Abstract
Material anoda LIB bekas berhasil digunakan kembali sebagai material anoda baterai ion litihum baru melalui pemisahan secara mekanis, pencucian dengan DMC dan NMP, serta pembakaran pada suhu 600oC. Material anoda pada LIB bekas dan LIB baru menunjukkan struktur grafit (JCPDS No. 96-901-1578). Hasil karakterisasi FTIR menunjukkan bahwa perlakuan yang diterapkan berhasil mengurangi pengotor. Pembuatan slurry dilakukan dengan perbandingan material aktif : binder : adiktif = 85 : 10 : 5, dengan pelarut NMP. Grafit ditambahkan sebanyak 5% dari berat sampel ke dalam material aktif anoda untuk menambah komposisi grafit. Hasil uji performa baterai menunjukkan bahwa penambahan grafit dapat menaikkan arus baterai (2,771 mA) tetapi tidak menaikkan potensial dan kapasitas baterai. Hasil voltametri siklik menunjukkan potensial rata-rata dari anoda LIB bekas (0,118 V) lebih tinggi dibandingkan anoda LIB baru (0,100 V). Hasil charge-discharge menunjukkan anoda LIB bekas hasil perlakuan tanpa penambahan grafit memiliki efisiensi tertinggi (98%) dan kapasitas tertinggi (charge 148,374 mAh/g dan discharge 151,489 mAh/g). Nilai kapasitas yang diperoleh lebih tinggi daripada material anoda tanpa dilakukan perlakuan.

Used lithium ion battery (LIB) anode material has been successfully reused as a new lithium ion battery anode material by mechanical separation, DMC and NMP washing, and calcination at 600oC. XRD analysis showed that the anode material from used and new LIB shows a graphite structure (JCPDS No. 96-901- 1578). The FTIR spectra indicates that treatment has succeeded in reducing impurity. LIB anode slurry was made with a composition of active material: binder: additive = 85: 10: 5, mixed in NMP solvents. Graphite of 5% was added to the anode active material to increase the graphite content in anode materials. The battery performance show that the addition of graphite can increase the battery current (2.771 mA) but does not increase the battery potential and capacity. The cyclic voltammetry analysis shows that the average potential of used LIB anodes (0.118 V) was higher than the new LIB anode (0.100 V). The charge-discharge result shows that the used LIB anode after treated without graphite addition, has the highest efficiency (98%) and capacity (charge 148,374 mAh/g and discharge 151,489 mAh/g). The obtained capacity values were higher than the anode material without treatment.
