Nano-structured Anode Composition for Lithium Metal Batteries

The patent applies local quality by creating a non-uniform lithium distribution pattern through controlled deposition on the anode surface. The lithium is deposited in a dispersed manner rather than uniform coating, creating local variations in lithium concentration that prevent dendrite formation while maintaining high overall capacity. This localized control of lithium distribution resolves the contradiction between high capacity and safety.

The patent employs preliminary action by pre-depositing lithium on the anode surface before battery operation begins. This initial lithium layer serves as a buffer that controls subsequent lithium deposition patterns during cycling, preventing dendrite formation from the outset. The preliminary lithium deposition establishes a safe operating pattern that maintains both high capacity and safety throughout battery life.

The patent extracts the dendrite prevention function from complex multi-component systems and implements it through a simple controlled lithium deposition process. By removing unnecessary separator modifications, coating layers, and complex structures, the invention achieves dendrite prevention through essential lithium deposition control alone, significantly reducing device complexity while maintaining safety.

The patent applies self-service by enabling the lithium deposition process to automatically regulate its own pattern without external control mechanisms. The controlled deposition method creates a self-organizing lithium distribution that inherently prevents dendrite formation through the physical chemistry of the deposition process itself, eliminating the need for complex active control systems or monitoring devices.
