Yeah, this sort of thing is unlikely to replace lithium batteries in EVs or portable electronics (unless you want to play with more intensely radioactive materials, which is a can of worms). The more likely use case would be for extremely long-lived stationary devices - for example, a remote monitoring system that is only accessed once every few years.
