Re: EVs Pure Electric Vehicles

I used to live in upstate NY where it could get to -40 below zero. Now I live in Arizona where it can get to over 110 F at times. It sure nice the new lithium batteries can tolerate these extremes. NiMH are good but are known to fail at 140F or higher.

The NanoSafe Advantage-
Altairnano nLTO-based batteries can operate at temperatures as low as -50°C (-58F)and as high as +75°C (167F)— again, with no unsafe characteristics. To put the NanoSafe batteries to the test, Altairnano performed “hot box” exercises on its batteries at temperatures up to 240°C (115F)— which is more than 100°C above the temperature at which graphite-based batteries can explode — with zero explosions or safety concerns. Altairnano has demonstrated that their NanoSafe batteries can be changed to 90% of their room temperature charge even at -30°C. This has application in a wide variety of markets including electric vehicles, where they are required to operate in sub-zero conditions, and aircraft and military applications where at high altitude temperatures are frequently in the -30°C range.
At high temperatures Altairnano has demonstrated that batteries constructed using their nano-electrode materials are safe at temperatures up to 250°C. This extreme temperature operation has application in dessert environments for both civilian and military needs.
