Engineering Contradiction Analysis
1Ease of manufacture
If a mixing process in ion solution phase is used to synthesize lithium manganese oxide-carbon nano composite, then the composite can be synthesized with multiple components, but the process requires multiple steps including solution reaction, crystal growth, strong acid or alkali treatment, and thermal treatment
Solution Approach 1:
The patent combines multiple synthesis steps (solution reaction, crystal growth, template removal, and alloy formation) into a single co-vaporization process. Multiple metal precursors and carbon sources are simultaneously vaporized and deposited onto the substrate, forming the composite structure in one step without requiring sequential processing.
Solution Approach 2:
The invention extracts and eliminates the intermediate steps involving strong acid or alkali treatment and separate thermal treatment for alloy formation. By using co-vaporization, the process directly forms the desired composite structure without needing to remove templates or perform separate crystallization steps.
2Manufacturing precision
If multiple steps including strong acid or alkali treatment are used to remove template components, then the composite structure can be formed, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The patent incorporates template components directly into the vapor deposition process, eliminating the need for subsequent removal steps. The carbonaceous material serves as both the carbon source and structural template during co-vaporization, forming the desired nanostructure directly without requiring post-synthesis treatment.
Solution Approach 2:
The co-vaporization process continuously forms the composite structure in a single uninterrupted step. Multiple precursors are simultaneously vaporized and deposited, maintaining continuous formation of the composite without interruption for intermediate treatments or separate processing steps.
3Productivity
If a simple co-vaporization process is used to synthesize hybrid composite particles, then mass production can be achieved, but the particles need to be effectively dispersed and attached to adherend surface
Solution Approach 1:
The patent replaces mechanical mixing and attachment processes with electrostatic field-based deposition. The electrostatic field automatically disperses the vaporized particles and attaches them to the adherend surface, eliminating the need for mechanical dispersion methods that are difficult to scale up.
Solution Approach 2:
The invention changes the state of the precursors from solid/liquid to vapor phase, enabling uniform dispersion through gas phase transport. The electrostatic field parameters are optimized to control particle attachment, ensuring uniform distribution on the adherend surface while maintaining mass production capability.

AI summary
Disclosed are a large-scale composite synthesis system, a reactor therefor, and a synthesis method using the same, wherein two or more different samples are vaporized in respective vaporizers, and are then fed into a reactor that has a relatively large transverse cross-sectional diameter compared to the connector for transporting the samples in a gas phase and is maintained at a temperature lower than that of the connector, thus producing a powder composite, the composite being synthesized while being electrostatically attached to an adherend surface.
