Less Fire, More Power: The Secret to Safer Lithium-Ion Batteries
Root and Branch: Crystalline lithium-metal structures grow out of the anode of a lithium-ion cell in a branching pattern, thus their name, dendrites (from the Greek dendron meaning "tree"). If they grow too long, they can short out the cell. Image: Brookhaven National Laboratory/Science Source

What are dendrites, and why do they cause fires in lithium batteries ...
While the reason why Samsung Galaxy Note 7s have been catching fire has yet to be confirmed, the focus is on the device's lithium-ion batteries. And those familiar with this technology have begun suggesting the battery might have a dendrite problem. For those unfamiliar, dendrites are basically whiskers of lithium that grow inside batteries, and can cause the devices they're powering to ...

Apparently not.
