Abstract

See full text

System and method of manufacturing high-strength bonded metal sheets for a battery cell are provided. The method comprises providing a stackup comprising a first metal sheet and a second metal sheet. The first and second metal sheets are separated by a first coating layer. The first coating layer comprises nickel-phosphide. The first metal sheet includes a first material of a first melting point and the second metal sheet includes a second material of a second melting point. The first coating layer including a third material of a third melting point. The method further comprises heating the stackup to allow crystallization of nickel in the first coating layer and remove the residual nickel-phosphide defining an enhanced coating layer. The enhanced coating layer comprises crystallized nickel for high-strength solid state bonding of the first and second metal sheets to the enhanced coating layer.
