“…Currently, sodium − sulphur (NAS) batteries 5 are used for large-scale storage, because they have high energy densities of up to 760 Wh kg − 1 . However, NAS batteries need to be operated at temperatures up to 300 °C to use liquid-state sulphur-positive electrodes and sodiumnegative electrodes and to enhance the conductivity of β-alumina solid electrolyte, a well-known Na + ion conductor.…”

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.

The present work discusses results of preliminary tests concerning the technology of continuous dosage of sodium to a metallic bath from the aspect of modification of EN AC-44200 alloy, through the use of a multiple compound (salt) of sodium. The technology consists in continuous electrolysis of sodium salts occurring directly in a crucible with liquid alloy. As a measure of the degree of alloy modification over the course of testing, the ultimate tensile strength (UTS or Rm) and analysis of microstructure are taken, which confirm the obtained effects of the modification on the investigated alloy. Assurance of stable parameters during the process of continuous modification with sodium, taking into consideration the fact of complex physical-chemical phenomena, requires additional tests aimed at their optimization and determination of a possibility of implementation of such technology in metallurgical processes.

“…Ceramicbased solid electrolytes provide an edge with a high level of security, since ceramic is resistant to high temperatures and less reactive to lithium. Ceramics used for the solid electrolyte generally has a framework structure or a layered structure that allows for the easy mobility of ions [3,4]. Ceramic solid electrolyte system will be composed of a ceramic matrix composite with inorganic materials such as lithium salt as a dopant or filler.…”

Compositesof montmorillonite (MMT) -lithium salts have been prepared using a simple process of powders mixing followed by heating. The powders resulting from this method are expected to beionic conductors with a high ionic conductivity characteristics. This characteristics is also further improved by employing gamma-ray irradiation technique at specified irradiation doses. The best results were obtained for the (LiCl)0.5(MMT)0.5 composite with a room temperature ionic conductivity of 2.192 mS/cm, which then increases to ~5 mS/cm after gamma irradiation at a dose of 400 kGy. This value is equivalent to the value of the ionic conductivity of current commercial rechargeable lithium battery, which is ~10 mS/cm. However the commercial battery system is still employing an unsafe organic electrolyte. By employing this lightweight,inexpensive and high-temperature resistant ceramic montmorillonite, the final result of this Research and Development workt is expected to provide an alternative solid electrolyte system for rechargeable battery which is safer and more inexpensive especially for secondary battery technology development in Indonesia. AbstrakDampak Suhu Panas dan Iradiasi Sinar - -pada Konduktivitas Ion (LiCl)x(Montmorillonite)1-x. Pembuatan bahan elektrolit padat dilakukan dengan proses sederhana berupa pencampuran serbuk yang diikuti dengan pemanasan yang diharapkan dapat membentuk komposit montmorillonite (MMT)-garam Litium yang memiliki karakteristik konduktivitas ionik yang tinggi. Karakteristik ini juga dicoba ditingkatkan lebih jauh dengan menggunakan iradiasi sinar gamma dengan pengaturan dosis radiasi. Hasil terbaik diperoleh untuk komposit (LiCl)0.5(MMT)0.5 dengan nilai konduktivitas ionik pada suhu ruang mencapai 2,192 mS/cm yang meningkat menjadi ~5 mS/cm setelah iradiasi gamma dengan dosis 400 kGy. Nilai ini seorde dengan nilai konduktivitas ionik baterai isi ulang yang ada saat ini yang bernilai ~10 mS/cm namun masih menggunakan elektrolit organik yang kurang aman. Dengan penggunaan keramik montmorillonite yang ringan, murah serta memiliki kemampuan untuk bertahan pada kondisi suhu tinggi, hasil dari litbang ini diharapkan memberikan prospek salah satu alternatif sistem elektrolit padat baterai isi ulang yang aman dan ekonomis terutama untuk pengembangan teknologi baterai di Indonesia.
