In electrochemical storage devices we use tungsten foil as an electrolyte, [we are use as electrolyte acids only HNO3, H2SO4, H2C2O2. WHY NOT USE OF BASE, ALKALIES, or SALTS, etc.]
I assume you meant H2C2O4 and not H2C2O2.
I am not a battery expert by any means but I'm not aware of any cells that use tungsten as an electrolyte. As an electrode, or electrodes (especially in the shape of grills), yes, but not as an electrolyte. Dry cells by the way use NH4Cl paste, a salt, as an electrolyte and some cells do contain bases. The electrolyte in Li ion batteries is LiX, a lithium salt.
