Lithium-Ion Power Warning

So there was a serious fire in the battery room in a state of the art hybrid power ferry.

https://gcaptain.com/fire-and-gas-ex...power-warning/

Not a whole lot of solid info to go on, but it did get my attention, and it would have REALLY got my attention if I had a Lithium battery pack.

The lithium battery system was supplied by Corvus energy systems. Their website says things like "State of the Art Monitoring System", "True cell level thermal runaway isolation", Patented Safety System". After the fire, they "issued recommendations to operators not to sail without communication between the shipboard energy management system and the battery packs, as well as what to do in case of a gas release or “thermal runaway situation".

Whether Corvus screwed up or the operators screwed up,"twelve firefighters were taken to the hospital for exposure to hazardous gases associated with the batteries."

So can our LiFe experts shed some light on this?

Was the battery technology LiFePO4??
What were the hazardous gases?
What caused the original fire?
What caused the later explosion?

Could this happen to a typical sailboat battery bank, which is quite a bit smaller, and discharges/charges at a lower rate?

Re: Lithium-Ion Power Warning

Entirely different chemistry than LiFePO4.

From Corvus’ website:

“The Corvus Energy lithium ion batteries are based on a LG Chem's patented Nickel Manganese Cobalt (NMC) Polymer chemistry. NMC Polymer provides approximately 25% more energy and power density compared to Lithium Iron Phosphate (LiFePO) formulas. When combined with the ultra low internal resistance of the cell, the batteries provide a much higher usable power source that may be used to replace diesel scale power in many industrial applications.”

Re: Lithium-Ion Power Warning

Thanks, I couldn't find that.

I'd gladly give up 25% energy density if my batteries didn't explode.

More like 50% but I definitely agree.

Re: Lithium-Ion Power Warning

Sounds like the same chemistry that plagued the Boeing planes.

That was Lithium Cobalt, apparently GS Yuasa LVP10 cells, specifically Lithium Cobalt Oxide ( LiCoC2)

Closely related to LCO or LiCoO2

Other lithium-ion chemistries, all less safe than LFP, include

LiNiCoAlO2 (NCA)

LiMn2O4 (LMO)

LiNiMnCoO2 (NMC)

And many many more

Li Ion has no place on crusing boats except in your drone or cellphone/pc

This sounds like they determined that it was either operator error or installer error, hence this specific warning.

Absolutely agree.

Except for LFP and LTO.
