MAGNETIC WINDOW INTO A BATTERY'S HEART

摘要

Longer-lasting and more powerful lithium batteries could be a boon for electric automobiles as well as personal electronic devices. One of the main drags on battery life is the loss of energy that occurs as lithium ions travel between electrodes. The choice of electrolyte-the solution that bathes the ions inside the battery-affects ion mobility. However, there are few methods available for detecting lithium ion movement while inside a live battery and so choosing the best electrolyte remains a challenge.
