Flexible Metal-Air Battery Case for Constant Electrode Spacing

The patent applies the dynamics principle by making the battery case flexible and capable of changing shape. The case transitions from a rigid fixed structure to a dynamic flexible structure that can adapt its internal volume. The flexible case is driven by a driving mechanism that adjusts the case's shape based on the remaining amount of metal ingot, thereby dynamically maintaining the optimal distance between anode and cathode throughout the reaction process.

The patent applies the parameter changes principle by changing the physical state and geometric parameters of the battery case. The case changes from a fixed rigid state to a variable flexible state, with its internal volume and shape parameters being adjusted according to the reaction progress. The driving mechanism modifies the case's geometric parameters (length, width, height) to compensate for the decreasing anode volume, ensuring constant electrode spacing.

The patent transforms the static rigid case into a dynamic flexible case with adjustable geometry. The flexible case incorporates a driving mechanism that actively adjusts the case's internal volume based on feedback about the metal ingot's remaining amount, enabling the system to adapt to changing reaction conditions and maintain optimal electrochemical performance throughout the battery's operational life.

The patent implements a feedback control system where the driving mechanism monitors the remaining amount of metal ingot and adjusts the flexible case's shape accordingly. This feedback loop ensures that the distance between anode and cathode is continuously maintained at the optimal value, preventing reaction instability and extending the battery's sustainable operational period.
