Abstract

Telah berhasil dibuat membrane separator yang berpotensi diaplikasikan untuk baterai lihitum-ion, membrane separator digunakan untuk proses transfer ion dan mencegah terjadinya arus pendek. Dalam penelitian ini membrane separator PVA/SiO2 disintesis memggunakan metode electrospinning dengan variasi berat SiO2 (0, 0.6, 1.2, 2) wt%. SiO2 yang digunakan adalah hasil ekstraksi silika sekam padi. Pengaruh penambahan SiO2 pada PVA untuk meningkatkan karakteristik membrane diantaranya porositas, dan stabilitas pada suhu tinggi. Hasil membrane yang berhasil dibuat PVA, dan PVA/SiO2 membentuk serat nano dengan ukuran diameter serat semakin kecil ketika ditambahkan  SiO2 yaitu ~ 220 nm, ukuran diameter semakin kecil  meningkatkan porositas membrane dan meningkatkan kinerja membrane dengan stabilitas suhu 165 oC

Abstract

In order to coat the layer of the Cu for an anode-free lithium battery (AFLB) and examine AFLB performance, PVDF nanofiber with electrospinning is used. The fabrication time and molecular weight of the nanofiber can be modified. In comparison to conventional models, the AFLB is one of the new model options that provides great energy density at the same battery size. The disadvantages of this new model battery include its limited electrochemical performance and the fact that it is still in its initial stages of manufacturing. Low Coulombic efficiency and uncontrolled dendritic growth are challenges in the growth of AFLB. For the fabrication of nanofiber membranes were synthesized with different types of PVDF Mw 1.300.000 and 534.000, PVDF Nanofibers were made using electrospinning with time variations of 5 hours, 7 hours, and 9 hours, and their thermal, mechanical, and porosity properties were examined. The PVDF Mw 1.300.000 sample had the greatest porosity percentage value which is 47.031% during a 9-hour time. The PVDF Mw 534.000 sample had the highest tensile strength results, with a variation of 2.33 MPa during a 9-hour time. The PVDF Mw 1.300.000 sample had the highest percentage elongation results, 39.7%. The average nanofiber size varies with processing time, with the PVDF Mw 1.300.000 sample having the smallest size at 167.9 nm.
