Sheet-Type Discrete Element for Thin Film Storage Substrates

The patent introduces an intermediate layer between the metallic lithium anode and the environment (moisture and air). This intermediary layer acts as a protective barrier that prevents direct contact between the reactive lithium and harmful external factors, thereby maintaining high energy density while reducing safety concerns and handling difficulties.

The patent applies preliminary action by pre-treating the substrate surface before coating to enhance layer adhesion and uniformity. This preliminary preparation step simplifies subsequent coating processes by creating an optimized surface that naturally promotes even deposition, thereby reducing the need for complex multi-step coating procedures while maintaining high manufacturing precision.

The patent employs parameter changes by optimizing the substrate production parameters (such as temperature, pressure, and material composition) to achieve uniform thickness with reduced variation. By carefully controlling and adjusting these parameters during substrate manufacturing, the patent achieves high thickness uniformity that prevents layer defects like cracks and detachment, while avoiding excessive production complexity through systematic parameter optimization.

The patent applies universality by designing the substrate to serve multiple functions: it acts as both the structural base and the primary moisture barrier. By integrating the encapsulation function directly into the substrate material or structure, the patent eliminates the need for separate encapsulation layers, thereby improving reliability through moisture protection while reducing device complexity and production costs.
