摘要
An electrolyte structure for a battery cell with a lithium metal anode has a first side configured to contact the anode and a second side facing opposite the first side. The electrolyte structure includes a first region that is adjacent to the first side and extends towards the second side and a second region disposed between the first region and the second side. The first region has a first composition of materials that is electronically insulating such that the electrolyte is stable against the lithium metal anode. The second region has a second composition of materials that is different than the first composition and has typical electrolyte properties such as mechanical strength, stability against a cathode, and ionic conductivity. The first region and the second region define a compositional gradient across a thickness of the electrolyte structure. The compositional gradient is continuum-fabricated at one point via a gradient growth method.
