Battery revival method draws skepticism from engineers
Regeneration of used batteries via electrode–electrolyte interphase dissolution
A new paper proposes regenerating used batteries by dissolving the electrode–electrolyte interphase, but Hacker News commenters are unconvinced. One argues the technique needs risky chemical injection into dangerous cell chemistries, and calls for banning liquid-electrolyte NMC, LFP, and LiPo cells in favor of solid-state designs with ceramic separators, such as those from ProLogium. Another notes that periodic 'batteries that last forever' studies rarely reach implementation.
NMC are extremely dangerous under deflagration, and LFP create huge amounts of colorless and odorless hydrogen gas that has already blown up many improperly engineered buildings that used them and assumed they were "safe".

Just like the periodic news about a new study on a method that makes batteries last effectively forever, this is unlikely to be implemented.

Yup, saw this in a documentary. A bunch of tourists were stranded on a desert island, but this professor had them re-energize them with some coconuts and bananas.
Longest 3 hour tour ever.
