The invention relates to dimension constraint of a three-dimensional battery. A secondary battery that cycles between a charged state and a discharged state is provided that includes a battery housing, an electrode assembly within the battery housing, carrier ions, a non-aqueous liquid electrolyte, and a set of electrode constrains. The set of electrode constrains includes a primary constraining system having first and second primary growth constrains separated from each other in the longitudinal direction, where the primary constraining array constrains growth of the electrode assembly in the longitudinal direction, and at least one primary connecting member connecting the first and second primary growth constrains to the first and second primary growth constrains. The secondary battery is such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction during 20 consecutive cycles of the secondary battery is less than 20%. The set of electrode constrains also includes a s
