“…An all-solid-state In/LiCoO2 or Li-In/Li4Ti5O12 cell with Li2S-P2S5 glass-ceramic electrolytes exhibits good cycle performance for hundreds of times at 25°C (Tatsumisago and Hayashi, 2008;Tatsumisago et al, 2013). These cells operate at a high temperature of 100°C, where it is difficult for a liquid electrolyte cell to be used.…”

All-solid-state batteries with inorganic solid electrolytes (SEs) are recognized as an ultimate goal of rechargeable batteries because of their high safety, versatile geometry, and good cycle life. Compared with thin-film batteries, increasing the reversible capacity of bulk-type all-solid-state batteries using electrode active material particles is difficult because contact areas at solid-solid interfaces between the electrode and electrolyte particles are limited. Sulfide SEs have several advantages of high conductivity, wide electrochemical window, and appropriate mechanical properties, such as formability, processability, and elastic modulus. Sulfide electrolyte with Li7P3S11 crystal has a high Li + ion conductivity of 1.7 × 10 −2 S cm −1 at 25°C. It is far beyond the Li + ion conductivity of conventional organic liquid electrolytes. The Na + ion conductivity of 7.4 × 10 −4 S cmis achieved for Na3.06P0.94Si0.06S4 with cubic structure. Moreover, formation of favorable solid-solid interfaces between electrode and electrolyte is important for realizing solid-state batteries. Sulfide electrolytes have better formability than oxide electrolytes. Consequently, a dense electrolyte separator and closely attached interfaces with active material particles are achieved via "room-temperature sintering" of sulfides merely by cold pressing without heat treatment. Elastic moduli for sulfide electrolytes are smaller than that of oxide electrolytes, and Na2S-P2S5 glass electrolytes have smaller Young's modulus than Li2S-P2S5 electrolytes. Cross-sectional SEM observations for a positive electrode layer reveal that sulfide electrolyte coating on active material particles increases interface areas even with a minimum volume of electrolyte, indicating that the energy density of bulk-type solid-state batteries is enhanced. Both surface coating of electrode particles and preparation of nanocomposite are effective for increasing the reversible capacity of the batteries. Our approaches to form solid-solid interfaces are demonstrated.

“…We have investigated electrochemical performances of bulk-type all-solid-state cells using LiCoO 2 electrodes and Li 2 S-P 2 S 5 solid electrolytes. [1][2][3] A selection of electrode active materials is one of the most important factors to improve battery performances. LiNi 1/3 Mn 1/3 Co 1/3 O 2 (NMC) has been first developed by Ohzuku and Makiura as an advanced positive electrode material which is alternative to LiCoO 2 .…”

Raman spectroscopy was conducted for LiNi 1/3 Mn 1/3 Co 1/3 O 2 (NMC) composite positive electrodes in all-solid-state batteries using Li 2 S-P 2 S 5 solid electrolytes. Raman spectral changes attributable to structural changes of NMC were observed during the initial charge-discharge test. To evaluate state-of-charge (SOC) distributions in the NMC electrodes, Raman mapping was carried out for the electrodes of charged and discharged cells. The mapping images indicated that most NMC particles were uniformly delithiated and lithiated by the charge-discharge process. It is noteworthy that uniform charge-discharge reactions proceeded in the NMC electrodes.

Innovative rechargeable batteries that can effectively store renewable energy, such as solar and wind power, urgently need to be developed to reduce greenhouse gas emissions. All-solid-state batteries with inorganic solid electrolytes and electrodes are promising power sources for a wide range of applications because of their safety, long-cycle lives and versatile geometries. Rechargeable sodium batteries are more suitable than lithium-ion batteries, because they use abundant and ubiquitous sodium sources. solid electrolytes are critical for realizing allsolid-state sodium batteries. Here we show that stabilization of a high-temperature phase by crystallization from the glassy state dramatically enhances the na + ion conductivity. An ambient temperature conductivity of over 10 − 4 s cm − 1 was obtained in a glass-ceramic electrolyte, in which a cubic na 3 Ps 4 crystal with superionic conductivity was first realized. All-solid-state sodium batteries, with a powder-compressed na 3 Ps 4 electrolyte, functioned as a rechargeable battery at room temperature.
