Research shows electric vehicles could charge 500% faster in cold conditions thanks to a new manufacturing method.
In a new study published March 17 in the journal Joule, scientists outline how they can significantly improve the charging speed of lithium-ion batteries at temperatures as low as 14 degrees Fahrenheit (minus 10 degrees Celsius) by changing the design of the battery and the chemical reactions that occur during the charging process.
“The researchers were able to simultaneously achieve extremely fast charging at low temperatures without compromising the energy density of the lithium-ion battery,” said Neil Dasgupta, the study's author and an associate professor of mechanical engineering and materials science at the University of Michigan.
