When a large lithium battery (car, Powerwall) combusts, what area is contaminated with hydrogen fluoride? Since its a gas (unless dissolved in water) would it dissipate without trace or leave behind toxic residue ?
- tristanj 11y agoI don't think there's any fluoride in these batteries. The Model S uses Lithium Nickel Cobalt Aluminum (NCA) batteries and the powerwall uses Lithium Nickel Manganese Cobalt (NMC) batteries. Neither contain any Fluorine, and since they produce electricity using chemical reactions not nuclear reactions, no new elements will be produced. Not too sure what you're asking.

- clumsysmurf 11y agoSeems the issue is not settled. NMC were also tested: http://www.ncbi.nlm.nih.gov/pubmed/25714114 http://www.ncbi.nlm.nih.gov/pubmed/25714114 and "More HF is generated per cell as the number of cells increases. The NMC cells tested generate significantly less HF gas than the LFP cells. However, only one cell type from a single supplier was tested so it is impossible to conclude if this is a general characteristic of NMC cells." http://www.egvi.eu/uploads/Scania%20-%20Abuse%20testing%20of%20E-vehicle%20battery%20cells%20and%20packs-aat.pdf http://www.egvi.eu/uploads/Scania%20-%20Abuse%20testing%20of...
- clumsysmurf 11y agoI'm not sure why my question in getting down voted. The Tesla (and other vehicles) were specifically mentioned in "Proceedings from 3rd International Conference on Fires in Vehicles - FIVE 2014 October 1st-2nd, 2014 Berlin, Germany" http://publications.lib.chalmers.se/records/fulltext/204919/local_204919.pdf http://publications.lib.chalmers.se/records/fulltext/204919/...
