Abstract
The behaviour of the Li/Li1+xV3O8 system in a secondary button cell has been investigated. it is shown that when using electrolytes based on LiAsF6 (without stabilizing additives) the best result are achieved with cyclic esters. It is established that the charging conditions influence significantly the cell cyclability, while the discharge conditions have a limited effect. It is also demonstrated that mixtures of ethylene and propylene carbonate lead to a considerably better reversibility of the system. A satisfactory electrode performance has been obtained: 180 Ahkg-1 at the 100th cycle for the positive electrode material and over 95% utilization of the Li electrodeI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
