Low temperatures thicken the liquid electrolyte in batteries, slowing the movement of lithium ions between electrodes. This phenomenon reduces electrical current and increases the time needed to ...

In batteries, ions carry a current of energy from anodes to cathodes and back again through electrolytes. Understanding how exactly ions move within batteries can lead to greater degrees of control ...

Because of their coordinated movement, the slow ion movement also slowed the electrical current. “We found that the ions that were flowing all right in the conductor, but they had to go through this ...
