“…, and Li-O-C. [28][29][30][31] TOF-SIMS was performed on the disk after immersion in LP30 for 150 h (Figure S9) ZrO À fragments were detected with a relatively low intensity at the surface of the disk after 150 h of exposure; the intensity of ZrO À is indicative of the relative concentration of LLZTO. In agreement with the XPS results, LiF À and LiCO 3 À fragments show relatively high intensities close to the disk surface, confirming the presence of an SEI rich in LiF and Li 2 CO 3 .…”

An advantageous solid electrolyte/liquid electrolyte interface is crucial for the implementation of a protected lithium anode in liquid electrolyte cells. Li 6.5 La 3 Zr 1.5 Ta 0.5 O 12 (LLZTO) garnet electrolytes are among the few solid electrolytes that are stable in contact with lithium metal. We show LLZTO is unstable in contact with the organic carbonate-based Li + liquid electrolyte used in conventional Li-ion cells. The interfacial resistance between LLZTO and LiPF 6 in (CH 2 O) 2 CO: OC(OCH 3 ) 2 (1:1 v/v) increases with time due to the growth of a lithium-ion-conducting solid electrolyte interphase (SEI) at the surface of the ceramic electrolyte. The interphase is composed of Li 2 CO 3 , LiF, Li 2 O, and organic carbonates. Even at a rate of 5 mA cm À2 , a 3 V potential drop occurs across the LLZTO/liquid electrolyte interface. A practical LLZTO membrane (thickness $10 mm), in contact with a lithium anode, gives a potential loss of $16 mV, less than 1% of the resistance of the SEI.

“…Later, Zhou and co‐workers reported a series of good works by application of glass‐ceramic electrolytes, such as Li 1+ x Al y Ge 2− y (PO 4 ) 3 (LAGP), Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP), and Li 1+ x + y Al x (Ti,Ge) 2− x Si y P 3− y O 12 (LATGP) . More recently, Cui and co‐workers reported the fabrication of solid‐state Li–air battery using garnet‐type Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZO) ceramic electrolyte and a composite cathode consisting of active carbon, LLZO powder, and Li salt . Compared with organic liquid electrolytes, these solid ceramic electrolytes are thermally stable, nonflammable, and less reactive with the electrode materials .…”

Gel-polymer electrolytes are considered as a promising candidate for replacing the liquid electrolytes to address the safety concerns in Li-O /air batteries. In this work, by taking advantage of the hydrogen bond between thermoplastic polyurethane and aerogel SiO in gel polymer, a highly crosslinked quasi-solid electrolyte (FST-GPE) with multifeatures of high ionic conductivity, high mechanical flexibility, favorable flame resistance, and excellent Li dendrite impermeability is developed. The resulting gel-polymer Li-O /air batteries possess high reaction kinetics and stabilities due to the unique electrode-electrolyte interface and fast O diffusion in cathode, which can achieve up to 250 discharge-charge cycles (over 1000 h) in oxygen gas. Under ambient air atmosphere, excellent performances are observed for coin-type cells over 20 days and for prototype cells working under extreme bending conditions. Moreover, the FST-GPE electrolyte also exhibits durability to protect against fire, dendritic Li, and H O attack, demonstrating great potential for the design of practical Li-O /air batteries.

“…Ceramics combine strong mechanical stiffness with high lithium transference numbers but must be combined with polymers to avoid large solid–solid interfacial resistances and fast formation of dendrites on the anode. Such solid electrolytes, including polymer and ceramic electrolytes, are known to be competitive alternatives to liquid electrolytes in Li-O 2 batteries and improve battery safety [397,398,399]. Several reasons can be provided for this observation.…”

Building Better Batteries in the Solid State: A Review

Most of the current commercialized lithium batteries employ liquid electrolytes, despite their vulnerability to battery fire hazards, because they avoid the formation of dendrites on the anode side, which is commonly encountered in solid-state batteries. In a review two years ago, we focused on the challenges and issues facing lithium metal for solid-state rechargeable batteries, pointed to the progress made in addressing this drawback, and concluded that a situation could be envisioned where solid-state batteries would again win over liquid batteries for different applications in the near future. However, an additional drawback of solid-state batteries is the lower ionic conductivity of the electrolyte. Therefore, extensive research efforts have been invested in the last few years to overcome this problem, the reward of which has been significant progress. It is the purpose of this review to report these recent works and the state of the art on solid electrolytes. In addition to solid electrolytes stricto sensu, there are other electrolytes that are mainly solids, but with some added liquid. In some cases, the amount of liquid added is only on the microliter scale; the addition of liquid is aimed at only improving the contact between a solid-state electrolyte and an electrode, for instance. In some other cases, the amount of liquid is larger, as in the case of gel polymers. It is also an acceptable solution if the amount of liquid is small enough to maintain the safety of the cell; such cases are also considered in this review. Different chemistries are examined, including not only Li-air, Li–O2, and Li–S, but also sodium-ion batteries, which are also subject to intensive research. The challenges toward commercialization are also considered.
