ELECTROCHEMICAL CELLS AND THEIR USE

摘要

Electrochemical cells containing (A) at least one cathode which has at least one lithiated Mn-containing compound which has an Mn content of from 60 to 80 mol%, based on transition metal present in the cathode (A), (B) at least one anode which comprises carbon in an electrically conductive modification, (C) at least one electrolyte which contains a) at least one aprotic organic solvent, (b) at least one lithium salt and (c) at least one organic compound which has at least one Si-N single bond per molecule.
