Tungsten (W) foil is a high-performance refractory material used in electrochemical systems that operate under extreme temperature and aggressive acidity conditions.
(1) In battery system, tungsten foil is one of the few metals that is electrochemically inert in the highly corrosive acidic ionic liquid electrolytes (such as AlCl3) used in aluminum-ion batteries. As for anode-free battery, tungsten foil is used as negative current collector since it does not readily alloy with lithium. This allows researchers to study lithium plating and stripping on a "pure" non-reactive surface.
(2) In electrolyzer application field, W foil is a robust catalyst substrate for the Hydrogen Evolution Reaction (HER). Its ability to withstand both acidic and alkaline environments makes it a durable platform for water-splitting technology.
(3) In high temperature molten salt electrochemistry system, tungsten foil is used in thermal batteries where temperatures reach levels that would cause molybdenum or nickel to soften.
