Abstract: A one-step and dry process for forming a high first cycle efficiency anode is provided. The process may include dry mixing an active component having an active anode material, a binder and a conductive material with a prelithiation agent to form a dry anode material mixture. The prelithiating agent may be a printable lithium composition and may include a lithium metal powder, a polymer binder compatible with the lithium metal powder, and a rheology modifier compatible with the lithium metal powder. The prelithiation agent may also be a solvent-free stabilized lithium metal powder. The dry anode material mixture is applied to a substrate as a non self-supporting layer to form the electrode which may be used in a wide variety of batteries including lithium ion batteries, lithium ion capacitors and solid-state batteries.
