The lithium-ion battery analogy seems fitting: When we're not careful about sourcing those modern batteries from a trustworthy supply-chain, they tend to explode and injure the user.

It is, and intentionally so.
NiCd batteries could also sit on a shelf forever, holding their charge. They had virtually no self-discharge, which was super-convenient.
They came in standard form factors (AA, AAA, 9V, etc.).
I really liked NiCd batteries.
But realistically, you couldn't sell a phone or laptop in 2025 which ran on them.
