While advancement in battery technology has been steady, most of this advancement has been evolutionary in nature, based upon refinement in electrode materials and chemistries, and incremental advances in electrolyte stability. However, even with these advances, today’s commercial batteries still charge slowly, provide inadequate power, insufficient capacity and poor safety for today’s rapidly growing portable power needs.
One of the primary problems with current battery designs is that slow ion transport through the battery limits the electrochemical reaction speed and thus the charge and discharge rates. By focusing on new electrode architectures that Xerion Advanced Battery ("XAB") believes will increase electrochemical reaction speeds, the XAB team, led by Dr. Paul Braun of the University of Illinois, is working towards creating a technology that reduces the time necessary to charge and discharge the battery and increases the power density of the battery, while also improving battery safety and capacity.

XAB is working on the development of a structure it believes could simultaneously reduce the diffusion length for both ion and electron transport, enabling fast reaction speed. XAB believes the new architecture could also accommodate the use of high capacity chemistries that exhibit significant volumetric changes during cycling, allowing development of new battery chemistries that retain excellent high power properties, while dramatically maintaining battery capacity per unit volume.
