Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lithium ion batteries face issues such as scarce reserves of rare elements, fluid leakage, and safety concerns due to their liquid electrolyte and layered cathode structure, while existing quantum battery manufacturing methods struggle with high temperature requirements and achieving a sufficient thickness of the electricity storage layer.
Innovation Solution
A core-shell particle energizing method involving semiconductor metallic oxide particles coated with an insulating oxide layer, irradiated with ultraviolet rays, is used to form energized core-shell particles, which are then mixed with a low-temperature thermoplastic polymer to create a thick, safe, and durable electricity storage layer for quantum batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the sintering temperature exceeds 300°C to form the electricity storage layer, then the layer can be formed with sufficient thickness, but the sheet resistance of the bottom ITO electrode increases
Solution Approach 1:
The patent changes the temperature parameter from high-temperature sintering (>300°C) to low-temperature firing (200-300°C), enabling formation of the electricity storage layer without degrading the ITO electrode's sheet resistance
Solution Approach 2:
The patent replaces the traditional sintering process with a low-temperature firing process using organic-inorganic composite precursors, substituting high-temperature thermal treatment with a controlled chemical decomposition process at lower temperatures
2Reliability
If the insulating film is applied to cover TiO2 particles during film forming, then current leakage is prevented, but it becomes difficult to control the required thickness of the whole battery
Solution Approach 1:
The patent incorporates the insulating oxide layer directly into the core-shell particle structure during particle synthesis, performing the insulation function in advance rather than adding a separate film layer, which simplifies thickness control
Solution Approach 2:
The patent uses composite core-shell particles combining semiconductor metallic oxide core with insulating oxide shell, integrating multiple functions (electrical activity and insulation) into a single material system, eliminating the need for separate insulating films

AI summary
A quantum battery manufacturing method includes: providing a p-type semiconductor substrate including a first conductive substrate and a p-type semiconductor layer disposed on one surface of the first conductive substrate; providing an n-type semiconductor substrate including a second conductive substrate and an n-type semiconductor layer disposed on one surface of the second conductive substrate; and forming an electricity storage layer between the p-type semiconductor substrate and the n-type semiconductor substrate, and attaching two sides of the electricity storage layer respectively to the p-type semiconductor layer and the n-type semiconductor layer to form a quantum battery. The electricity storage layer is formed by heating a thermoplastic polymer to soften and become a liquid, mixing the liquid with energized core-shell particles, and coating a substrate with the mixture. Core-shell particles are disposed on a conductive substrate and irradiated with ultraviolet rays for energization.
