A solid-state battery and methods of making the same are disclosed. The battery includes a plurality of cells and first and second terminals on opposite sides/edges of the battery. Each cell includes a cathode current collector (CCC), a cathode thereon, a solid-state electrolyte, an anode current collector (ACC), a moat in the cathode and the electrolyte and around the ACC, a barrier/insulation film, a via/opening in the barrier/insulation film exposing the ACC, and a conductive redistribution layer in the via/opening, in the moat, on the barrier/insulation film, and on a first sidewall of each cell. The barrier/insulation film encapsulates the CCC, the cathode, the solid-state electrolyte and the ACC. One terminal is electrically connected to each ACC through the redistribution layer, and the other is electrically connected to each cathode or CCC.
