Abstract
An anode-free solid-state battery may include a cathode layer; an anode current collector layer; and a separator layer between the cathode layer and the anode current collector layer. The battery can further include an anti-dendrite layer located between the separator layer and the anode current collector layer. The battery further includes an interfacial bonding layer located between the anti-dendrite layer and the anode current collector layer. The interfacial bonding layer increases an amount of electrical connectivity between the anode current collector layer. A first amount of adhesion between the interfacial bonding layer and the anode current collector layer can be greater than a second amount of adhesion between the anti-dendrite layer and the interfacial bonding layer.
