Abstract:
Various arrangements for creating a cylindrical anti-dendrite anode-free solid-state battery are presented. An anti-dendrite layer may be layered between an anode current collector layer and the cathode layer. A layered stack may be created that comprises a dry separator layer, a cathode layer layered with a cathode current collector layer, and the anti-dendrite layer layered with the anode current collector layer. The layered stack may be rolled into a cylindrical jelly roll. The rolled layered stack may be inserted into a pouch. A liquid electrolyte mixture may be added into the pouch. The liquid electrolyte mixture can permeate the dry separator layer. Heat can be applied to the pouch that causes the liquid electrolyte mixture to become a gel. The rolled layered stack can then be removed from the pouch and inserted into a cylindrical battery cell canister.
