One problem with Lithium Ion batteries is that they have a slight penchant for failing in a spectacular way when charged improperly or if heat builds up past a critical level. Some researchers have come up with a simple idea to prevent this from happening, applying a polyethylene film to one of the electrodes which changes size as the temperature changes, breaking the circuit when a certain temperature is reached which shuts the battery down. Once the temperature falls the circuit reconnects and the battery is usable once again. They do not expect this to impact the normal functionality of the battery, giving an extra level of safety with no performance cost. You can follow the links from Slashdot to see the research paper yourself.
"Scientists have designed a lithium-ion battery that self-regulates according to temperature, to prevent itself from overheating. Reaching extreme temperatures, the battery is able to shut itself down, only restarting once it has cooled. The researchers designed the battery to shut down and restart itself over a repeated heating and cooling cycle, without compromising performance."

Awesome tech, still doesn’t
Awesome tech, still doesn’t prevent a lipo from going up that has a puncture. When the lithium gel inside the Lipo has a charge and is oxygenated, you get to see some fireworks.
Might want to change the title to “cant Explode from overheating”

Your right, but the title is
Your right, but the title is still misleading. Battery chemistry like LiFepo4 are safer. They run less risk of exploding on you when poked.
Maybe the average person knows the difference between the Lipo and Life but I doubt it.
Do we know if this can
Do we know if this can prevent or lessen fires due to punctures of Li batteries?
Here is a stupid example of what can happen when someone abuses a battery.
Just wondering if we know.
Nope, please refer to
Nope, please refer to previous meme.

1. Lithium-Ion and Lithium-Polymer are NOT the same thing.
2. Only Lithium-Polymer “explodes”, NOT Lithium-Ion.
