Energy Storage Device with An Encapsulated Electrode

摘要

Aspects of the disclosure can relate to an energy storage device including at least two electrodes (e.g., an anode and a cathode). At least one of the two electrodes can be formed from lithium or a lithium alloy. The energy storage device can also include an electrolyte solution in contact with the two electrodes and a separator with a melting point higher than a melting point of lithium. The separator can define a boundary between the two electrodes and encapsulates at least one of the two electrodes. The separator can also be impermeable to molten lithium. Thus, when exposed to a temperature that causes lithium from one or more of the electrodes to melt, the separator can prevent contact between molten lithium from one electrode and the other electrode.

1. An energy storage device, comprising:
two electrodes, at least one of the two electrodes including lithium or a lithium alloy; an electrolyte solution in contact with the two electrodes; and a separator that encapsulates at least one of the two electrodes and defines a boundary between the two electrodes, the separator having a melting point higher than a melting point of lithium and being impermeable to molten lithium.
