I want to know the answer to the following question:
In what sort of electrolyte does the oxide layer on an aluminum anode remain stable?
All the background I'm provided with is that "" Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.". Is that enough to answer the question?
Answer: no
