Abstract
Lithium button cells (1.5V) with thermally treated Bi2O3 cathodes (additive free), mainly of 11.4*3.4 mm standard size (100 mAh), have been constructed. They are characterized by high volumetric energy densities even at high discharge rate. The cell behaviour is also satisfactory after 1 year's storage, at low temperature (-10 °C) and under 500 μA pulses. Comparison with analogous Li cells (Li/FeS2 and Li/Pb2Bi2O5) or aqueous cells (Zn/HgO and Zn/Ag2O) confirms the usefulness of this system as a power source for microelectronic devices. This was also substantiated by field tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
