Abstract
An electrode assembly for a secondary battery and method are provided. The electrode assembly comprises a population of unit cells and a constraint system. The electrode assembly comprises a population of electrode structures, a population of counter-electrode structures, and an electrically insulating separator material. The constraint system comprises (i) first and second primary growth constraints separated in the longitudinal direction, (ii) first and second connecting members separated in the vertical direction that connect the first and second primary growth constraints and a subset of the members of the electrode or counter-electrode population. The first and second connecting members are adhered to the subset by an electrically-insulating, thermoplastic, hot-melt adhesive having (i) a melting temperature in the range of 75° C. to 130° C., and (ii) a melt index value as measured according to ASTM D1238 in a range of at least 20 to no more than 350.
