separator film 45 divides the anode 40 and cathode 35 of the battery 5 typically a dielectric separator 45 is used to separate the cathode portion 35 and the anode portion 40 more typically a polymer separator is used the outer surfaces of the current collectors 15 are connected in electric communication to the output of the battery 5 the device assembly is typically soaked in electrolyte solution and packaged in this example the battery assembly 5 is soaked in lithium phosphorous fluoride lipf6 1m in an ethylene carbonate diethyl carbonate ec dec electrolyte solution 1 1 by volume pressed and encapsulated in a coin cell alternately the battery 5 may be separately packaged into a pouch cell any convenient form of flexible or rigid packaging methods for the battery 5 may be utilized the capacities of the batteries 5 made with the current collectors 15 may be measured to be 150 mah g for lithium cobalt oxide lco half celt 158 mah g for lithium titanium oxide lto half cell and 126 mah g for the full cell flexible electrochemical device 5 typically does not appreciably deteriorate or lose efficiency due to bending in some embodiments a fibrous material 30 is infused with an at least partially electrically conductive nanomaterial 20 to define a current collector 15 the resultant combination may be coated or deposited with a lithium metal oxide electrode portion 10 or the like to define an electrode 12 at least two of these fabricated electrodes with different lithium metal oxide coatings may be separated by a dielectric separator 45 to define a battery an electrolyte 70 may be dispersed or infused in the lithium metal oxide electrode portion 10 and or the fibrous nanomaterial current collector.
