“…6. As reported in the literature [12,25,26] this change is related to the loss of H 2 O incorporated into the crystal structure of the materials. Hashimoto et al [25] have concluded that the incorporation of water in as-prepared Ba 2 In 2 O 5 is due to the absorption of water from the atmosphere and that this process did not affect the crystal structure of the material.…”

“…Again, for the as-prepared BIO sample, an effect of water was noticed, in this case as a sharp increase in conductivity. When present, water in the structure is in interaction with the oxygen vacancies and oxygen ions [12,34]. When water is released, hydrogen incorporates directly and interacts with the free oxygen vacancies and ions, significantly improving conductivity.…”

“…When water is released, hydrogen incorporates directly and interacts with the free oxygen vacancies and ions, significantly improving conductivity. The mechanisms are suggested in the literature [12][13][14]34]. The decomposition or reduction of the material were excluded as possible causes for increased conductivity, as no changes in composition or structure were observed by XRD after the test in hydrogen.…”

“…One of the major approaches to achieve this goal involves searching for new electrolyte materials with a sufficiently high ionic conductivity in that temperature range. Proton-conducting ceramics attract significant attention due to their potential for proton conduction below 500 • C. Proton conduction in ceramic materials has been reported before [9][10][11][12]. Some doped perovskite-type oxides ABO 3 (e.g., BaCeO 3 , SrCrO 3 , SrZrO 3 ) and related brownmillerite-type oxides (e.g., Ba 2 In 2 O 5 ) have been reported to show mixed oxygen ion, electron and proton conduction, with predominant oxygen ion conduction at high temperatures (above 500 • C) and predominant protonic conduction at low temperatures (below 500 • C).…”

The mechanism of ions (oxygen or proton) incorporation in perovskite and brownmillerite ceramics in presence of oxygen, water vapour or hydrogen has been suggested elsewhere [11][12][13][14]. In general, the ion incorporation and the conductivity of these materials is due to the presence of oxygen vacancies, which are usually formed by doping the ideal perovskite A 2+ B 4+ O 3 2− with lower-valent metal M 3+ ions.…”

a b s t r a c tFive different compositions of brownmillerite materials, Ce-and La-doped, and undoped Ba 2 In 2 O 5 were synthesized via the solid-state reaction and the glycine-nitrate combustion process. Properties of the materials were characterized using XRD, HR-TEM, and TGA/DSC techniques. Conductivity measurements by AC impedance spectroscopy, performed in air and hydrogen-containing atmospheres, in the temperature range from 100• C to 500• C, were correlated to the properties of the materials and revealed the effects of dopant, microstructure, temperature and atmosphere on the total electrical conductivity of the materials. All compositions showed low conductivity in air. In hydrogen-containing atmospheres, while Ce-and La-doped Ba 2 In 2 O 5 showed low conductivity (4 × 10 −6 -3 × 10 −6 S cm −1 at 500 • C), undoped Ba 2 In 2 O 5 demonstrated a surprisingly high conductivity (between 0.02 S cm −1 and 0.7 S cm −1 in the temperature range from 300• C to 500• C), especially samples produced by the glycine-nitrate process. This finding creates potential opportunity for using Ba 2 In 2 O 5 as a proton-conductive material in intermediate temperature fuel cells.

Under low temperature (LT) conditions (−80 °C∼0 °C), lithium‐ion batteries (LIBs) may experience the formation of an extensive solid electrolyte interface (SEI), which can cause a series of detrimental effects such as Li+ deposition and irregular dendritic filament growth on the electrolyte surface. These issues ultimately lead to the degradation of the LT performance of LIBs. As a result, new electrode/electrolyte materials are necessary to address these challenges and enable the proper functioning of LIBs at LT. Given that most electrochemical reactions in lithium‐ion batteries occur at the electrode/electrolyte interface, finding solutions to mitigate the negative impact caused by SEI is crucial to improve the LT performance of LIBs. In this article, we analyze and summarize the recent studies on electrode and electrolyte materials for low temperature lithium‐ion batteries (LIBs). These materials include both metallic materials like tin, manganese, and cobalt, as well as non‐metallic materials such as graphite and graphene. Modified materials, such as those with nano or alloying characteristics, generally exhibit better properties than raw materials. For instance, Sn nanowire‐Si nanoparticles (SiNPs−In‐SnNWs) and tin dioxide carbon nanotubes (SnO2@CNT) have faster Li+ transport rates and higher reversible capacity at LT. However, it′s important to note that when operating under LT, the electrolyte may solidify, leading to difficulty in Li+ transmission. The compatibility between the electrolyte and electrode can affect the formation of the solid electrolyte interphase (SEI) and the stability of the electrode/electrolyte system. Therefore, a good electrode/electrolyte system is crucial for successful operation of LIBs at LT.
