To use cathode material advantageously in a high-current cell or a high-current battery. In addition, in such a cell or battery can be dispensed with an introduction of liquid electrolyte into the cathode and in particular the cell can be provided as a solid-state cell. An alkali metal cell may in particular be understood to mean an electrochemical cell, for example a battery cell or accumulator cell, to whose electrochemical reaction alkali ions, for example lithium ions, for example in the case of a lithium cell, or sodium ions, for example in the case of a sodium cell, are involved , For example, an alkali metal cell may be a lithium cell and / or a sodium cell.

For example, an alkali metal sulfur cell may be a lithium sulfur cell and / or sodium sulfur cell. A polymer electrolyte may, in particular, be understood as meaning an ion-conducting or ion-conducting, for example, lithium ion-conducting or lithium ion-conducting polymer. For example, therefore, an ion-conducting or ion-conducting, for example, lithium ion-conducting or lithium ion-conducting, polymer may also be referred to as a polymer electrolyte. When used in a cathode material, a polymer electrolyte may also be referred to as cathode electrolyte or catholyte in particular. For example, the polymer electrolyte may be lithium ion conductive or lithium ion conductive and / or sodium ion conductive or sodium ion conductive, in particular

Cyclized polyacrylonitrile (cPAN) may in particular have a structure of interconnected, in particular fused, rings, in particular six-membered rings, and / or a repeating unit comprising three carbon atoms and one nitrogen atom, for example, wherein adjacent rings have at least two common carbon atoms. By means of sulfur-polymer composites, improved binding and / or finely distributed embedding of the sulfur, as well as improved mechanical properties, can advantageously be achieved compared with sulfur-carbon modification composites, whereby the electrical and / or ionic contacting and sulfur utilization are achieved and thus the energy density can be improved.

For example, the at least one cathode active material or the sulfur-polymer composite may comprise or be a polymer having, for example, partially or completely, for example, covalently and / or ionically, in particular covalently, bound sulfur.

In particular, nitrile groups can thereby react to form a polymer, in particular with a conjugated ττ system, in which the nitrile groups are converted to nitrogen-containing rings, in particular six-membered rings, in particular with covalently bonded sulfur, which are attached to one another. For example, SPAN can be prepared by heating polyacrylonitrile (PAN) with an excess of elemental sulfur, especially at a temperature of> 300 ° C, for example, about> 300 ° C to <600 ° C.

The polymer backings of the polymer, in particular covalently bonded sulfur, and the polymer backings, for example the polymer backbone-forming unit [A], of the at least one polymer electrolyte can thereby in particular, form a structural plane. As a result of the fact that the polymer with, in particular, covalently bonded sulfur can already provide mechanical stability, the at least one polymer electrolyte can advantageously be simple, for example, only with ion-conducting or ion-conducting, in particular lithium ion-conducting and / or lithium ion-conducting,

Composite bound sulfur, for example sulfur-polyacrylonitrile composites, in particular SPAN, can have a particularly advantageous effect. In addition, polymers which have a negatively charged group Q ^" and a counterion Z ⁺ , for example a lithium ion Li ⁺ and / or a sodium ion Na ⁺ , in particular a lithium ion Li ⁺ , already have a sufficient ionic conductivity, in particular lithium ion conductivity, due to the counterion Z ⁺ Thus, polymers having a negatively charged group Q ^" and a counterion Z ⁺ , for example a lithium ion Li ⁺ and / or a sodium ion Na ⁺ , in particular a lithium ion Li ⁺ , can be present without the addition of an alkali metal conducting salt, for example lithium Conducting salt, be used or ion-conducting, in particular lithium ion-conducting be.

In the context of one, in particular alternative or additional, embodiment of this embodiment, Q stands for a positively charged group Q ⁺ , for example a positively charged side group Q ⁺ , and a counterion Z ^" .

In particular, the positively charged group Q ^{+ can} be attached via the spacer X to the polymer backbone-forming unit - [A] -. In this case, the positively charged group Q ⁺ may stand, for example, for a group based on a cation of an ionic liquid (English: lonic liquid). In particular, a counterion can be used as the counterion to the positive charge of Q ⁺

or anion Z ^"be included. As the counter ion ^Z" may, for example, such as all common counter ions known conductive salts are, for example, for lithium cells used. In particular, therefore, Z ^" can be an anion, in particular a lead salt anion, and in particular anions of conducting salts, in particular lithium, can be formed by a positively charged group Q ^+. Leitsalzanionen, coordinated or solvated and in particular the dissociation of the conducting salt, in particular lithium-Leitsalzes be increased. As a result, in turn, advantageously, the transfer number, in particular by the covalent attachment of the positively charged group Q ⁺ to the polymer back-forming unit - [A] -, and optionally the mobility of

Alkali ions, in particular lithium ions, of the conductive salt and thus the

ion conductivity, in particular the lithium-ion conductivity can be increased. In addition, advantageously, the dielectric constant can be increased, which can have a positive influence on the polysulfide solubility - in such a way that the polysulfide solubility is reduced - which is particularly in sulfur-carbon composites, for example, sulfur polymer and / or Carbon-modification composites, in particular sulfur-polymer composites with, for example, covalently and / or ionically,

especially covalently bound to the polymer of the composite sulfur, for example sulfur-polyacrylonitrile composites, such as SPAN, can particularly advantageous effect. The polymer back-forming unit - [A] - and / or the spacer X can also optionally be optimized with regard to other properties. In particular, polymers having a positively charged group Q ^{+ may be used} in combination, for example, in U.S. Pat

Electrolytic solvent derivable group stand. By means of an uncharged group Q, alkali metal ions, for example lithium ions, can advantageously be coordinated or solvated. Thus, advantageously, the mobility of the alkali ions, for example lithium ions, in particular by introducing the derivable from an electrolyte solvent group, and thus the ion conductivity, in particular lithium ion conductivity, can be increased. The polymer back-forming unit - [A] - and / or the spacer X can be optionally optimized with regard to other properties. Polymers which carry only uncharged groups Q, and in particular no bonded charges, for example alkali ions, in particular lithium ions, may initially be only ionically conductive, for example lithium ion conductive, and for example by addition of an alkali metal salt, for example alkali metal conducting salt, in particular lithium salt, for example by a mixture with an alkali metal salt, for example alkali metal conducting salt, in particular lithium salt, and in particular solvation of the salt

Coordination between alkali ion, in particular lithium ion, and of

inorganic ionic conductor and / or optionally be weakened by a conductive salt. As a result, advantageously, the transfer coefficient and / or the mobility of the ions, for example lithium ions, and thus the

Ion conductivity, in particular the lithium ion conductivity, influenced and / or increased. In the case of Q ^" , very high transfer rates can advantageously be achieved, whereby - especially in the case of high

Area current densities during charging / discharging - low polarization voltages and thus high performance of a cell equipped with it can be achieved. Because the group Q directly or indirectly to the

Polymer backbone - [A] - attached, can advantageously - compared with mixtures of analogous polymers and analog, but free

or unbound groups Q - a localization of the group Q, for example Q or Q ⁺ or Q ^" , by locating the group Q, for example Q or Q ⁺ or ^" Q ^" , in turn advantageously a diffusion of the group Q and, for example, otherwise possibly associated side reactions, such as swelling of the separator and / or an anode protective layer and / or degradation of the anode, which

Example in the case of low molecular weight ether compounds, could be prevented, as well as the mechanical stability and, for example, binder function can be improved. Moreover, such polymers can have an extremely low vapor pressure compared to liquid electrolytes, making it possible to safely operate a cell equipped with them at higher operating temperatures. Advantageously, by the spacer X - for example, by the nature of the spacer and / or the length of the spacer - and / or the polymer back forming unit - [A] - - for example, by the nature of the polymer back forming unit / s - [A] - and their structure - more

Properties, such as the glass transition temperature and / or others

Properties of the polymer or polymer electrolyte can be adjusted. The spacer X can advantageously be used to adjust in particular the glass transition temperature and / or the mechanical properties of the polymer or polymer electrolyte. The

Polymer back forming unit - [A] - may optionally be optimized for other properties, such as mechanical properties.
