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.
