This is just more of the usual alarmist nonsense about lithium ion
batteries. This should be the kind of forum where we discuss the design
of lithium ion battery chargers and lithium ion battery condition
monitors - which could, in principle be designed to discharge the
battery if the internal temperature of the battery rose high  enough to
suggest a risk of runaway self-discharge.

 Perhaps you'd like to explain to the lady who's house burned to the ground
and her similarly stricken neighbours that this is all just an "alarmist
fantasy" Bill.

Alarmist fantasy in action... https://www.sandiegouniontribune.com/2024/05/18/battery-fire-at-storage-facility-in-otay-mesa-keeps-reigniting/
also: (different incident) "On April 19, 2019, a fire captain, a fire engineer and two career firefighters suffered serious injuries dealing with a thermal runaway incident at a 2.16-megawatt battery facility in Surprise, Arizona. According to a Underwriters Laboratories report on the incident, When firefighters opened a door to the building, a 75-foot jet of flame extended outward from the doorway. The fire captain was blown over 70 feet against a chain-link fence surrounding the building. The entire hazardous materials team lost consciousness from the blast. "
Not to be an alarmist, just be aware that even professionally managed lithium batteries can do bad things. Don't keep them in your house...
