Pendahuluan Krisis energi merupakan salah satu tantangan paling berat yang dihadapi manusia dewasa ini karena semakin menipisnya cadangan sumber energi fosil, sementara kebutuhan akan energi terus mengalami peningkatan seiring dengan perkembangan aktivitas manusia. Kenyataan ini telah mendorong penelitian untuk pengembangan beragam sumber energi alternatif di berbagai negara di dunia, salah satunya adalah baterai. Prinsip kerja baterai (accu) sangat mirip sekali dengan sel bahan bakar dimana keduanya sama-sama mempunyai komponen utama elektroda dan elektrolit. Baterai merupakan sumber energi utama yang paling praktis dan murah digunakan oleh masyarakat dunia saat ini. Perkembangan baru teknologi baterai telah mengarah pula pada baterai dalam bentuk yang tipis serupa kertas (Li-ion nanocomposite paper) (Hu, dkk., 2010). Elektrolit polimer dapat menggantikan elektrolit cair. Jenis elektrolit cair memiliki kelemahan diantaranya rentan terhadap kebocoran dan mudah terbakar jika terkena percikan api serta bersifat beracun, sedangkan untuk elektrolit dengan bentuk padatan (solid) lebih aman, mudah dipakai, bebas dari kebocoran dan dapat dibuat dengan dimensi lebih kecil seperti lapisan tipis (Gray & Armand, 1999). Elektrolit polimer padat Solid Polymer Electrolyte (SPE) tersusun atas penggabungan bahan anorganik seperti garam lithium dalam matriks polimer. Bahan-bahan ini menunjukkan Today, batteryis themost practical and in expensive energy storage device in modern community. A varietyof new materials technologies has been developedin the manufacture of the battery, especially the development of the solid electrolyte (solid). Polymer Electrolytes can be found in the polymer batteries form such as lithium ion polymer battery. A natural polymer such as chitosan is potentially as polymer electrolyte membrane for battery applications. Te chitosan has amino and hydroxyl groups that allows for modifcation. Te modifcation of chitosan membrane is expected to produce the better membranes characters. Te aim of this research is to study the efect of addition of inorganic fller kaolin on the conductivity of the polymer electrolyte that made of chitosan-polyvinyl alcohol then was added to the lithium salt. Te ionic conductivity of the polymer electrolyte chitosan-polyvinyl alcohol-lithium-kaolin was measured by usingan impedance spectroscopy. Te measurement results showed that the polymer electrolyte chitosan-polyvinyl alcohol-lithium with the addition of 4% kaolin provide the highest ionic conductivity is large 6.551x10 -5 S/cm. In comparison, characteristics of batteries that made from polymer electrolyte chitosan-polyvinyl alcohol-lithium with the addition of kaolin have a voltage of 2.4 volts which have similarities to the commercial batteries. Tis result indicates that the kaolin can be used as a fller to increase the ionic conductivity of the polymer electrolyte chitosan-polyvinyl alcohol- lithium, and then it can be developed as a battery.
