“…[ 61 ] A final study evaluating current collector substrates for anode‐free full cells was published in 2019 by Pande and Viswanathan. [ 62 ] By computationally screening candidates for reduced activation barriers for nucleation of lithium metal and surface diffusion of lithium atoms, the authors found several lithium alloy substrates that could help form compact and dense deposits of lithium. This would feasibly allow for enhanced electrochemical performance for an extended number of cycles, even at high charge rates.…”

The development of high‐energy density batteries is critical to the decarbonization of the transportation and power generation sectors. For any given lithium‐containing cathode system, the anode‐free full cell configuration, which eliminates excess lithium and pairs the fully lithiated cathode with a bare current collector, can deliver the maximum possible energy density. The absence of free lithium metal during cell assembly confers significant practical advantages as well. It is also the ideal framework for developing a thorough understanding of lithium deposition in conjunction with various cathode systems. However, the poor efficiencies of lithium plating and stripping lead to rapid lithium inventory loss and poor cycle life. In the last few years, multiple studies have demonstrated the application of advanced electrolytes, modified current collectors, and optimized formation and cycling parameters to stabilize lithium deposition and improve cycle life (80% capacity retention) to 100 cycles and beyond. This review provides an overview of the various strategies toward sustaining lithium inventory in anode‐free full cells and summarizes the work undertaken in this nascent field. It is expected that further improvement upon these strategies and a combinatorial approach can enable cycle lives far in excess of what has been achieved so far.

“…[21,22] Another possibility is the use of other current collectors more compatible with Li. [23] As the use of Cu is inherited from LIB designs, other metals or alloys can provide better compatibility with Li metal deposition. Distinct from surface modification of the current collector, some works report the use of Li metal hosts or artificial SEI layers.…”

“Anode‐free” lithium metal batteries are cells that have no excess lithium metal. They have become a topic of tremendous attention, mostly driven by recent progress and interest in practical batteries with Li metal anodes. These cells are expected to provide improved performance. However, a deeper analysis on the potential manufacturing costs have not been weighed against the cell attributes. Specifically, the increased energy density and gravimetric energy density of anode‐free cells versus their reduced cycle life when compared with standard lithium‐ion batteries (LIB). In this perspective, a multifaceted comparison between anode‐free batteries with current LIB and future Li metal‐based batteries is shown. Furthermore, not only an overview of the research strategies on the anode‐free design is provided but also attempted to estimate the potential advantages weighed in different scenarios considering cost, performance, processing, and technology maturity.

The oxygen evolution reaction (OER) limits the performance of protonexchange membrane electrolyzers since substantial overpotentials of several hundred millivolts are required for the formation of gaseous oxygen at the anode to reach satisfying current densities. Theoreticians trace this to the occurrence of a linear scaling relationship between the OH and OOH adsorbates within the electrocatalytic OER cycle, which thermodynamically restrains this four-electron process. While commonly the breaking of this particular scaling relation is pursued as a promising strategy to enhance catalytic turnover, the present progress report summarizes recent trends in the screening of electrode materials for the OER aside this notion. This contains an extension of thermodynamic-based screening methods by including the kinetics, applied overpotential, and the electrochemical-step symmetry index into the analysis, enabling material screening within a unifying methodology, or material screening by molecular orbital principles and band theories. The combination of activity-based screening methods with a proper assessment of catalyst stability may aid the further search of electrode materials for the OER in the future.
