Abstract
The behaviour, in different electrolyte, of Li during cycling in anode limited close packed cells has been studied. The highest efficiency (E) at a current density of 4 mA cm-2 and a charge density of 2 mA h cm-2 is obtained in LiAsF6 containing a mixture of THF/2-MeTHF with 2 vol.% 2MeF. The effect on E of current density and depth of discharge in ether solutions has also been examined. The charge of polarization resistance, ohmic drop in the solution and geometric capacitance with cycling, has been investigated by the galvanostatic pulse method. An assumption for the Li passivation observed during cycling in ether electrolytes is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
