global concerns about the sustainability of LIBs, due to the rarity and uneven distribution of lithium on earth. [3] With this in mind, batteries employing earth-abundant elements as charge carriers with similar working principles, such as sodiumion batteries (SIBs) and potassium-ion batteries (PIBs), are promising as realistic alternatives for grid-level stationary applications. [4] As the critical component for rechargeable batteries, electrode materials play an important role in improving the energy density of the whole system, which can be realized by increasing the output voltage or capacity. [5] In recent years, since the emerging sodium and potassiumbased batteries have the potential to meet large-scale grid energy storage, intensive research have been devoted to this field, accompanied by significant progress. However, there is still considerable room for improvement regarding the electrode-active materials for SIBs and PIBs. This is because the accommodation of sodium or potassium in host materials is much more difficult than lithium ions, owing to their much larger ionic radii. [6] Their magnitude may cause severe pulverization of the electrode resulting from the distortions in the host lattice after repeated (de)intercalation and subsequently, a loss of contact between the active material and the current collector, resulting in the failure of the cell.During the past few decades, crystalline materials, as the primary electro-active species of choice in the battery field, have been thoroughly investigated. However, their synthesis can be time consuming, energy intensive, and costly. Besides, the storage capacity in crystalline materials is critically dependent on several factors including orientation of the crystallites, exposure of electrochemically active facets, phase transitions, and structural stability. [7] Generally, the charge storage mechanism of these kinds of material is based on guest ion insertion/extraction during the charge/discharge process. However, these host materials have limited ion channels for guest ions. As their counterpart, amorphous materials are intrinsically different in the arrangement of atomic clusters in the manner of short-range ordering, while these clusters are randomly linked with each other. [8] Hence, the amorphous state can be easily identified by conventional characterization technique such as no obvious diffraction peaks in powder X-ray diffraction (XRD). Owing to such long-range disordered and short-range ordered Room-temperature rechargeable sodium-ion batteries appear to be promising alternatives for grid and other storage applications to lithium-ion batteries because of the natural abundance, low cost, and environmental benignity of sodium. In response to the ever-increasing development for these technologies, an intensive exploration for appropriate electrode materials with high energy density is still underway. This Progress Report highlights the recent research in the investigation of amorphous materials, whose isotropic physical and chemical propertie...

“…9,10 We also demonstrated that 72SnO-28P 2 O 5 glass is a promising new anode active material that realizes high-energy-density LiBs [13][14][15] and NaBs. 16 Glass crystallization proceeds through two steps: nucleation and crystal growth. 17,18 In the development of new glass-ceramics, it is important to design the function (property), size, and morphology of crystals formed in the glassy matrix through the control of the nucleation and crystal growth.…”

In recent years, the expansion of demand for lithium ion batteries has resulted in soaring prices of the constituent resources. From the viewpoint of safety, studies on all‐solid‐state batteries are actively being carried out. In this study, we succeeded in driving all‐solid‐state batteries derived from nontoxic oxide glasses at room temperature without requiring scarce resources such as lithium and cobalt. The main structure of the ceramic batteries with a simple structure in which Na2FeP2O7 crystallized glass and β″‐alumina solid solution are joined by pressureless cofiring at 550°C. During the crystallization of Na2O‐Fe2O3‐P2O5 glass, fusion with the β″‐alumina solid solution is achieved. Reversible charge and discharge of 80 mAh/g were achieved at room temperature. It is not necessary to apply pressure during cell preparation or the use of the batteries. Furthermore, the strong junction at the cathode and electrolyte interface does not peel off during charge and discharge over a long period of 623 cycles. Ex situ X‐ray photoelectron spectroscopy revealed partial Fe4+ induction and a reversible charge and discharge reaction even after overcharging to 9 V. It was demonstrated that Na2FeP2O7 is very stable against overcharging to 9 V.

The crystallization behavior of bismuth borate glass in hydrogen argon mixed atmosphere was examined. When the 70B 2 O 3 30Bi 2 O 3 glass prepared by the melt quenching method was heat treated in a 5% hydrogen-95% argon atmosphere, spherical bismuth metal particles were formed in the glass matrix at 380°C, which is higher than glass transition temperature at 336°C and close to crystallization temperature at 399°C. As increase of heat treatment temperature, the diameter of bismuth grain was increased. Electrochemical activity of bismuth metal containing glass-ceramics was also evaluated as a negative electrode in lithium ion battery. Suppression of irreversible capacity at initial cycle due to lithium insertion was successfully performed by reductive heat treatment for crystallization of bismuth metal into glass matrix.
