NICHTWAESSRIGELEKTROLYTBATTERIE VOM ELLIPTISCHEN SAEULENTYP

摘要

The present invention provides an elliptical column type, non-aqueous electrolyte battery, comprising an elliptical column type spiral electrode assembly formed by winding positive (14) and negative (12) electrode plates through a separator (13) and a resilient member (11) positioned at the centre of the electrode assembly and normally expanding the electrode assembly from the centre in outward directions of larger and smaller radius portions. The positive electrode plates may comprise manganese dioxide, carbon fluoride or silver chromate and the negative electrode plate may comprise lithium or sodium.
