In addition, LIBs still suffer from high cost, limited durability, and poor safety. [3] As a consequence, an alternative rechargeable battery system is crucial to cope with the growing demands of electric vehicles. [4] The prior demand for a power battery is security. The conventional power batteries suffered from frequent combustion accidents. The ascending voltage of cathodes will lead to stability concerns. Most of the thermal runaway is triggered by the reaction derived from electrodes. [6] The decomposition of cathode materials releases heat and oxygen and will trigger the combustion of flammable organic electrolytes. However, the high-energy cathode is essential for an energy-dense battery. Hence the substitution of conventional organic electrolytes is feasible to both enhance the energy density and battery safety. [5,7] The replacement of organic liquid electrolytes (OLEs) with solid-state electrolytes (SSEs) provides a promising future for the large-scale application of lithium metal batteries (LMBs). SSEs with wide electrochemical stability windows and high modulus possess the potential to enable high-capacity electrode materials and prevent Li dendritic deposition. [8] Besides, the SSEs also possess good thermal stability, which enables a wide operation temperature range and avoid the combustion risk. The introduction of SSEs allows a simplified battery design and minimization of inactive materials, consequently increasing energy density at the cell-level. Moreover, the solid-state electrolytes enable the employment of Li metal anodes, which is considered as the most promising anode for next-generation rechargeable batteries due to its ultrahigh theoretical specific capacity of 3860 mAh g −1 and lowest negative electrochemical potential (−3.04 V vs the standard hydrogen electrode). [9] In conventional organic electrolytes, lithium metal suffers from the unstable solid-state interphase, dendrite penetration, and pulverization issues. [1c,10] The rapid deterioration of LMBs is attributed to the high reactivity of lithium metal. [11] Virtually most conventional OLEs can be reduced at the Li surface, forming unstable solid electrolyte interphase (SEI). During repeated charge-discharge cycles, Li tends to generate dendritic morphology because of nonuniform current/ion distribution. [12] Lithium dendrites normally lead to the fracture and regeneration of SEI, further aggravating the dendrite growth. [12a,13] The The scale-up process of solid-state lithium metal batteries is of great importance in the context of improving the safety and energy density of battery systems. Replacing the conventional organic liquid electrolytes (OLEs) with solid-state electrolytes (SSEs) opens a new path for addressing increasing energy demands. Advanced approaches have been validated in lab-scale cells, but only a few successful results can be applied on the practical scale. Herein, the battery systems enabled by SSEs are briefly reviewed and the difficulties and challenges for both lab-level cells and large-scale batteries from...

In this study, we prepared a free‐standing ultra‐high dispersion sulfur three‐dimensional graphene (S‐3DG) foam by a simple in‐situ synthesis method. The HRTEM and SAED test of the discharged and charged products showed reversible conversion of Li2S and S during cycling. All‐solid‐state Li−S batteries with 55% sulfur content can reach initial discharge capacity of 1680 mAh g−1 at 1/16 C and 410 mAh g−1 at 4 C. And the capacity was about 450 mAh g−1 after 20 times cycling tested at 1/8 C. Moreover, Li−S batteries with 80% sulfur loading (8 mg/cm2) exhibited a superior cell‐level energy density of 588.8 Wh kg−1.

“…With a rGO@S–Li 10 GeP 2 S 12 –acetylene black composite, a capacity of 903 mAh g −1 was obtained at 1C at 60 °C, which was maintained at 830 mAh g −1 after 750 cycles [487]. Most of all, Li 7 P 3 S 11 glass-ceramic solid electrolyte with a high ionic conductivity and a composite cathode made of sulfur and BP2000 porous carbon (S@BP2000) with a core-shell structure were used to fabricate a novel all-solid-state sulfur battery [488]. Owing to the ionic conductivity of Li 7 P 3 S 11 (2 × 10 −3 S cm −1 at room temperature, the cell delivered a capacity of 1391 mAh g −1 at 0.2C and 677 mAh g −1 at 5C, and a capacity retention of nearly 100% after 1200 cycles was obtained, for a mass loading of the cathode of 2 mg cm −2 .…”

Building Better Batteries in the Solid State: A Review

et al. 2019

View full text Add to dashboard Cite

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.
