Abstract

Lithium-ion batteries (LiB) play a major role in storage energy for a variety of applications ranging from portable electronic devices and hybrid/electric vehicles. Li-ion battery performance depends on cathode performance. Apart from the cathode, the dimensions of the battery also have an influence. In general, size The battery is directly related to its storage capacity. Reaction electrochemistry and ion exchange processes in Li-ion batteries are not just dependent on the properties of the electrode material and electrolyte, but also depends greatly on geometric structure and electrode size. By varying the dimensions of the folds batteries namely 6x5, 6x6, and 6x7, so the distance from the current collector is positive (aluminium) and negative (nickel) also vary. The farther the distance It is estimated that this will make battery performance less than optimal, and vice versa. Results Testing shows that the folded sample is smaller, namely 6x5 has an Rct value of 1.4675 Ω, while the 6x6 and 6x7 samples have a value Rct 1.656 Ω and 2.1107 Ω respectively. NMC541-6x5 has the capacity greatest discharge and efficiency, with a 50 cycle test average of 69.188 mAh.g-1 with an average efficiency of 99.436%. Samples with intermediate folds, namely The NMC541-6x6 has an average 50 cycle capacity and efficiency of 10,349 mAh.g-1 and 89.487% respectively. For samples with the smallest folds NMC541-6x7 is 0.178 mAh.g-1 and 48.816% respectively

Additional Information:	Baterai lithium-ion (LiB) memainkan peran utama dalam penyimpanan energi untuk berbagai aplikasi mulai dari perangkat elektronik portabel dan kendaraan hibrida/listrik. Kinerja baterai Li-ion bergantung pada kinerja katoda. Selain katoda, dimensi baterai juga memiliki pengaruh. Secara umum, ukuran baterai berhubungan langsung dengan kapasitas penyimpanannya. Reaksi elektrokimia dan proses pertukaran ion dalam baterai Li-ion tidak hanya bergantung pada sifat material elektroda dan elektrolit, tetapi juga sangat tergantung pada struktur geometris dan ukuran elektroda. Dengan memvariasikan dimensi lipatan baterai yakni 6x5, 6x6, dan 6x7, maka jarak dari pengumpul arus positif (aluminium) dan negatif (nikel) juga tervariasikan. Semakin jauh jaraknya diperkirakan akan membuat performa baterai kurang optimal, dan sebaliknya. Hasil dari pengujian memperlihatkan bahwa sampel yang dilipat lebih kecil yakni 6x5 memiliki nilai Rct sebesar 1,4675 Ω, sedangkan sampel 6x6 dan 6x7 memiliki nilai Rct 1,656 Ω dan 2,1107 Ω berturut-turut. NMC541-6x5 memiliki kapasitas discharge dan efisiensi terbesar, dengan pengujian 50 siklus rata rata sebesar 69,188 mAh.g-1 dengan rerata efisiensi 99,436 %. Sampel dengan lipatan menengah yakni NMC541-6x6 memiliki kapasitas dan efisiensi 50 siklus rata-rata sebesar 10,349 mAh.g-1 dan 89,487% berturut-turut. Untuk sampel dengan lipatan terkecil NMC541-6x7 sebesar 0,178 mAh.g-1 dan 48,816% berturut-turut.
