Chemistry Change in Batteries Could Make for Safer Electric Cars
Abstract:
The powerful lithium-based batteries used in electric vehicle systems, laptops and cell phones are prone to overheating and even blowing up, but adding less than a gram of a new substance could keep both temperatures and costs down, federal researchers say.
The molecule, developed by researchers Khalil Amine and Zonghai Chen at Argonne National Laboratory, is being tested as an additive in the electrolyte of lithium batteries to keep cell voltage from going too high.
In the lab, Amine and Chen discovered they could make a molecule based on boron and fluorine and add a tiny amount of it to each cell to control charging. When the cell exceeds the safe voltage level, Amine explained, the molecule picks up electrons and keeps the cell charge from going up.
