Unless you're a battery manufacturer ... A battery that never needs to be replaced would be a real game changer for the business. I hope I'm wrong, but I don't think any manufacturer would touch it for fear of losing their replacement business. Maybe you've noticed that as LED retrofit light bulbs have fallen in price, their rated lifetimes have gotten shorter. The early ones were rated for 50,000 average hours; many now are rated for 10,000-20,000 hours. The same thing happened with compact fluorescents, which quickly declined from 10,000 hours to 6,000. This parallels what happened with incandescent light bulbs. When mass production tungsten filament bulbs first came on the market, they burned for ~2500 hours. Then the manufacturers formed a cartel and agreed to limit their bulbs' lives to 1000 hours. I suppose it sounds cynical, but I expect that if this battery ever makes it to the market, it will have a deliberately limited lifetime. I can see them making several different versions, identical except for price and the configuration of the built-in self-destruct mechanism.
