Nickel-63 is pretty safe as radioactive elements go. It's proposed as an energy source for pacemakers.

Standford says 0.1mm of plastic will absorb all emissions.

At this moment, 1 gram of radioactive Nickel-63 costs around 4,000 USD. Nickel-63 isotope does not occur in nature, it is obtained by irradiating Nickel-62 inside a nuclear reactor.

The world needs breeder reactors anyways, build out a lot of gen 4 plants and make Nickle-63 to boot.

What happens when the casing get punctured? When you mass produce these devices these things will happen.

Probably the same as with tritium lumes. Only dangerous if you swallow the unshielded nickel.

Surely the battery itself would have sufficient protection on top of the devices chassis offering protection.

I can't say a Lithium Ion battery leaking in the body would bode very either.
