Balancing Polysulfide Distribution in "Anode-Free" Lithium-Sulfide Batteries.

ABSTRACT: Lithium-sulfide positive electrodes represent a promising alternative to established transition metal-based positive electrodes due to enhanced specific capacity and sustainability. While positive electrodes containing elemental sulfur require a lithiated negative electrode, lithium-sulfide can serve as the lithium reservoir and thus be paired with bare copper electrodes in "anode-free" or "zero-excess" cell concepts. This boosts energy density and avoids handling of thin lithium metal electrodes. While promising electrochemical performance of "anode-free" lithium-sulfide batteries has already been demonstrated, many reported cell configurations rely on nickel- instead of copper-based negative electrodes, undermining the enhanced sustainability bestowed by lithium-sulfide positive electrod
