The 10 Minute Charge: EVs Hit Major Milestone

A team of scientists at Penn State University in Pennsylvania has developed a method through which lithium-ion batteries can heat up to 140 degrees Fahrenheit for 10 minutes and then rapidly cool down to ambient temperatures, allowing them to charge in that short time. The self-heating battery uses a thin nickel foil with one end attached to the negative terminal and the other extending outside the cell to create a third terminal. A temperature sensor attached to a switch causes electrons to flow through the nickel foil to complete the circuit.…
