For electrolytes with conventional lithium salt concentration, it is not easy to generate sufficient anion‐derived beneficial inorganic components to stabilize the electrolyte‐lithium metal anode interface due to the repulsion of the free‐state anions by the anode. In this study, the above issues are solved through the strong interaction between electronegative materials and lithium ions (Li+). A...
Stable Li Metal Batteries
Ordered micro‐grooves are prepared by femtosecond laser on Cu foil for lithium metal battery. The deposition of Li can be directed by the micro‐grooves to form ordered and dense Li arrays. This idea for tuning lithium nucleation sites on current collector can significantly enlighten the future work for high‐energy‐density anode‐free full cells. More details can be found in...
Li metal anode is promising to achieve high‐energy‐density battery. However, it has rapid capacity fading due to the generation of inactive Li (dead Li), especially at high current density. This study reveals that the random distribution of Li nuclei leads to large uncertainty for the further growth behavior on Cu foil. Here, periodical regulation of Li nucleation sites on Cu foil by ordered lithiophilic...
