    <subfield code="a">&lt;p&gt;The ageing mechanisms of C6/LiNi0.5Mn0.3Co0.2O2 batteries at various discharging currents and temperatures&lt;br&gt;
have systematically been investigated with electrochemical and post-mortem analyses. The irreversible capacity&lt;br&gt;
losses (&amp;Delta;Qir) at various ageing conditions are calculated on the basis of regularly determined electromotive force&lt;br&gt;
(EMF) curves. Two stages can be distinguished for the degradation of the storage capacity at 30 &amp;deg;C. The first stage&lt;br&gt;
includes SEI formation, cathode dissolution, etc. The second stage is related to battery polarization. The various&lt;br&gt;
degradation mechanisms of the individual electrodes have been distinguished by dVEMF/dQ vs Qout and dVEMF/dQ&lt;br&gt;
vs V plots. The Solid-Electrolyte-Interface (SEI) formation as well as the electrode degradation has been experimentally&lt;br&gt;
confirmed by XPS analyses. Both Ni and Mn elements are detected at the anode while Co is absent,&lt;br&gt;
indicating that the bonding of Co atoms is more robust in the cathode host structure. A Cathode-Electrolyte-&lt;br&gt;
Interface (CEI) layer is also detected at the cathode surface. The composition of the CEI layer includes Li salts,&lt;br&gt;
such as LiF, LiCOOR, as well as transition metal compounds like NiF2. Cathode dissolution is considered to be&lt;br&gt;
responsible for both the NiF2 detected at the cathode and Ni at the anode.&lt;/p&gt;</subfield>
