Lithium batteries - Secondary systems – All-solid state systems | Negative electrode – “Anode-free”

In this chapter, the role of metal anodes in future solid-state batteries is discussed, which have the potential to significantly advance short-term energy storage by increasing energy density, safety, and manufacturability. Further, the concept of "anode-free" secondary lithium metal batteries is analyzed in detail regarding potential advantages and challenges. This design allows a cell to be assembled without the need for a lithium metal reservoir, as the anode active material is deposited onto the current collector within the initial charging step. Different strategies to achieve "anode-free" cell operation are discussed with regard to their individual merits. By examining these concepts and their interconnectedness, further research is needed to pave the way for more sustainable and effective energy storage solutions.
