Solid-State Electrolytes. True all solid-state ionic electrolytes such as lithium phosphorus oxynitride (LiPON) provide adequate conductivity for use in thin film solid-state batteries (see Sec. 35.8.)... 

Other methods are also closely related to the resulting surfaces of the carbon materials. For example, an artificial passivating SEl film is formed when a suspension of n-butyl lithium/hexane, lithium naphthalene, or molten lithium is used, first to treat the graphite and then to react with electrolytes. This results in a higher reversible capacity of the graphite, 430 mAh/g, and higher initial coulombic efficiency. Apparently, the first treatment can passivate active defects in carbon materials. The merit of this process is that it is independent of the specific carbon materials. However, it is complicated and the formed SEl film is still not comparable with that obtained by electrochemical reduction. In another reported case, deposition of an inorganic ionic conductor, lithium phosphorus oxynitride (LiPON), can also lead to improvement in electrochemical performance. 

The battery chemistry is composed of solid-state films and uses Uthium-phosphorus-oxynitride (LiPON) solid-state electrolyte developed by Oak Ridge National Laboratory. The cathode is made from LiCo02 and the anode uses a very small amount of lithium metal.
