Abstract
 This pa­per pre­sent the re­sults of re­se­arch of be­ha­vi­o­ur of pho­non sub-system in ul­trat­hin co­a­tings that are ap­plied on elec­tro­des in Li-ion bat­te­ri­es and that in­cre­a­se the ef­fi­ci­ency of ion tran­sport. Using the met­hod of Green fun­cti­ons it was de­mon­stra­ted that in ul­trat­hin films, in­cre­a­sed mec­ha­ni­cal oscil­la­ting of crystal­li­ne lat­ti­ce and for­ming of stan­ding wa­ves oc­cur, whi­le, ther­mal ca­pa­ci­ti­ve­ness and con­duc­tion of the ove­rall co­a­ting dec­re­a­ses. With its in­cre­a­sed oscil­la­ting, pho­nons re­le­a­se the ions cap­tu­red on and wit­hin elec­tro­des, and in­flu­en­ce the in­cre­a­se of ef­fi­ci­ency of ion con­duc­ti­vity.

Keywords: ion con­duc­ti­vity, Li-ion bat­te­ri­es, ul­trat­hin films, pho­nons, he­at ca­pa­city.
