Highly conductive glass-ceramic electrolytes are successfully prepared in the system Li 2 S - P 2 S 5 with 70 and 80 mol% Li 2 S . The conductivities of these electrolytes are respectively 3.2 × 10-3 and 1.0 × 10-3 S cm -1 at room temperature. The precipitated crystals upon heat treatment of the glass are new superionic phase Li 7 P 3 S 11 and thio-LISICON II analog Li 3+5x P 1-x S 4, respectively. The crystal structure of the new phase Li 7 P 3 S 11 is analyzed and found to have a triclinic unit cell with space group of P-1 and to contain [Formula: see text] and [Formula: see text] ions. All-solid-state batteries using the Li 2 S - P 2 S 5 glass-ceramics are fabricated in order to evaluate the cell performance as a lithium secondary battery. The cells In /80 Li 2 S ·20 P 2 S 5 (mol%) glass-ceramic/ LiCoO 2 exhibit excellent cycling performance of over 500 times with no decrease in the discharge capacity (100 mAh g-1) at limited current densities. They also worked under very high current densities of 10 mA cm-2 when oxide- or sulfide-coated LiCoO 2 particles were used as an active material.

ABSTRACTHighly ion-conductive Li6PS5Cl Li-argyrodites were prepared through a high energy ball milling. Electrical and electrochemical properties were investigated. Ball-milled compounds exhibit a high conductivity of 1.33×10−4 S/cm with an activation energy of 0.3-0.4 eV and an electrochemical stability up to 7V vs. lithium. These results are obtained after only 10 hours of milling and with no additional heat treatment.To validate the use of the Li6PS5Cl-based solid electrolyte, all-solid-state batteries using LiCoO2 and Li4Ti5O12 as active material have been realized. The optimization of the electrode composition led to a maximum of 46 and 27 mAh per gram of composite for LiCoO2 and Li4Ti5O12-based half-cells respectively. The assembled all-solid-state LiCoO2 / Li6PS5Cl / Li4Ti5O12 battery presents a sustainable reversible capacity of 27 mAh per gram of active material and a coulomb efficiency close to 99%.

Measures to improve the cycling performance and stability of bulk-type all-solid-state batteries (SSBs) are currently being developed with the goal of substituting conventional Li-ion battery (LIB) technology. As known from liquid electrolyte based LIBs, layered oxide cathode materials undergo volume changes upon (de)lithiation, causing mechanical degradation due to particle fracture, among others. Unlike solid electrolytes, liquid electrolytes are somewhat capable of accommodating morphological changes. In SSBs, the rigidity of the materials used typically leads to adverse contact loss at the interfaces of cathode material and solid electrolyte during cycling. Hence, designing zero- or low-strain electrode materials for application in next-generation SSBs is desirable. In the present work, we report on novel Co-rich NCMs, NCM361 (60% Co) and NCM271 (70% Co), showing minor volume changes up to 4.5 V vs Li<sup>+</sup>/Li, as determined by <i>operando</i> X-ray diffraction and pressure measurements of LIB pouch and pelletized SSB cells, respectively. Both cathode materials exhibit good cycling performance when incorporated into SSB cells using argyrodite Li<sub>6</sub>PS<sub>5</sub>Cl solid electrolyte, albeit their morphology and secondary particle size have not yet been optimized.
