1. In a vibration resistant electrochemical cell including an electrode assembly of spirally wound plate electrodes having at least one end terminating among the outer convolutions of the electrode assembly, and further having internal terminal connections at predetermined locations relative to said end the improvement comprising the combination of:

  • radially asymmetric external terminals associated with said internal terminal connections, anda tubular case of deformable material receiving said electrode assembly and having inwardly directed deformed wall portions firmly engaging said electrode assembly and restraining it against movement within the case,said external terminals having a fixed circumferential orientation relative to said case so that said deformed wall portions are displaced from said electrode terminal and by a known amount sufficient to avoid the exertion of damaging mechanical stress upon the assembly at said terminal end.
