Abstract

Currently, the use of new, renewable and environmentally friendly energy is increasing. There has been a lot of research and technological innovation carried out to produce energy conversion equipment using new, renewable energy. Batteries are used to store this energy because the energy converted is electrical energy. Therefore, it is also important to understand the battery assembly and characterization process so that the battery manufacturing process becomes more effective and efficient. Currently, much research has been carried out on battery design on the influence of battery performance. Previous research included the influence of length, width and layer thickness of the anode and cathode sheets. The current research focuses on the length of the anode and cathode sheets. The research began by synthesizing the cathode material LiNi0.5Mn0.4Co0.1O2 (NMC541). After obtaining the NMC 541 active cathode material, the battery assembly process is carried out. The assembly process begins with a mixing process. After that, it goes through a coating process until finally the battery is assembled in the glove box. The next step is to carry out electrochemical testing of the battery including charge�discharge tests, cyclic voltammetry (CV), impedance capacitance resistance (LCR) meter, and electrochemical impedance spectroscopy (EIS). The optimal electrode ratio occurs at a ratio of 37.5:37.5. Meanwhile, the ratios 35:40 and 40:35 produce lower electrochemical performance than the ratio 37.5:37.5. A ratio of 35:40 produces a capacity of 42.164 mAh.g-1 , electron transfer resistance of 0.07Ω, anodic voltage of 4.1971 V, cathodic voltage of 3.4447 V, anodic current of 0.091364 A, and cathodic current of 0.074521 A. Ratio 40:35 produces a capacity of 152.781 mAh.g-1 , anodic voltage 4.1989 V, cathodic voltage 3.7374 V, anodic current 0.03969 A, and cathodic current 0.005369 A.

Additional Information:	Pada saat ini, penggunaan energi baru terbarukan dan ramah lingkungan semakin meningkat. Sudah banyak penelitian dan inovasi teknologi yang dilakukan untuk menghasilkan peralatan konversi energi menggunakan energi baru terbarukan. Dalam menyimpan energi tersebut digunakan baterai karena energi yang dikonversikan merupakan energi listrik. Oleh karena itu, penting juga untuk dipahami mengenai proses perakitan dan karakterisasi baterai agar proses manufaktur baterai menjadi lebih efektif dan efisien. Pada saat ini, penelitian terhadap desain baterai terhadap pengaruh performa baterai sudah banyak dilakukan. Penelitian sebelumnya meliputi pengaruh panjang, lebar, dan tebal lapisan dari lembaran anoda dan katoda. Pada penelitian saat ini berfokus kepada panjang lembaran anoda dan katoda. Penelitian diawali dengan melakukan sintesis material katoda LiNi0,5Mn0,4Co0,1O2 (NMC541). Setelah mendapatkan material aktif katoda NMC 541 dilakukan proses perakitan baterai. Proses perakitan diawali dengan proses mixing. Setalah itu, melalui proses coating hingga akhirnya baterai dirakit didalam glove box. Langkah berikutnya adalah melakukan pengujian elektrokimia baterai meliputi uji charge-discharge, cyclic voltammetry (CV), impedance capacitance resistance (LCR) meter, dan electrochemical impedance spectroscopy (EIS). Rasio elektroda optimal terjadi pada rasio 37,5:37,5. Sementara itu, rasio 35:40 dan 40:35 menghasilkan performa elektrokimia lebih rendah dibandingkan rasio 37,5:37,5. Rasio 35:40 menghasilkan kapasitas 42,164 mAh.g�1 , hambatan transfer elektron 0,07Ω, tegangan anodik 4,1971 V, tegangan katodik 3,4447 V, arus anodik 0,091364 A, dan arus katodik 0,074521 A. Rasio 40:35 menghasilkan kapasitas 152,781 mAh.g-1 , tegangan anodik 4,1989 V, tegangan katodik 3,7374 V, arus anodik 0,03969 A, dan arus katodik 0,005369 A.
