This invention discloses a photolithographically patternable lithium-ion electrolyte, its preparation method, and its applications. The electrolyte is a photolithographically curable lithium-ion electrolyte composition, comprising, by mass percentage, LiTFSI, polyethylene glycol methyl ether methacrylate, bisphenol A ethyl oxide dimethacrylate, fluoroethylene carbonate, succinic acid, 2-hydroxy-2-methyl-1-phenyl-1-propanone (HMPP), 3-(isobutyryloxy)propyltrimethoxysilane, and 2-methyl-2-acrylate-2-hydroxyethyl. This invention also discloses a stepwise preparation method for this composition and its applications in micro-energy storage and ion-electronic devices such as micro solid-state batteries, ion-controlled transistors, and neuromorphic devices. This electrolyte can be patterned at the micro-nano scale using standard photolithography processes, exhibiting excellent lithium-ion conductivity, electrochemical stability, mechanical flexibility, and optical transparency. It also shows good interface compatibility with gold electrodes / silicon wafers, requiring no additional etching or transfer processes. This solves the technical problems of existing solid-state electrolytes being difficult to fabricate at the micro-nano scale and incompatible with microelectronic processes, and has broad application prospects in the fields of micro-nano fabrication and micro-devices.

The application discloses a liquid-phase high-entropy carbide-silicon carbide composite ceramic precursor, a composite ceramic and a preparation method. The precursor comprises at least four of Ti, Zr, Hf, V, Nb, Ta, Mo and W elements, carbon element and silicon element, and the mole number of each metal element accounts for 5-35% of the total metal mole number of the precursor. The liquid-phase precursor contains a solvent selected from one or more of toluene, xylene, tetrahydrofuran, ethylene glycol dimethyl ether and ethylene glycol diethyl ether, and the change rate of the viscosity of the precursor is not greater than 10% after being stored at 25 DEG C for 3 months. The precursor can form the high-entropy carbide-silicon carbide composite ceramic with the metal element, the silicon element and the carbon element uniformly distributed in the nanometer size after being cracked.
