100 years ago batteries didn't have thermal runaway issues.
It's true that currently commercially available EV tech today has a lot of engineering involved to prevent fires.
However, on the bright side safer chemistries and tech ranging from iron phosphate cathodes and sodium ion to solid state are just around corner. Which is pretty cool from an engineering and design perspective.
- woleium 2y agoI wonder what the energy density of 100 year old batteries was.
- sightbroke 2y agoHere's a battery density graph, there are a variety of these out there but give a good approximate comparison of different types. https://media.monolithicpower.com/wysiwyg/Educational/BMS_Chapter_1_Fig4-_960_x_709.png https://media.monolithicpower.com/wysiwyg/Educational/BMS_Ch... Lead acid I believe is what was accessable for automotive purposes 100 years ago. Li-ion cells have about 50-60 years of research in them with maybe 30 where they've been able to be used in automotive applications.
