Abstract

Baterai zinc ion atau Rechargeable zinc-ion batteries (RZIBs) adalah salah satu alternatif yang memiliki potensi besar untuk menggantikan performa lithium ion baterai lainnya. Hal ini dikarenakan RZIBs memiliki performa yang lebih baik seperti kapasitas energi yang tinggi dan kapasitas volumetrik yang besar. Pada penelitian ini dilakukan sintesis katoda MnO2/carbon cloth menggunakan prekursor KMnO4 dan NH4Br dengan metode hydrothermal oven dengan variasi waktu 5,10, dan 15 jam dengan temperature 180℃. Berdasarkan hasil uji karakterisasi didapatkan bahwa pengaruh waktu hydrothermal oven terhadap bentuk polimorfi yang terbentuk adalah α- MnO2. Morfologi yang terbentuk pada sampel 5,10, dan 15 jam yaitu berupa nanowires dan terlihat bahwa MnO2 tumbuh pada carbon cloth. Berdasarkan hasil pengujian performa elektrokimia didapatkan hasil bahwa baterai zinc ion yang memiliki performa paling baik diantara variasi lainnya yaitu pada variasi 15 jam. Sampel 15 jam memiliki nilai Rct sebesar 12,43 Ohm dengan coulombic efficiency sebesar 93% yang terjadi pada cycle ke 53 dan memiliki kapasitas sebesar 502.6 mAh/gr pada cycle ke 74 dan 489.9912037 mAh/gr pada cycle ke 80.

Zinc ion batteries or Rechargeable zinc-ion batteries(RZIBs) are an alternative that has great potential to replace the performance of other lithium ion batteries. This is because RZIBs have better performance such as high energy capacity and large volumetric capacity. In this research, the synthesis of MnO2/carbon cloth cathode was carried out using KMnO4 and NH4Br precursors using the hydrothermal oven method with variations in time of 5,10 and 15 hours with a temperature of 180℃. Based on the results of the characterization test, it was found that the effect of hydrothermal oven time on the polymorphic form formed was MnO2. The morphology formed in the 5,10, and 15 hours samples was in the form of nanowires and it was seen that MnO2 grew on the carbon cloth. Based on the results of electrochemical performance testing, it was found that the zinc ion battery has the best performance among other variations, namely the 15 hour variation. The 15-hour sample has an Rct value of 12.43 Ohm with a coulumbic efficiency of 93% which occurs in the 53rd cycle and has a capacity of 502.6 mAh/gr in the 74th cycle and 489.9912037 mAh/gr in the 80th cycle.
