Here is a good perspective to that battery time line development.

“Based in San Francisco, California, NDB Inc. was founded in 2012 with the objective of creating a cleaner and greener alternative to conventional batteries. The startup introduced its version of diamond-based batteries in 2016 and announced two proof-of-concept tests in 2020. It’s one of the firms that is attempting to commercialize radioactive diamond batteries.”

And those are on par with the timeline of Energizer and the AA Lithium Battery. What’s interesting, is how long it tookEnergizer to release the 9v lithium battery to the market. I think that was double the timeline.
