Title:
ZINC-SILVER STORAGE BATTERY USED FOR MULTIPLE TIMES IN MICROGRAVITY ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2024/077830
Kind Code:
A1
Abstract:
A zinc-silver storage battery used for multiple times in a microgravity environment, comprising a housing, a positive electrode, a negative electrode and an electrolyte which are located in the housing, and a separator that separates the positive electrode from the negative electrode. Positive and negative current collectors respectively extend out of the housing from the positive and negative electrodes and are respectively sleeved with positive and negative electrode insulating sleeves. The upper edges of the positive electrode and the negative electrode are both coated by insulating films. In the present invention, the upper edges of the positive and negative electrodes of the battery are coated in an insulating manner, and the positive and negative electrode current collectors are coated with the insulating sleeves, so that the situation that the sponge zinc separated out in multiple charging processes of the battery in a microgravity environment floats upwards to form a "zinc bridge", and is communicated with the positive and negative electrodes to cause internal short-circuit failure of the battery is effectively avoided.
