Lc is the minimum Li dendrite length before the Li dendrite becomes stable and begins to grow, which is the critical Li dendrite length for further growth. γ represents the interfacial energy required to form a new Li/SEI interface per unit surface area. σ is the stress at the tip of the crack or grain boundary, which is mainly determined by the external current. E is the bulk modulus. This critical Li dendrite length is similar to the critical radius in homogeneous and heterogeneous nucleation processes (33). Once the dendrite length is larger than the critical length, the dendrite can grow without any additional energy input, which means that the dendrite can grow spontaneously (fig. S9). Therefore, the critical length (fig. S9) can be used to evaluate the ability of SEI to suppress the Li dendrite growth. The larger Lc means higher Li dendrite suppression ability of SEI.

The market for refinery catalysts in the oil refining sector at $4,967 million in 2016 is Expected To Be Worth $6,490 Million By 2023, growing at 3.8% on average between 2017 and 2023. There are 500 FCC units being operated globally, each of which requires a constant supply of FCC catalysts. There are 3,000 HPC units being operated globally, or a capacity of approximately 44 million barrels per day, each of which typically requires replacement HPC catalysts once every one to four years.

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.

Construction is ongoing at their Kwinana lithium hydroxide plant in Western Australia, and is expected to be finished in late 2018.
