Flourine is difficult to work with, so these batteries may cost more. Hopefully the energy density offsets the cost.
- rini17 8y agoThis is not nastiness like pure fluorine or hydrofluoric acid, but a salt. It may be somewhat toxic, but it does not require extraordinary handling precautions.
- greglindahl 8y agoI wonder what happens when it catches fire?
- sverige 8y agoI'm sure it burns just like regular lithium-ion batters.[0] The addition of FeF3 probably doesn't change the correct response to the hazards much -- put out the fire if you know how to safely do so with the proper personal protective equipment, otherwise get the heck away.[1] [0] https://www.youtube.com/watch?v=BLc74Qpvweg https://www.youtube.com/watch?v=BLc74Qpvweg [1] http://www.analog.com/media/en/technical-documentation/application-notes/hdr202li_hd220rli_battery_msds.pdf http://www.analog.com/media/en/technical-documentation/appli...
