Abstract: In this paper a new model of high-temperature superconductivity comprising all hitherto known aspects of a new type of oxygen superconductors has been described. This model presumes the existence of extremely strong electron-phonon coupling of "small bond polarons" which are generated by the motion of excess charge on the Cu(III) ions present in small amounts in the Cu(II)-O layers. In this case, the combination of the bound charges of the Jahn-Teller distortion gives rise to a very strong electron-phonon coupling which leads to the creation of the bipolaronic hole Copper pairs.
