Fifty years after the birth of the rechargeable lithium-ion battery, it’s easy to see its value. It was manufactured in small volumes by Exxon, appeared at an electric vehicle show in Chicago in 1977, and served briefly as a coin cell battery. Did Exxon invent the rechargeable lithium battery? But then Exxon dropped it.

Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to replacing the graphite anode with a lithium-metal anode. However, one of the main technical hurdles to making the switch is that lithium metal anodes are not compatible with conventional electrolytes.
