Silicon Nanoparticles (SiNPs) as a source for chemical energy storage in Lithium-Ion Batteries (LIBs) are increasing in popularity due to the high theoretical gravimetric capacity Silicon possesses (3500 mAh/g).  SiNPs have nearly 10x the capacity of current state-of-the-art graphite anodes used in most batteries today.  Increasing the capacity of batteries by an order of magnitude is appealing for many reasons, however several challenges arise from the massive increase in energy storage that must be further understood before implementation into industry.  Volume of SiNPs increase by more than 350% when charging and discharging, which results in pulverization of the particles yielding poor efficiency and cycle life.  In addition, new process methods must be developed to control the formation and structure of the Solid Electrolyte Interphase (SEI).  Here, we present our results towards improving the performance of SiNPs anodes in LIBs in the hope of achieving the US Dept. of Energy’s goal of $100/kWh.
