So far, anything that stores energy in density is pretty volatile if used incorreclty. Be it plutonium, gasoline, diesel or lithium ion batteries.
21 months of DAILY charging and discharging.... My Nissan leaf has failed to burst into flames or explode... so far...I'll keep ya'll posted.
How about the BILLIONS of Li batteries in tablets, laptops, smart phones, cordless tools etc. etc. etc.. The failure rate, vs. the sheer number of Li batteries in use today is pretty infinitesimal. Between our house & barn/shop we have well over 40 Li batteries....
16+ Li Cordless Tool Batteries (Porter Cable, Ryobi & Milwaukee)
4 Li Tablets
3 Li Smart Phones
7 Li Laptop Batteries
6 Home Phone Li Batteries
4 Li batteries for boats in my shop
5 Li Remote Control "RC" Hobby Batteries
and I know I have left a bunch out....
Heck Tesla sold 17,000 cars last quarter alone, the Chevy volt is now over 100,000 and the Leaf I believe is now over 200,000. Dangerous failure rates based on those numbers have a .
then a lot of zeros in front of it. More people die in bathtubs than have died from Li batteries. Should we curtail the use of bath tubs....?
I have had LiFePO4 on board for 4.5 years now (approaching 750 cycles most to 80% DOD) and I consider my LFP system far safer than any lead acid battery system I have ever used or installed on a boat because of all the redundant protection systems that prevent the battery from getting over charged or over discharged.......
The vast number of deaths attributed to Li batteries are kids swallowing Li "button batteries", about the same size as a nickle. Clearly we need to stop using nickles...
It seems everyone wants to compare LiFePo4 (what is being used on boats) to the Boeing incident, which occurred with a very high strung Li chemistry (LiCoO2), and that is like comparing the properties of cow dung to gasoline.
Imagine if glass
were invented today. Neither would ever be allowed with today's level of thinking... Think about it, really...
We need to remember that ALL batteries can be dangerous!
