INCREASE OF MOBILITY OF IONS IN LI-ION BATTERIES BY ULTRATHIN PHONON COATINGS OF ELECTRODES

This pa-per pre-sents the re-sults of re-se-arch of behavior of pho-non sub-system in ul-trat-hin co-a-tings that are ap-plied on elec-tro-des in Li-ion bat-te-ri-es and that in-cre-a-se the ef-fi-ci-ency of ion tran-sport. Using the met-hod of Green fun-cti-ons it was de-mon-stra-ted that in ul-trat-hin films, in-cre-a-sed mec-ha-ni-cal oscil-la-ting of crystal-li-ne lat-ti-ce and for-ming of stan-ding wa-ves oc-cur, whi-le, ther-mal ca-pa-ci-ti-ve-ness and con-duc-tion of the ove-rall co-a-ting dec-re-a-ses. With their in-cre-a-sed oscil-la-ting, pho-nons re-le-a-se the ions cap-tu-red on and wit-hin elec-tro-des, and thus influence an in-cre-a-se in ef-fi-ci-ency of ion con-duc-ti-vity.
