While it shares many properties with titanium and molybdenum, it surpasses them in stability, particularly in high-temperature acidic environments (above 100°C) where even noble metals like platinum can struggle. \u003c\/p\u003e\n\u003cp\u003e(1) In \u003cstrong\u003ebattery\u003c\/strong\u003e system, tantalum foil current collectors enable the study of batteries using imide salts (like LiTFSI) without the need for fluorine-based additives.
