Haven't these been around for ages? All the heavy crypto servers I've worked with have had nuclear batteries because they kept keys in volatile memory, and the trickle current keeps the supply of power from being accidentally interrupted and dumping all the keys. Is it just the new form factor that's novel?

Higher power output, smaller form factor, cheaper manufacturing process and safer to handle
