No more burning batteries? Stanford scientists turn to AI to create safer lithium-ion batteries

[font size=4]Researchers have identified 21 solid materials that could replace flammable liquid electrolytes in lithium-ion batteries, improving the safety of electronic devices like cellphones and laptops.[/font]

[font size=3]Scientists have spent decades searching for a safe alternative to the flammable liquid electrolytes used in lithium-ion batteries.
Now Stanford University researchers have identified nearly two-dozen solid electrolytes that could someday replace the volatile liquids used in smartphones, laptops and other electronic devices. The results, based on techniques adapted from artificial intelligence (AI) and machine learning, are published in the journal Energy & Environmental Science.
“Electrolytes shuttle lithium ions back and forth between the battery’s positive and negative electrodes,” said study lead author Austin Sendek, a doctoral candidate in applied physics and first author on the paper. “Liquid electrolytes are cheap and conduct ions really well, but they can catch fire if the battery overheats or is short-circuited by puncturing.”
Battery fires led to the recent recall of nearly 2 million Samsung Galaxy Note7 smartphones, the latest in a series of highly publicized lithium-ion battery failures.
