Abstract

Perkembangan baterai lithium ion sangat bervariatif terutama pada jenis elektrolitnya. Elektrolit cair pada baterai lithium-ion masih memiliki kekurangan yaitu ketidakstabilan pada temperatur tinggi sehingga rawan terbakar, oleh karena itu baterai lithium-ion berbasis elektrolit padatan (solid) dapat menjadi solusi dari kekurangan tersebut. Penelitian ini berfokus pada sintesis Li3BO3 yang akan digunakan sebagai bahan baku elektrolit solid jenis oksida berupa komposit LBSO (Li3BO3 dan Li2SO4) dan LSCO (Li2SO4-Li2CO3). Berdasarkan pengujian XRD variasi temperatur sintesis Li3BO3, pada sampel dengan temperatur 500oC dan 550oC, pola difraksi menunjukkan dominasi puncak difraksi Li3BO3 sedangkan pada variasi 600oC didapatkan puncak pengotor LiB(OH)4 sebagai puncak dominan dan tidak ditemukan fasa superionic pada semua variasi sintesis. Performa konduktivitas ionik optimum ada pada temperatur sintesis 600oC dengan nilai 3,27 x 10-4 S cm-1,kemudian sebesar 2,3 x 10-4 S cm-1 pada variasi 550oC dan 1,621 x 10-4 S cm-1pada variasi 500oC dimana ada keterkaitan antara peningkatan variasi temperatur sintesis Li3BO3 dengan konduktivitas ionik dari solid elektrolit, hal ini diakibatkan oleh pengaruh pengotor LiB(OH)4 yang memodifikasi sifat kristalin dari solid elektrolit LBSO-LSCO. Pada pengujian galvanostatic charge discharge tidak didapatkan reaksi charging yang sempurna dan tidak dapat melakukan performa discharge sehingga hal ini memerlukan identifikasi lebih lanjut.

The development of lithium ion batteries is very varied, especially in the type of electrolyte. Liquid electrolytes in lithium-ion batteries still have impefection, especially instability at high temperatures so they are prone to burning, therefore lithium-ion batteries based on solid electrolytes can be a solution to these shortcomings. This research focuses on the synthesis of Li3BO3 which will be used as raw material for solid oxide electrolyte in the form of LBSO-LSCO composite. The synthesis process is conducted by heating LiOH and H3BO3 (boric acid) powder and then proceeding in a furnace. XRD result shows of variations in temperature of Li3BO3 synthesis, in samples with temperatures of 500oC and 550oC, the diffraction pattern showed the dominance of the Li3BO3 diffraction peak, while at 600oC variation, the impurity peak of LiB(OH)4 was found as the dominant peak and no superionic phase was found in all synthesis variations. The optimum ionic conductivity performance is at a synthesis temperature of 600oC with a value of 3.27 x 10-4 S cm-1, , then 2.3 x 10-4 S cm-1 at a variation of 550oC and 1.621 x 10-4 S cm-1 at a variation of 500oC where there is a correlation between the increase in the temperature variation of the Li3BO3 synthesis and the ionic conductivity of the solid electrolyte, this is caused by the effect of LiB(OH)4 impurities that modify the crystalline properties of the solid electrolyte LBSO-LSCO. which is caused by the effect of LiB(OH)4 impurities that modify the crystalline properties of the solid electrolyte LBSO-LSCO. In the galvanostatic charge discharge test, no perfect charging reaction was found and it could not perform discharge performance, so this requires further identification.
