Abstract

Perkembangan baterai saat ini sangatlah pesat, namum demikian masih terdapat beberapa tantangan. Salah satu tantangan dalam penggunaan baterai saat ini adalah mudah terbakarnya komponen elektrolit. Solusi terkini yaitu menggunakan solid electrolyte.Penelitian ini berfokus pada sintesis LBSO yang akan digunakan sebagai bahan baku solid elektrolit yang berupa komposit gelas LBSO(Li3BO3 dan Li2SO4)- LSCO(Li2SO4-Li2CO3). Fokusan penelitian ini yaitu variasi rasio mol antara Li3BO3Li2SO4 pada proses sintesis LBSO untuk menganalisis struktur dan morfologi komposit LBSO-LSCO glass dan performa baterai all-oxide solid state dengan elektroda NMC (LiNi1/3Co1/3Mn1/3O2) dan LTO (Li4Ti5O12i). Hasil pengujian XRD solid elektrolit LBSO-LSCO masih memiliki pengotor berupa senyawa LiB(OH)4 atau LiBO2 .2H2O pada semua variasi. Performa konduktivitas ionik optimum ada pada variasi 8:2 LBSO yang disebabkan pengaruh pengotor LiB(OH)4 yang memodifikasi sifat kristalin dari solid elektrolit LBSO-LSCO. Pada pengujian galvanostatic charge discharge tidak didapatkan reaksi charging charging yang sempurna dan tidak dapat melakukan performa discharge sehingga hal ini memerlukan identifikasi lebih lanjut. ================================================================================================ Battery development is currently very fast, however, there are still some challenges. One of the challenges in using batteries today is the flammability of the electrolyte components. The latest solution is to use a solid electrolyte. This research focuses on the synthesis of LBSO which will be used as a solid electrolyte raw material in the form of glass composite LBSO(Li3BO3-Li2SO4)- LSCO(Li2SO4-Li2CO3). The focus of this research is the mole ratio variation between Li3BO3 and Li2SO4 in the LBSO synthesis process to analyze the structure and morphology of the LBSO- LSCO glass composite and the performance of all-oxide solid state batteries with NMC (LiNi1/3Co1/3Mn1/3O2) and LTO (Li4Ti5O12i) electrodes. The XRD test results for solid electrolyte LBSO-LSCO still have impurities in the form of LiB(OH)4 or LiBO2.2H2O compounds in all variations. The optimum ionic conductivity performance was at 8:2 LBSO variation due to the influence of LiB(OH)4 impurities which 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.
