I have real doubts about this tech being viable on the market. For one thing there's a huge psychological barrier for many people, as anyone who has worked in nuclear power can tell you. There's also the issue that this relies on Nickel-63, and while unfortunately info on total demand/production is significantly paywalled, I don't think it's enough to support something like this. Outside of chromatography and explosives detection, there isn't a huge market for it, which implies low production. It is also true that it isn't as dangerous as many other isotopes, but unless these batteries are sealed to last 100+ years, disposal/recycling is going to be an issue. That will add cost, even if the production of Nickel-63 can be scaled up from (probably) 10's of kg's to 1000's of kg's annually.
