wrong type of lithium . That article is about lithium iron , these are lithium Titanate LTO .
Lto has no carbon in it , no problems with fire , explosion , thermal nuclear meltdown , well you get the idea.
Toshiba is now making an LTO cell they call them SCiB , here is a little info from Toshiba:
What is SCiB™?
Toshiba SCiB™ is a highly safe rechargeable battery with six outstanding characteristics.
By using oxide-based materials (Lithium Titanium Oxide), SCiB™ is designed to prevent thermal runaway resulting from short circuiting caused by physical stress.
Furthermore, SCiB™ has various superior characteristics, including a long life exceeding 15,000 charge/discharge cycles, rapid charging time of 6 minutes, input/output current densities comparable with capacitors, and operation at temperatures as low as -30°C.
the cells i'm using sold for over $100/ea
