What are the ionic conductivities of SN-LiTFSI?

The ionic conductivities of SN-LiTFSI, dense LAGP pellet and LAGP/SN hybrid electrolyte are 3.57 × 10 −3 S•cm –1, 1.96 × 10 −4 S•cm –1 and 1.17 × 10 −3 S•cm −1 at 30°C, respectively. And the corresponding activation energy (Ea) based on the Arrhenius plots for these three electrolytes are 0.27 eV, 0.40 eV and 0.29 eV, respectively.

What is the discharge capacity of SSLB?

As shown in Fig. 6 b, the SSLB also shows a decent high-rate performance. The discharge capacities are 175.2, 156.4, 131.9, and 107.5 mAh•g −1 at 0.1C, 0.2C, 0.5C, and 1C, respectively (1C=180 mA•g −1). When the rate is restored to 0.2C, the specific capacity quickly returns to 165.0 mAh•g −1.

What is the ionic conductivity of lagp/SN hybrid electrolyte?

Due to the structural design, LAGP/SN hybrid electrolyte displays high ionic conductivity of 1.17 × 10 −3 S•cm –1 at 30°C, superior Li + transference number (0.77), and wide electrochemical window (0∼5.0 V vs. Li + /Li).

Are ncm523/li sslbs effective at room temperature?

The NCM523/Li SSLBs with LAGP/SN hybrid electrolyte show excellent rate (1C) and cycling performance at room temperature, which deliver a specific capacity of 153.8 mAh•g−1 with a capacity retention of 90.0% after 100 cycles at 0.2C. Moreover, pouch cells demonstrate the scale-up potential application of high-energy-density SSLBs.

Which adsorption energy is better SN vs a commercial separator?

ETPTA monomers. The adsorption energy of SN investigated by DFT calculation indicates the infiltration and the affinity of LAGP are better than that of the commercial separator. The electrochemical properties are greatly enhanced owing to the structural design.
