Abstract
Dalam penelitian ini dilakukan upaya untuk meningkatkan usia baterai lead-acid (cycle life) menggunakan dua jenis karbon yang memiliki luas permukaan dan jenis porositas yang berbeda. Carbon materials yang digunakan pada penelitian ini adalah karbon aktif (activated carbon) yaitu norit dan acetylene black. Jika penelitian yang dilakukan oleh D. Pavlov, P Nikolov, T.Rogachev dengan mencampur karbon ke dalam masa aktif, penelitian ini berusaha meningkatkan efektifitas penambahan karbon dengan cara melapiskannya pada permukaan elektroda negatif.
Penelitian ini diawali pelapisan Pb dengan karbon (norit dan acetylene black). Pelapisan dilakukan dengan cara bubuk karbon diberi tambahan CMC (Carboxymethyl cellulose) dengan perbandingan 5:1, kemudian diberikan beberapa tetes aquades hingga bertekstrur pasta. Tahap percobaan yang kedua adalah merangkai plat uji. Rangkaian plat uji terdiri dari plat positif dan negatif yang diikat dengan benang nylon, dan diberi kertas separator diantara plat. Tahap yang ketiga adalah pengujian baterai lead-acid yang telah dilapisi norit serta acetylene black. Pengujian charging dan discharging menggunakan alat 8-Channel Battery Analyzer dan Potentiostat.
Hasil yang ditunjukkan pada penelitian ini adalah pelapisan carbon materials di plat negatif memberikan pengaruh terhadap cycle life baterai lead-acid. Pelapisan plat negatif menggunakan acetylene black memiliki cycle life yang paling banyak yaitu 649 cycle. Setelah itu norit 11 cycle dan paling sedikit plat standar hanya 9 cycle. Hasil dari cyclic voltammetry (potentiostat) adalah kapasitas yang dimiliki plat, dimana kapasitas tertinggi dimiliki oleh norit, sedangkan kapasitas terendah dimiliki oleh acetylene black.
=============================================================================================================
This research tried to improve lead-acid battery cycle life using two kinds of carbon with different surface area and porosity type. Carbon materials used in this research is activated carbon which is norit and acetylene black. Though research that has been done by D. Pavlov, P. Nikolov., T. Rogachev mixing carbon into activated mass, this research tried to increase effectivity of carbon adding by coat it to the surface of negative electrode.
This research started by coating of Pb with carbon (norit and acetylene black). Coating was done by carbon powder that has been added by CMC (Carboxymethyl Cellulose) with ratio 5:1, then added by few drops of aquades until has paste texture. Second step of the experiment is assembled test plate. Test plate assembly consist of positive and negative plate connected by nylon string and given separator paper between plates. The third step is testing the lead-acid battery that has been coated by norit and acetylene black. Charging and discharging test using 8-Channel Battery Analyzer and Cyclic Voltammetry.
The results shown in this research are carbon materials coating in negative plate affected lead-acid battery cycle ife. Negative plate coating with acetylene black has more cycle life which are 649 cycles. Followed by norit with 11 cycles and the least of all standard plate with only 9 cycles. The result from cyclic voltammetry (potentiostat) is plate capacity, which highest capacity is norit and lowest capacity is acetylene black.
