“…Lithium ion batteries (LIBs) have become the most widely used power sources as the use of electric vehicles (EVs), portable devices, and uninterruptible power supplies (UPS) increases. The commercial carbonate-based electrolyte delivers good ionic conductivity around (10 –2 S/cm), resulting in fast lithium ion kinetics and good electrochemical performances. − Notwithstanding, carbonate-based electrolyte solutions, such as ethylmethyl carbonate (EMC), dimethyl carbonate (DMC), and ethylene carbonate (EC), have high flammability, high volatility, and low decomposition temperature, resulting in catastrophic explosions/fires under extreme conditions . The addition of flame-retardant solvents causes the performance decay of LIBs since they could intrinsically passivate the carbonaceous anodes …”

The solid-state electrolyte is a promising candidate to replace the liquid electrolytes in lithium ion batteries, although it has a fatal drawback of inferior ionic conductivity. Garnet-type LiLaZrO can be regarded as a favorable material for all-solid-state lithium batteries since it has better lithium ion kinetics, nonflammability, and outstanding electrochemical/thermal stability. The grain size is closely related to the microstructure, affecting the electrochemical and mechanical properties. Here, we control the grain size by adjusting the sintering time and demonstrate that Li6.1Ga0.3La3Zr2O12 (LGLZO) sintered at 1250 °C for 10 h delivers relative density of 97.5 ± 0.5%, hardness of 9.1 ± 0.46 GPa, ionic conductivities of 8.9 × 10–4 S/cm (Au/LGLZO/Au symmetric cell) and 4.2 × 10–5 S/cm (Li/LGLZO/Li symmetric cell), and critical current density of 0.58 mA/cm2, which are superior to those of LGLZO sintered for 20 h. Therefore, we can conclude that regulating sintering time is a simple and easy approach for high performance all-solid-state lithium ion batteries.
