Definitions
- the invention relates to an electrode of an electrochemical arrangement containing lithium as the active material, in particular a Li battery or a Li capacitor, consisting of at least one electrically well-structured, structured carrier layer and an electrically conductively connected layer of electroactive material, which is used for solid bodies -Ion exchange reactions experience relatively large volume changes.
- a Li battery or a Li capacitor consisting of at least one electrically well-structured, structured carrier layer and an electrically conductively connected layer of electroactive material, which is used for solid bodies -Ion exchange reactions experience relatively large volume changes.
- Electrodes of the type mentioned such as, for example, lithium-ion batteries, lithium batteries, lithium-polymer batteries and the like, generally consist, among other things, of one or more electrodes, which in turn are a combination of electroactive material - and optionally various additives - are constructed with an electrical conductor.
- the actual conductor in this composite consists, for example, of an etched or perforated metal foil, one of the type of. Expanded metal produced metal foil, a mesh-like metal grid, or the like. Examples of this can be found, for example, in US 6,103,416 A, US 4,794,060 A or also EP 1 033 767 A1.
- the object of the present invention is to improve an electrode of the type mentioned at the outset in such a way that the disadvantages of the known arrangements are avoided and, in particular, that the relatively large changes in volume of the electroactive material in the ion exchange reactions are compensated for in a simple manner and thus the service life is extended the overall arrangement is possible with a consistently good usable energy density.
- the carrier layer consists of a three-dimensional fabric made of electrically conductive flexible threads which are coated with the electroactive material at least in regions over at least a large part of the fabric thickness.
- Such fabrics can be made in the manner of fabrics in a known manner very simply using weaving or knitting technology, it being fundamentally irrelevant whether the lattice structure is first woven or knitted, for example, from non-conductive plastic threads and then made suitable in a suitable manner overall is, or whether the weaving or knitting is done with previously conductive threads or threads previously made separately conductive.
- the production of the three-dimensional fabric by weaving (from at least two (warp and weft) or even several threads) or by knitting (knitting, crocheting, bobbin lace - from one thread) is completely equivalent for the purposes of the present invention - any other could other suitable methods for producing such three-dimensional lattice structures are used.
- the resulting flexible lattice or its thread structure is according to the invention then at least in some areas (but could also be continuous overall) coated with the electroactive material.
- the generally flexible three-dimensional lattice work can compensate for this relatively generously locally by warping the individual lattice threads, without mechanical stresses that cannot be controlled over large areas and the associated separations of electroactive material would be feared.
- volume changes of up to about 259% must be expected or countered accordingly.
- the gradual loss of charge capacity with each charge cycle that has hitherto been associated with such materials can be kept very simple in the manner described, the three-dimensional lattice work additionally giving the advantage of stable arrangements with high energy density.
- the carrier layer has locally different weave densities, which offers a wide variety of options for influencing the design of the overall arrangement. For example, increased conductivity and mechanical stability can be provided in a denser woven area or in a denser layer, whereas more electroactive material is arranged on the flexible threads in looser or woven areas with greater grid spacings, or the penetrability of the structure for the electrolyte or additives can be improved.
- the different current densities prevailing in different areas of the electrochemical arrangement can also be better taken into account via different weave densities.
- the backing layer is multilayer, with at least one relatively dense and at least one relatively loosely woven layer, with which the functional division already mentioned above is divided into a stable, highly conductive and a flexible, relatively much electroactive material-carrying layer is easily achieved.
- At least one of the layers can have a woven-in pattern with a weaving density that increases at least in some areas towards the external connection of the electrode, which offers the advantages already mentioned above with regard to taking account of locally different current densities.
- the backing layer as a whole consists of a three-dimensionally woven polymer material woven at least in part and / or locally different weave density, at least partially composed of electrically conductive coated fibers, preferably of monofilament or very long individual threads and without ends protruding from the fabric.
- the thickness of the interwoven threads is in the range from 0.05 to 1.0 mm, which makes it possible to cover a wide variety of requirements for such arrangements with corresponding electrode designs.
- non-conductive threads for example the polymer fibers mentioned, these can be provided in a preferred further embodiment of the invention with a continuous coating of 0.01 to 10 ⁇ m thickness of a metal Group Cu, Fe, Ti, Ni, Cr, Al, Ag, Au, Mn, stainless steel or their alloys or with other conductive substances, such as electrically conductive oxides, conductive carbon black or the like, can be coated in various known suitable ways, wherein it can additionally be provided that this continuous conductive coating with a second continuous coating from the group of the following metals or their alloys: Cu, Fe, Ti, Ni, Cr, Al, Ag, Au, Mn and stainless steel, or with conductive oxides or Carbon black is coated, the total thickness of both layers not exceeding 15 ⁇ m. With these configurations, the most varied areas of application of such electrodes or materials used can be covered.
- the plastic woven threads can consist of fibers of a polymer from the following group: polyester, silicone rubbers, polyethylene, polypropylene, ethylene-tetrafluoroethylene copolymer, poly-tetrafluoroethylene and polyvinylidene fluoride.
- independent metallic threads preferably made of a metal from the group Cu, Fe, Ti, Ni, Cr, Al, Ag, Au, Mn, stainless steel or their alloys, can be woven into the carrier layer at regular intervals, preferably with a diameter, which corresponds in size to the diameter of the conductively coated fibers.
- the conductivity in the three-dimensional grid of the electrode can, if necessary, be further influenced locally and adapted to the respective requirements, it usually being possible to find sufficiency with a relatively small percentage of such continuously conductive threads in order not to unnecessarily increase the total weight of the electrode increase.
- FIG. 1 shows a detail from an electrode according to the invention with a region-wise coating of a plastic thread made superficially conductive with electroactive material
- FIG. 2 shows the effects of volume changes of the electroactive coating according to FIG. 1 in the case of ion exchange reactions
- FIG. 3 shows one of the 1 corresponding detail with a continuous coating with electroactive material over a larger area
- FIG. 4 shows a schematic view of a part of an electrode according to the invention with two areas of locally different weave density of the carrier layer
- FIG. 5 shows the arrangement according to FIG. 4 during volume changes during Ion exchange reactions
- FIGS. 6 to 8 show examples of carrier layers of electrodes made up of several layers with locally different weave densities according to the present invention.
- FIGS. 1 to 3 each show a region of a thread 1 made of a three-dimensional fabric 2 (see also FIGS. 4 to 8), which forms the carrier layer 3 of the electrode of an electrochemical arrangement, which electrode is not shown in further detail.
- the threads 1 are coated according to FIGS. 1 to 3 with a continuous coating 4 made of conductive material, such as copper, iron, stainless steel, conductive carbon black or the like, and are themselves preferably made of polymer - apart from that, individual or all of the threads could 1 also consist of self-conductive material or other conductive coated materials.
- the carrier layer 3 of the electrode which consists of the three-dimensional fabric 2 made of electrically conductive, flexible threads 1, is at least partially covered over at least some areas of the fabric thickness 5 indicated in FIGS.
- electroactive material 6 which undergoes relatively large volume changes in ion exchange reactions, for example with the electroactive substances commonly used in lithium-ion batteries, lithium batteries, lithium polymer batteries and similar arrangements, such as about Sn.
- electroactive substances commonly used in lithium-ion batteries, lithium batteries, lithium polymer batteries and similar arrangements, such as about Sn.
- aluminum such metals and alloys have so far been practically not used in corresponding arrangements, since they tend to mechanically separate from their base due to the large volume changes when Li + (or the like) ions are taken up or released, which is the case with batteries, for example a gradual loss of charge capacity with each charge cycle.
- the backing layer 3 has a locally different weave density of the three-dimensional fabric 2 on which it is based, with the backing layer 3 having multiple layers in at least one embodiment, with at least one relatively densely (9) and at least one relatively loosely woven layer (8) is trained.
- the more densely woven layer 9 can increasingly take on the tasks of lossless power conduction and a relatively high mechanical stability, while the loosely woven layers offer more space for the electroactive material or the electrolyte and other substances.
- the more densely woven layer 9 has a woven-in pattern with a weaving density increasing at least in regions towards the external connection (10) of the electrode, which takes into account the fact that the current density also increases towards this connection.
- Such patterns can be produced very easily in the woven or knitted grid of the carrier layer on looms or similar devices.
- monofilament or very long individual threads are preferably used to produce the fabric, since ends protruding from the fabric (as for example in the case of felt) increase the risk of short-circuiting in the overall arrangement.
