Comparison of Graphite vs. Silicon and Lithium Metal Anode Technology for High-Density Batteries The heartbeat of our modern existence is measured in percentages. From the smartphone in your pocket to the electric vehicle (EV) in your garage, we are living in an era defined by the lithium-ion battery. Yet, for decades, the progress of battery technology has felt incremental rather than revolutionary. While software and processors evolve at lightning speed, the physical battery has remained tethered to a chemistry developed in the late 20th century.

Introduction The pursuit of the perfect battery has always been a battle against "dead weight."  In the quest  for higher energy density, every gram of material that does not directly contribute to storing energy is a liability.
