Low-melting oxide glasses are promising as electrolytes for all-solid-state lithium rechargeable batteries. Glasses in the pseudobinary system Li 3 BO 3 Li 2 SO 4 were prepared by a mechanochemical technique. Raman spectra revealed that the glasses contained no macroanions which form networks but consisted only of Li + ions and two discrete ortho-oxoanions, BO 3 3¹ and SO 4 2¹. The density and molar volume increased and elastic moduli decreased with an increase in the Li 2 SO 4 content in the glasses. The heat treatment of the Li 3 BO 3 Li 2 SO 4 glasses at around 300°C brought about the crystallization to form ion conducting glassceramics. Electrical conductivities of the glasses and glass-ceramics in this system were maximized with the mixing of Li 3 BO 3 and Li 2 SO 4 . The conductivities were higher in the glass-ceramics of the compositions with small amounts of Li 2 SO 4 , ranging from 3 © 10 ¹6 to 1 © 10 ¹5 S cm ¹1 at room temperature, compared to the corresponding glasses. This conductivity enhancement by the heat treatment is probably due to the precipitation of solid solutions with a high temperature Li 3 BO 3 phase.

“…[13][14][15][16][17][18][19][20][21] In general, the specificity of the MM method enables the preparation of fine powders during room temperature and/or low-temperature thermal treatment. Such MM methods are adapted for the preparation of electrode and solid electrolyte materials for energy and sensor devices.…”

Triclinic LiTiOPO 4 fine powders were synthesized via low-temperature thermal treatment. First, amorphous fine powders were prepared by mechanical milling (MM) treatment of a mixture of the starting materials (Li 2 CO 3 , TiO 2 , and P 2 O 5 ) at room temperature. The mechanically milled amorphous powder formed a triclinic LiTiOPO 4 crystal below 700°C in air. The mechanically milled powders before heat treatment barely worked as an active material at ca. 0.1 C rate in the potential range of 1.0 to 3.0 V versus Li/Li + in lithium cells. On the other hand, the triclinic LiTiOPO 4 compounds obtained by the crystallization of the mechanically milled amorphous powders at 700°C in air worked as anode materials in lithium cells. The triclinic LiTiOPO 4 electrode materials exhibited capacities of around 100 mAh g −1. The average operation potential was around 1.7 V (vs. Li/Li + ). The triclinic LiTiOPO 4 pristine compound when used as an anode caused a phase transition into an orthorhombic compound during lithium insertion (charge process). The orthorhombic compound changed into a triclinic phase during lithium extraction (discharge process). The triclinic LiTiOPO 4 electrodes exhibited a good cycle performance in the potential range of 1.0 to 3.0 V versus Li/Li + . It is suggested that the crystalline phase changes reversibly during charge/discharge.

“…The thin film was deposited at 200°C on a Si substrate and a 90Li 3 BO 3 ·10-Li 2 SO 4 (mol%) electrolyte pellet. 15,16 The substrate temperature was chosen for improving characteristics of electrode-electrolyte interfaces based on a previous report. 17 To avoid exposure of the deposited film to the atmosphere, a PLD vacuum chamber connected to an Ar-filled grove box was used.…”
