Abstract

An electrochemical battery having high energy per unit mass, and in particularly a lithium and thionyl chloride battery, comprising a stack (10) of positive and negative electrodes within a housing (2) closed by a cover (3), two metal terminals connected respectively to said positive electrodes and said negative electrodes passing through the stack and emerging from said cover, the battery being characterized by the fact that one of said terminals (24) is in the form of a hermetically closed tube (30) lined internally with a capillary structure, filled with a heat-conveying fluid, and passing through the bottom (7) of said housing to be in contact with a cooling means (33), said terminal thus constituting a heat pipe for said battery.
