Definitions
- the secondary battery contains a cathode, an anode and an electrolyte which is arranged between the cathode and anode and has an alkali metal-ion-conductive contact to the cathode and to the carbon layer of the anode.
- the anode contains or consists of a carbon layer, wherein the carbon layer alone or in combination with an electrically conductive substrate forms an electrically conductive contact.
- the secondary battery is characterized in that the carbon layer contains pores of a first type, which are not accessible to the electrolyte and which are suitable for receiving electrochemically deposited alkali metal in metallic form during a charging process of the alkali metal secondary battery.
- the alkali metal secondary battery is characterized by a very high specific capacity, high power density, high cycle stability, high long-term stability and high operational reliability.
- Increasing the energy density of battery cells is a global goal of research and development, among other things to increase the range of electric vehicles.
- the focus is on solid-state batteries, as it is expected that the solid-state electrolytes allow the safe and stable operation of metallic lithium anodes and thus the thicker and heavier graphite anodes can be replaced.
- an alkali metal secondary battery which is characterized by a high specific capacity, a high power density and high cycle stability and the lowest possible mechanical loads act on the components of the secondary battery during their operation, so that whose long-term stability and operational safety are increased.
- the object is achieved by the lithium secondary battery with the Merkma len of claim 1 and the use according to claim 16.
- the dependent claims show advantageous developments.
- an alkali metal secondary battery containing it a) a cathode
- an anode that contains or consists of a carbon layer, where the carbon layer alone or in combination with an electrically conductive substrate forms an electrically conductive contact;
- an electrolyte which is arranged between the cathode and anode and has an alkali metal ion-conductive contact to the cathode and to the carbon layer of the anode;
- the carbon layer contains pores of a first type which are not accessible to the electrolyte and which are suitable for receiving electrochemically deposited alkali metal in metallic form during a charging process of the alkali metal secondary battery.
- carbon layer means in particular a layer which consists of electrically conductive carbon materials selected from the group consisting of porous carbon, carbon black, graphene, graphite, graphite-like carbon (GLC), carbon fibers, carbon nanofibers, Carbon hollow spheres and mixtures or combinations thereof.
- electrically conductive carbon materials selected from the group consisting of porous carbon, carbon black, graphene, graphite, graphite-like carbon (GLC), carbon fibers, carbon nanofibers, Carbon hollow spheres and mixtures or combinations thereof.
- the preferred specific features of the "carbon layer” eg pore volume, specific density, pore size etc.
- this carbon layer can of course contain other substances (eg binder and / or alkali metal) If, for example, the carbon layer contains other substances (for example, in its pores of the second type), the specific characteristics may differ from the ranges given here.
- the alkali metal secondary battery has the advantage that it is not only characterized by a very high specific capacity and a high power density, but also that the components of the secondary battery are subjected to very little mechanical stress during operation, so that the alkali metal secondary battery has high long-term stability and has a high level of operational reliability.
- the pores of the first type allow efficient and reversible uptake of deposited metallic alkali metal. What is important here is the fact that the electrolyte of the secondary battery cannot penetrate into the pores of the first type.
- the provided alkali metal secondary battery goes back to a surprising discovery: It is known that during the discharge process of an alkali metal secondary battery, metallic alkali metal is oxidized to alkali metal ions by releasing electrons. Theoretically, the resulting alkali metal ions can only be efficiently absorbed and diverted by the electrolyte if it is in direct contact with the alkali metal ions. In other words, in the event of a loss of contact between the resulting alkali metal ions and the electrolyte, the transport of alkali metal ions to the electrolyte should become very inefficient or even break off. However, the applicant has surprisingly found that this is not the case when the carbon layer described above is used.
- alkali metal ions that are removed to the electrolyte within the pores of the first type are efficiently passed on to the electrolyte via the carbon structure (in particular within the pores of the first type) and do not - as expected - lead to a break in the charge transport comes.
- the alkali metal secondary battery can be characterized in that the pores of the first type are provided with a chemical modification which favors an absorption of metallic alkali metal produced by deposition.
- the chemical modification is preferably selected from the group consisting of a layer on the pore surface, nanoparticles on the pore surface, at least one chemical functional group on the pore surface and combinations thereof.
- the pores of the first type can have a specific pore geometry and / or pore nature. The formation of metallic structures in the pores of the first type can be promoted by the pore geometry and / or the pore nature. The over potential (the energy barrier) for the separation of alkali metal from the electrolyte can thus be reduced.
- the pores of the first type can have a pore size in the range from 0.5 to 100 nm. Furthermore, the pores of the first type can have a pore size of> 2 nm. The pores of the first type particularly preferably have a pore size of ⁇ 2 nm, because in this case the formation of metallic Li clusters could be observed above 0 V (vs. Li / Li +), which indicates a lowering of the thermodynamic enthalpy of formation (see example) where the pore size can preferably be determined with nitrogen physisorption.
- the carbon layer can also contain pores of a second type and / or cavities that are accessible to the electrolyte.
- the pores of the second type provide a large contact area for the electrolyte, so that an effective transport of alkali metal ions from the electrolyte to the carbon layer and back is possible and thus high charging and discharging currents with excellent reversibility (cycle stability) are achieved.
- the electrolyte can penetrate deep into the carbon layer via the pores of the second type and thus a deposition of metallic alkali metal can also take place in deeper layers of the carbon layer of the anode, i.e. in a certain way via a deep, "three-dimensional" interface with an enlarged surface compared to a "two-dimensional” interface that does not go deep.
- the pores of the first type also serve as "free spaces" in the deep layers of the carbon layer for the absorption of deposited, metallic alkali metal, since these pores are not filled with electrolyte.
- the alkali metal secondary battery according to the invention thus has a higher long-term stability and operational reliability than known alkali metal secondary batteries.
- the "three-dimensional” interface advantageously provides a contact surface to the electrolyte that is 2 to ⁇ 100 times as large, preferably 3 to 30 times as large, particularly preferably 5 approx . 20 times as large, in particular 8 to 12 times as large as the "two-dimensional" contact surface to the electrical rolytes.
- a higher “three-dimensional” contact surface for example in the range 100-1000 times as large, would in turn be disadvantageous, since losses due to secondary reactions also occur at the interface between carbon layer and electrolyte and these become disadvantageous if the contact surface is too large.
- the pores of the second type and / or the cavities can have a spatial expansion in all three spatial directions which is in the micrometer range, in particular in the range from 1 ⁇ m to 1000 ⁇ m, the spatial expansion preferably being determinable with electron microscopy.
- the pores of the second type and / or the cavities contain electrolyte, preferably in an entire volume of their spatial extent.
- the carbon layer can contain an alkali metal, preferably lithium or sodium, the alkali metal preferably being contained in a proportion of 10 to 90% by weight, based on the total weight of the carbon layer.
- the carbon layer cannot contain any lithium or sodium, preferably no alkali metal, in an uncharged state.
- the electrolyte is a sulfidic solid electrolyte.
- the electrolyte can, however, also be a liquid electrolyte or gel electrolyte and all components of the electrolyte, in particular all molecules of the electrolyte, can have a size which exceeds the size of the pores of the first type and / or exceeds the size of pores of a protective layer between the electrolyte and the porous carbon particles is angeord net, wherein the protective layer is conductive for alkali metal ions.
- the electrolyte preferably contains or consists of an ionic liquid.
- the carbon layer forms a carbon structure that is suitable for transporting alkali metal ions along the carbon structure.
- the pores of the first type are suitable for transporting alkali metal ions within the pores of the first type (for example along the pore walls).
- the alkali metal secondary battery When the alkali metal secondary battery is discharged, there is inevitably a certain distance between the alkali metal deposited in the pores and the electrolyte, which, depending on the pore size, can be several 100 nm.
- a complete return transport of the alkali metal stored in the pores or, after their oxidation, the alkali metal ions stored there in the electrolyte is necessary.
- Such a complete return transport can only follow if the carbon structure, especially the pores of the first type, is / are suitable for guiding the alkali metal ions to the electrolyte.
- the pores of the first preferably have these properties, since this increases the discharge capacity of the secondary battery.
- the pores of the first type of carbon layer can together have a pore volume of> 0.5 cm 3 / g carbon, preferably> 0.8 cm 3 / g carbon, particularly preferably> 1.0 cm 3 / g carbon.
- a high pore volume has the advantage that a large space is provided for accommodating metallic alkali metal produced by deposition, which provides high capacities and the contact area with the electrolyte is maximized, which ensures high charging and discharging currents.
- a large pore volume means that the weight of the secondary battery can be kept low, which is a decisive advantage especially for mobile applications (lower power to weight ratio).
- the carbon layer can have micropores, mesopores and / or macropores classified according to IUPAC, preferably have micropores classified according to IUPAC.
- the carbon layer can be suitable for absorbing metallic alkali metal produced by deposition in an amount such that the carbon layer has a specific capacity of> 400 mAh / g, preferably> 600 mAh / g, particularly preferably> 800 mAh / g, in particular> 1000 mAh / g, based on the mass of the carbon material.
- the electrolyte can have an ionic conductivity s of at least 10 10 S-cm 1 , preferably at least 10 ⁇ 8 S-cm 1 , particularly preferably at least 10 6 S-cm 1 , very particularly preferably at least 10 4 S-cm 1 , in particular at least 10 3 S-cm 1 .
- the electrolyte has a lower conductivity for electrons than the electrically conductive substrate or the carbon layer of the anode and / or than the cathode, preferably it has essentially no conductivity for electrons.
- the electrolyte can be designed as a foil.
- the electrolyte from the anode in the direction of the cathode can have a maximum expansion in a range from 1 miti to 100 miti, preferably 10 miti to 50 miti.
- the cathode can contain a current collector, the current collector preferably being designed in the form of a layer, the layer being particularly preferably designed as a stretch layer, layer with double-sided coating, layer of fiber fabric, layer with primer layer.
- the cathode can contain no alkali metal source or contain an alkali metal source, the alkali metal source preferably being present in a proportion of 60 to 99% by weight, based on the total weight of the cathode.
- the cathode can contain a solid electrolyte.
- the cathode can contain an electrically conductive conductive additive.
- the cathode can contain at least partially fibrillar polytetrafluoroethylene, the at least partially fibrillar polytetrafluoroethylene preferably being contained in a proportion of ⁇ 1% by weight, based on the total weight of the cathode.
- the cathode consists of the components mentioned above.
- the alkali metal secondary battery may be a lithium secondary battery or a sodium secondary battery.
- the alkali metal secondary battery according to the invention for a means of transport, a building and / or an electronic device, preferably as an energy source for a means of transport selected from the group consisting of automobiles, aircraft, drones, trains and combinations thereof.
- FIG. 1A-C show schematically the processes at the interface between a carbon particle 6 of the carbon layer of the anode and the electrolyte 8 of the alkali metal secondary battery of the invention, which is a lithium secondary battery here.
- the charging process shown in FIG. 1A lithium ions are transported from the cathode (not shown) through the electrolyte 8 into a pore 7 of the first type of the carbon particle 6. There the lithium ions take up electrons which are released from the conductive layer of the anode (not shown) to the carbon particles 6 flow, and are reduced to lithium metal 10, which is now located within the pores 7 of the first type.
- FIG. 1A-C show schematically the processes at the interface between a carbon particle 6 of the carbon layer of the anode and the electrolyte 8 of the alkali metal secondary battery of the invention, which is a lithium secondary battery here.
- the metallic lithium 10 is oxidized to lithium ions by withdrawing electrons (ie metallic lithium is dissolved) and the lithium ions can be absorbed by the electrolyte and transported to the cathode.
- the situation shown in FIG. 1C describes the surprising discovery that even lithium metal 10, which is dissolved to lithium ions far away from the electrolyte 8, is still efficiently transported to the electrolyte 8 and from there to the cathode. An efficient transport of lithium ions along the pore 7 of the first type in the direction of the electrolyte 8 must therefore be possible.
- 2A-B show schematically the structure of an alkali metal secondary battery according to the invention.
- the alkali metal secondary battery shown contains a cathode 1 and an anode 2, which contains an electrically conductive substrate 3, where the electrically conductive substrate 3 extends over a certain geometrical area 4 and on this area 4 at least partially a carbon layer 5 is arranged, wherein the carbon layer 5 contains carbon particles 6 which have pores 7 of the first type and form an electrically conductive contact with the electrically conductive substrate 3 of the anode 2 and with one another.
- the secondary battery also contains an electrolyte 8, which is arranged between the cathode 1 and anode 2 and has an alkali metal-ion-conductive contact with the cathode 1 and with the carbon particles 6 of the anode 2.
- the carbon layer 5 has between the carbon particles 6 pores 9 of the second type, which at least partially contain the electrolyte 8, the pores 7 of the first type having such a small pore size that they are unsuitable for receiving the electrolyte and are suitable for this to pick up metallic alkali metal 10 generated by deposition.
