Scientists create new electrolyte mixture to prevent battery fires
believe they have found a solution to prevent lithium-ion electric vehicle batteries from igniting at high temperatures.
“One of the biggest challenges in the battery industry is this safety issue, so there’s a lot of effort going into trying to make a battery electrolyte that is safe,” theConventional lithium-ion battery electrolytes comprise a lithium salt dissolved in an organic solvent like ether or carbonate, resulting in a flammable mixture.
Conventionally, less than 50% of a polymer-based electrolyte’s weight is made up of salt. Huang increased this figure to 63%.It should be noted that the electrolyte she created also contained flammable solvent molecules. Instead of failing at high temperatures like most lithium-ion batteries, those containing SAFE continued to operate at temperatures between 77–212 degrees Fahrenheit .
