The electrochemical impedances of Li | Li symmetrical cells in EC/DEC electrolytes at 1.0 mA cm−2 were measured at the end of 1-, 100-, and 750-hour cycling. The results were analyzed through equivalent circuit model fitting to provide quantitative information (Fig. 4B and fig. S13), where the impedance spectra of Li metal | separator | Li metal cells can be decoupled to interfacial resistance and bulk resistance. The interfacial resistances of Li metal cells with LLZTO ion redistributors are much lower than those of cells with routine PP separators. They remain stable at around 90 ohms in 750-hour cycling, suggesting the inhibited Li dendrites and little electrolyte consumption. However, the interface resistances exhibit large fluctuations during cycling with routine PP separators. The interfacial resistance is as large as 226.7 ohms after cycling for 1 hour and then drops to 148.5 ohms after 100-hour cycling and soars to 793.6 ohms in 750 hours. The large fluctuations indicate unstable electrochemical environments during Li depositing and striping, where Li ions are not uniformly distributed.

These have included high pressure tanks, and dropping the temperature for cryogenic storage of liquid hydrogen. But these systems are complex to operate, and have potential safety risks.
The pair first joined Flight Engineer Nick Hague during the morning checking out space biology hardware and transferring more frozen research samples into Dragon’s science freezers. Hague and McClain then participated in regularly scheduled eye exams in the afternoon.

The long-term interfacial stabilities were further investigated through symmetrical Li metal | separator | Li metal cells based on ether- and carbonate-based electrolytes. During cycling, Li ions are transported back and forth between the two Li metal electrodes at a high current density of 1.0 mA cm−2. The voltage versus time plot is depicted in Fig. 4 (C and D). For a EC/DEC electrolyte system, the voltage hysteresis of Li | Li cells with routine PP separators (cyan line) is as large as 0.18 V, then diverges and goes beyond 0.30 V after 700-hour cycling, indicating that the electrolyte is nearly depleted resulting from the gradually accumulated Li dendrites and dead Li. In comparison, the cells with a LLZTO composite separator render a constant and stable voltage profile (80 mV) for 800 hours, suggesting a uniform Li metal electrode with a stable interface. A similar behavior can be observed in a DOL/DME electrolyte system (Fig. 4D). Compared with batteries with routine PP separators, the batteries with LLZTO layers render a tighter voltage hysteresis (73 mV versus >200 mV for the routine PP separator) and much more extended cycle life (75 hours versus <50 hours for the routine PP separator), indicating that the dendrites are controlled effectively.
