Description

Technical Field

[0001] This invention belongs to the field of solid-state battery technology, specifically relating to a solid electrolyte that intelligently achieves ion selective transport through a guided multi-dynamic reversible bond node network. Background Technology

[0002] Polymer solid-state electrolytes (SSEs) have attracted widespread attention due to their advantages such as light weight, ease of processing, low cost, high safety, and strong adaptability to electrode interfaces. In lithium-sulfur batteries, SSEs can also alleviate electrode breakage caused by volume expansion during positive electrode charging and discharging. However, lithium-sulfur batteries still face the problem of lithium metal corrosion caused by the polysulfide shuttle effect. Because polysulfides and lithium ions have similar charge characteristics, conventional SSE matrices cannot effectively selectively transport lithium ions and polysulfides. Furthermore, the low ionic conductivity of SSEs at room temperature hinders their practical application in lithium-sulfur batteries.

[0003] Dynamically reversible bonds exhibit reversible breaking and bonding under external stimuli, allowing cross-linked polymers to rearrange their topological network structure and achieve self-adaptation to electrode interfaces and reinforcing or supporting substrates. Furthermore, these dynamically reversible bonds are often composed of polar groups, possessing unique ion coordination characteristics and the ability to regulate ion migration dynamics. For example, hydrogen bonds have been shown to favor lithium-ion transport, while disulfide bonds have been shown to suppress polysulfide shuttle migration. However, for ion selectivity requirements, the ion dynamics of different types of dynamically reversible bonds conflict, making it difficult to form a synergistic ion selection mechanism through simply stacking multiple dynamically reversible bond networks. Inspired by artificial neural networks, arranging multiple nodes with ion "computation" functions in a special way to form an adaptive ion-directing network holds promise for achieving precise ion-selective "input" and "output." Amphiphilic polymer networks possess ion-directing functions and are widely used for ion separation through the dual effects of electrostatics and steric hindrance. A schematic diagram of the mechanism of a directed multiple dynamically reversible bond assembly node network is shown below. Figure 1 As shown. Therefore, by arranging ion-computation-type dynamic reversible bonds into an amphiphilic polymer network, node computation functions and adaptive structures similar to those of artificial neural networks can be achieved, thereby enabling selective ion transport within the battery.

[0004] To improve the ionic conductivity of solid-state electrolytes, a common approach is to increase the charge-discharge cycle temperature of the battery; however, this generates a strong shuttle effect. Solid-state electrolyte modification or the incorporation of a transition layer can improve the physical barrier and chemisorption performance of polymer materials for polysulfides. However, with increasing sulfur loading and cycle number during chemisorption, the amount of dissolved polysulfides steadily increases, leading to a slowdown in reaction kinetics. Combining the advantages of organic polymers with inorganic fillers to create composite electrolytes can significantly improve the lithium-ion conductivity of the electrolyte. However, the interfacial compatibility between solid-state electrolyte polymers and inorganic fillers is generally poor, requiring complex interfacial modification methods to reduce filler surface energy and enhance filler dispersibility. Therefore, it is of urgent significance to propose a novel solid-state electrolyte preparation scheme that can simultaneously promote lithium-ion conduction, suppress polysulfide shuttle, and improve the electrode interface. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this invention provides a solid electrolyte that intelligently achieves ion-selective transport through a guided multi-dynamic reversible bond node network. This is achieved by dynamically and reversibly modifying the end and cross-linked structures of a hyperbranched cross-linked amphiphilic solid electrolyte polymer, assembling ion-selective functional nodes and a guiding network. Using the polymer solid electrolyte of this invention, the lithium-ion migration capability of the polymer electrolyte can be effectively improved through the intelligent recognition of reversible nodes and the steric hindrance screening of the guiding network, while suppressing anion migration and the shuttle effect of polysulfide ions. Similar to the adaptive structure and node ion "computation" function of artificial neural networks, the reversible structure of the solid electrolyte can also improve the interfacial stability and ion intercalation kinetics of the electrode, exhibiting a triple adaptive effect on ion transport selectivity, electrode interface, and supporting substrate. This significantly improves the electrochemical and mechanical properties of the solid electrolyte, enabling the fabrication of high-performance solid lithium-sulfur batteries, and holds promise for widespread application in the field of novel high-density lithium batteries.

(2) Reversible bond modification of the crosslinked product: If the reactive end of the surfactant monomer does not contain hydrogen bonds and the crosslinking agent contains disulfide bonds, then the crosslinking product is end-modified by dispersing the crosslinking product in anhydrous diethyl ether containing triethylamine, adding the end-modifying reagent under argon protection and stirring, and after the reaction is completed, centrifuging to remove the solvent and residual reagent, and washing with diethyl ether to obtain the modified crosslinking product.
