The present invention provides a battery including an anode, a sulfur or composite sulfur material cathode, a separator and/or an electrolyte, and a modulation layer. The sulfur or composite sulfur cathode may be partially or fully prelithiated with a lithium composition comprised of lithium metal powder, a polymer binder compatible with the lithium metal powder and a rheology modifier compatible with the lithium metal powder. A modulation layer may be positioned between the prelithiation layer and the cathode. The modulation layer may be derived from a polymer material or may be a ceramic compound comprising a ceramic and a polymer.
