Corrosion protection using protected electron collector
View Patent ↗A battery comprises a first electrode, a second electrode, an electrolyte, and an electron collector associated with the first electrode, the electron collector having a surface treatment, such as a protection layer, that reduces corrosion of the electron collector by the molten salt electrolyte.
1. A battery comprising:
a first electrode;
a second electrode;
a molten salt electrolyte; and
an electron collector, the electron collector being substantially aluminum metal and associated with the first electrode,
the electron collector having a protection layer extending between and fully separating the first electrode and the electron collector, the protection layer including an aluminum alloy having a lower aluminum content than the electron collector and reducing corrosion of the electron collector by the molten salt electrolyte.
