Much longer lasting and more easily recyclable batteries do exist, iron nickel batteries for example, which are extremely robust, last for decades, and can be melted down and rebuilt when they do fail. But of course have the downside of costing a lot more for the same amount of energy storage because nickel is pretty expensive. I wouldn't bet on them being that common of a battery in the future, but if I wanted a battery that would last me the rest of my life and I had the money to put down for it, I would probably put my money on an iron nickel battery.
