET, PEN, PI to follow effect not good, ceramic particle is easy to peel off can't film forming; Moreover, have hole on the films such as the PET of this kenel, PEN, PI for ion conducting (it is more to be generally through hole), and then coat by ceramic separator and to finish electronic isolation on it, so general thickness can be thinner compared to first type.Same, because speed inequality during solvent seasoning probably can produce than macroscopic void, influence the characteristic of its electronic isolation; If increase electronic isolation, then the proportion of adhesive agent must be improved, in case but proportion improves, can influence ionic conductance again, be difficult to effectively average out a little; Moreover, increasing ionic conductance if will improve the amount of ceramic particle, the amount that certainly will also must increase solid synchronously can effectively be sticked together, and the content proportion of therefore general ceramic particle can't improve, and the highest only being about about 40% is so whole thermal endurance is relatively poor; Simultaneously, ionic conductance is also relatively poor.In order to solve the problem of this ionic conductance, known also have in adhesive agent, to increase plastic agent or the solution of non-solvent are arranged, recycling physics or the mode of chemistry are removed after forming barrier film, pass through for ion and can keep hole in barrier film, to increase ionic conductance.
Simultaneously, because of the general property of water-bearing height of ceramic particle, in the time of removing this adsorbed water, temperature must be heated to 190 ° more than the C at least, but the fusing point of general solid is not high, such as PVDF is about 170 ° of C, PVDF-HEP and is about 120-150 ° of C; Therefore, anhydrate more than the C in case be heated to 190 °, then solid can melt, and makes ceramic separator inside holes distribution to change, and makes electric charge shift variation, and influences the performance of battery.And if with the formed hole of modes such as above-mentioned plastic agent, then also can melt because of solid, hole is filled up, make ionic conductance effectively to promote.Moreover, if in operating process, reach this condition of high temperature, then will make solid fusing, separator disintegration, make that battery is short-circuited, the problem of fail safes such as fault or blast.
On the other hand, if adopt the higher macromolecule of thermal endurance fully, be epoxy resin (Epoxy), acryl resin (Acrylic Acid), polyacrylonitrile (polyacrylonitrile for example; PAN) etc., its tackness is good and also can be high temperature resistant, builds bridge (cross-linking) yet its structure is network type, and the hole in the structure distributes and is unfavorable for that ion passes through, and makes the ionic conductance variation, and is difficult to be applied in the battery unit.So because of above-mentioned variety of problems, present ceramic separator quite is difficult to be applied to industry, just it is arranged on utmost point layer or the separator in the film mode mostly.
Because above-mentioned, the present invention satisfies the disappearance at above-mentioned known techniques, proposes a kind of electric energy feeding unit and ceramic separator thereof, effectively to overcome these above-mentioned problems.

Embodiment
For the clear disclosed electric energy feeding unit of the present invention and the ceramic separator thereof of disclosing, several embodiment below will be proposed to describe technical characterictic of the present invention in detail, help more simultaneously with accompanying drawing those technical characterictics are shown.
Please refer to shown in Figure 1A and Figure 1B, it is the structural profile schematic diagram of the electric energy feeding unit of preferred embodiment of the present invention.Electric energy feeding unit 3 comprises ceramic separator 31, first electrode base board 32 and second electrode base board 33, first electrode base board 32 comprises first current collection layer 321 and first active material layer 322, first current collection layer 321 has the first relative side 323 and second side 324, and first active material layer 322 is located at first side 323 of first current collection layer 321.Second electrode base board 33 comprises second current collection layer 331 and second active material layer, 332, the second current collection layers 331 and has first side 333 that the first relative side 333 and second side, 334, the second active material layers 332 are located at second current collection layer 331.
Because adopting ceramic particle as main body, so the structural strength height of bulk ceramics separator 31, be enough to support first circuit substrate 32 with and/or second circuit substrate 33, and also have the effect of electronic isolation, prevent the electronic conduction of both sides.Moreover, because adopt two solid systems, include linear polymeric and bridge formation macromolecule simultaneously, by the higher adhesive properties of bridge formation macromolecule, cooperate linear high molecular collocation, make that stick together structure is unlikely the too high and easy fracture of rigidity, what first electrode base board 32 of both sides and second electrode base board 33 can be sticked together is quite firm, keeps stability and the fail safe of electric energy feeding unit 3; Simultaneously, also because the characteristic of this pair solid system, compared to known employing single linear macromolecule as solid, the proportion of ceramic particle can be drawn high, even surpass more than 60% or 90%, make that thermal endurance and the thermal stability of bulk ceramics separator are better, and ceramic particle accounts for ceramic insulation stratum proportion and improves, piled up the hole that produces by ceramic particle because big multiple hole is many, so distributing, hole becomes good, while is owing to macromolecule content descends, and the obstacle that consequent interference ion moves also reduces simultaneously, and makes ionic conductance improve.
And the high molecular part of building bridge, it can be epoxy resin (Epoxy), acryl resin (Acrylic Acid), polyacrylonitrile (polyacrylonitrile; PAN) and the network type bridge formation macromolecule of combinations thereof, because the formed bridge formation structure of these a little bridge formation macromolecules is network-like (network), overall structure is comparatively closely knit, after cooperating linear polymeric, hole distributes can be unfavorable for that still ion passes through, increase the solid interference that ion moves simultaneously, therefore, ionic conductance still can be worse than general barrier film slightly; But also because of above-mentioned reason, the chance and the ratio that make the medium-and-large-sized through hole of ceramic separator exist descend because network type builds bridge high molecular existence, and then electronic isolation is increased.Therefore, the high molecular part of building bridge also can adopt such as for polyimides (polyimide; PI) and the scalariform of derivative (ladder) bridge formation macromolecule, be different from aforementioned network formula bridge formation structure, trapezoidal linear strands bridge construction, will make the hole distribution in the ceramic separator 31 be fit to very much the ion conducting, simultaneously because non-network type bridge formation structure, the interference of moving for ion descends a lot of, even the hole distribution than uses linear polymeric better as adhesive agent merely, therefore ionic conductance can significantly improve, not only can be applied to electrical energy supply system 3, while is compared to the ionic conductance of general barrier film, also increase to some extent, simultaneously, the macromolecule of this ladder type frame bridge construction (PI) can be possessed quite high electronic isolation characteristic again, makes ceramic separator obtain best balance point; On the other hand, because adopting two solid systems, when also making ceramic separator 31 be formed on the utmost point layer, behind mature making process, the bridge formation macromolecular structure can reduce on the interface possibility that generation forms than macroscopic void when removing solvent, keeping effective electronic isolation characteristic, and reduction micro-short circuit rate.Moreover, because the high molecular thermal stability of building bridge is quite high, high temperature in the time of can bearing ceramic particle and add the heat abstraction adsorbed water and not melting, also can stand for the heating in the electric energy feeding unit 3 charge/discharge processes simultaneously, keep the relative position between first electrode base board 32 and second electrode base board 33 under the condition of high temperature, and then keep stability and the fail safe of electric energy feeding unit 3.
Wherein, with the enforcement aspect of Fig. 1 B, for the ion that makes two side pole layers can give conducting, first current collection layer 321 and second current collection layer 331 have a plurality of micropores hole 3213,3313.And first active material layer 322 and second active material layer 332 more can have electrolyte distribution in wherein, and it can be liquid electrolyte, colloidal electrolyte or solid electrolyte; Simultaneously, because the adhesional wetting of ceramic material (wettability) is preferable, for electrolytical distribution the bonus point effect is also arranged.
See also Fig. 2, be another embodiment schematic diagram of electric energy feeding unit of the present invention.The enforcement aspect of itself and above-mentioned Figure 1B is approximate, and ceramic separator 31 replaces with substrate 20, and has the micropore hole 21 corresponding to a plurality of micropores hole 3213,3313 of first current collection layer 321 and second current collection layer 331 on the substrate 20; Because first current collection layer 321, substrate 20 and second current collection layer 331 have corresponding micropore hole 3213,21,3313, therefore be all conducting state basically, electrolyte can be easily evenly infiltrates second active material layers 332 by first active material layer 322, time that need not overspending.
Above-mentioned enforcement aspect, basically be similar to the aspect of the first known type, certainly, see also shown in Figure 3, also can be applicable to the aspect of second type, have additional isolated film 41 in ceramic separator 31 1 sides, the material of isolated film 41 can be pi (PI), PETG (PET), PEN (PEN), glass fibre or liquid crystal type macromolecule.Simultaneously, isolated film 41 also can be extended (seeing Fig. 4 A) towards a direction, for electronic building brick 42 arrange, carrying, then by encapsulating structure or the mode of all the other electric connections is connected.Moreover an other side of isolated film 41 can also include another ceramic separator 31'(and see Fig. 4 B).
The encapsulation of above-mentioned electric energy feeding unit 3 can be encapsulated by known mode, is not given unnecessary details at this.
Comprehensively above-mentioned, the disclosed electric energy feeding unit of the present invention system utilizes ceramic particle and pair formed ceramic separator of solid systems to reach electrical isolation and ion conducting.By the characteristic of ceramic particle and two solid system, and can provide suitable high-fire resistance, therefore can keep the relative position (especially under the high temperature) of two side pole layers, guarantee the stability, fail safe of electric energy feeding unit and electrically.In addition on the one hand, because bridge formation macromolecule, the especially PI of scalariform bridge formation structure, make the very suitable ion of hole distribution in the ceramic separator pass through, therefore be that the separator of base material can't reach the awkward situation that ionic conductance requires except overcoming known pottery, more can be under the situation of keeping electronic isolation, significantly improve ionic conductance, obtain the optimum balance of electronic isolation and ionic conductivity, and then the usefulness of electrical energy supply system is significantly promoted.
