Will Lithium Last Indefinitely?

When you're talking about things that are valued for their physical properties, those tend to be. things that worry me, because people will come uFP with substitutes. And all those things coming together will be the reasons why i'm afraid of being invested in something like lithium, because i don't it will last. That's always my prolm of bit divessus tend to like things that are cheap,. unlike the tri on 12 months basis or something.
