What is NEES?

The Nanostructures for Electrical Energy Storage (NEES) EFRC is a multi-institutional research center, one of 46 Energy Frontier Research Centers established by the US Department of Energy in 2009. The group's focus is developing highly ordered nanostructures that offer a unique testbed for investigating the underpinnings of storing electrical energy.

The center studies structures that are precise - each at the scale of tens to hundreds of nanometers and ordered in massive arrays - and that are multifunctional - able to conduct electrons, diffuse and store lithium ions, and form a stable mechanical base. The scale and control of experimentation gives NEES researchers an exclusive gateway to probing fundamental kinetic, thermodynamic, and electrochemical processes.
