CREATE TABLE table_75749 ("Type" TEXT, "Zinc\\u2013carbon" TEXT, "Alkaline" TEXT, "Li-FeS 2" TEXT, "NiCd" TEXT, "NiMH" TEXT)

What is Li-FeS 2, when Type is Nominal Voltage?
SELECT "Li-FeS 2" FROM table_75749 WHERE "Type" = 'nominal voltage'
SELECT "Li-FeS 2" FROM "table_75749" WHERE "Type" = 'nominal voltage'
