(EN) Apparatus and method for compressing a stack of electrochemical cells
Abrégé
(EN) An electrochemical cell comprising a plurality of electrochemical cell components having at least one opening extending therethrough. At least one filament extends through the at least one opening and has two ends with first and second securing members coupled to the two ends. A biasing member is disposed to put the at least one filament in tension between the securing members and to put the plurality of electrochemical cell components in compression. The filament is preferably electronically insulating and preferably does not transmit torsional forces. The filament extends through the at least one opening at least one time and may loop around a securing member any number of times. The filament may have a finite cut length or may form a continuous filament loop.
