“…Konduktivitas pada kitosan berasal dari pergerakan ion garam, dimana keadaan pergerakan ini selanjutnya dapat diperbaiki dengan adanya penambahan Plasticizer (Yahya & Arof, 2003). Rendahnya konduktivitas kitosan dikarenakan sedikitnya jumlah proton yang terdapat pada gugus-gugus pembentuk unsur kitosan (Smitha, dkk., 2003).…”

“…Mula-mula melarutkan kitosan sebanyak 40% berat dengan menggunakan asam asetat 1% sebanyak 50 mL, lalu diaduk dengan menggunakan magnetik stirer. Setelah itu melarutkan polivinil alkohol sebanyak 60% berat dengan menggunakan aquades sebanyak 30 mL (Yahya & Arof, 2003) Setelah keduanya larut, selajutnya menyaring dan mencampurkan kedua larutan tersebut dan mengaduknya kembali hingga campuran tersebut homogen. Setelah itu, menambahkan larutan ion litium 2% (w/w) ke dalam campuran tersebut selanjutnya menghomogenkanya kembali.…”

Keywords: battery, chitosan, polyvinyl, alcohol, kaolin, lithium, electrolyte membrane. PendahuluanKrisis 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

a b s t r a c tPhotovoltaic technologies represent one of the leading research areas of solar energy which is one of the most powerful renewable alternatives of fossil fuels. In a common photovoltaic application the batteries play a key role in storage of energy generated by solar panels. Although it will take time for dye sensitized solar cells (DSSCs) and batteries based on biopolymer electrolytes to take their places in the market, laboratory studies prove that they have a lot to offer. Most efficient DSSCs and batteries available in market are based on liquid electrolytes. The advantages of liquid electrolytes are having high conductivity and good electrode-electrolyte interface whereas, disadvantages like corrosion and evaporation limit their future sustainability. Biopolymer electrolytes are proposed as novel alternatives which may overcome the problems stated above. In this review, we focus on fabrication, working principle as well as up to date status of DSSCs and batteries using biopolymer electrolytes. The effects of structural and electrical properties of biopolymer based electrolytes on the solar energy conversion efficiencies of DSSCs and their compatibility with lithium or other salts in battery applications are summarized. Biopolymer electrolyte based DSSCs are categorized on the basis of types of additives and recent outcomes of author's laboratory studies on biopolymer electrolyte based DSSCs and batteries are also presented.

“…The mixture was stirred continuously with a magnetic stirrer at room temperature until the chitosan powder was completely dissolved in the weak acid solution. For the preparation of PGE films, a suspension was made by mixing appropriate amounts of EC, PC, LiClO 4 , and chitosan solution. The well-stirred suspension in a glass petri dish was heated at about 100 C for about 2 min.…”

“…Good amount of effort has been harnessed to produce chitosan-based polymer electrolytes. [3][4][5] Solid polymer electrolytes have ionic conductivity between 10 À8 and 10 À7 S cm À1 , which are too low to be of use in practical devices. Efforts 6 have, therefore, been expended to enhance the ionic conductivity of polymer electrolytes.…”

Studies on redox supercapacitors using electronically conducting polymers are of great importance for hybrid power sources and pulse power applications. In this study, electrochemical properties of a chitosan-based biodegradable polymer gel electrolyte (PGE) and a p/p polypyrrole supercapacitor fabricated using this electrolyte have been investigated. The variation of conductivity and dielectric properties of the electrolyte film with temperature has also been measured. The PGE film chosen for the study exhibited a specific conductivity of 5.5 Â 10 À3 S cm À1 . The electric modulus of the electrolyte film exhibits a long tail feature indicative of good capacitance. The fabricated supercapacitor showed a fairly good specific capacitance of 120 F g À1 and a time constant of 1 s.
