1. Introduction
The source of energy from “green materials” has gained signifi- cance due to the consequences of global warming and energy crisis. From this green viewpoint, many researchers took effort to develop new biopolymer electrolytes (BPEs). Biopolymer based electrolytes have overcome the main shortcoming of synthetic polymer electrolytes such as high cost and not being environmentally green. Hence, it is imperative to develop BPE in many electrochemical devices such as fuel cell, solar cell, battery, sensors and super capacitors (Ramesh, Liew, & Arof, 2011). In order to develop environment friendly polymer electrolytes, some of the essential and necessary requirements are membrane with good ionic conductivity, low cost, good dimensional and good mechanical stabilities (Samsudin, Khairul, & Isa, 2012). Natural polymers meet the above requirements so as to use as an elec-trolyte. Recently, researchers proposed many natural polymers such as cellulose and its derivative (Yue & Cowie, 2002; Yue, McEwen, & Cowie, 2003), starch (Ramesh et al., 2011), chitosan (Shukur, Yusof, Zawawi, Illias, & Kadir, 2013), and carboxylmetylcellulose (Samsudin, Lai, & Isa, 2014), which are suitable to be used as host polymer in the BPEs. Among the natural polymers, polysaccharide polymer cellulose acetate (CA) has got a number of good quality to process as membrane with good adhesion, an excellent transparency, nontoxic nature, low cost, biodegradable and biocompatible (Daniel Cerqueira, Artur Valente, Guimes Filho, & Hugh Burrows, 2009;Xiao et al., 2004). Due to this ability, CA has been studied intensely for various applications (Chou, Yu, Yang, & Jou, 2007; Edgar et al., 2001). Additionally, it contains anionic polysaccharide in its backbone, which has high affinity towards proton ions. The main limitation of CA has been attributed to its high crystalline nature, which gives the lowest ionic conductivity of order 10−7 S cm−1. To overcome the above limitation, natural polymer CA has been doped with ammonium salts like ammonium thiocyanate (NH4SCN) (Monisha et al., 2016; Woo, Majid, & Arof, 2012), ammonium nitrate (NH4NO3)(Kadir, Aspanut, Majid, & Arof, 2011), and ammonium iodide (NH4I) (Kumar, Tiwari, & Srivastava, 2012), which provide ions for conduction. Ammonium salts are chosen because it is considered as good proton donor to the polymer matrix (Chandra, Hashmi, & Prasad, 1990; Kumar & Sekhon, 2002). Daniel et al. found that in the polyethylene oxide (PEO)-ammonium hydrogen sulphate (NH4HSO4) and poly(acrylic acid) (PAA)-NH4HSO4 electrolytes anions were practically immobile and NH4 + cations were the dominant charge carriers (Daniel, Desbat, & Lassegues, 1998). Previous Researchers (Abidin, Ali, Hassan, & Yahya, 2013; Ramesh, Shanthi, & Morris, 2012; Ramesh, Shanthi, & Morris, 2013; Selvakumar & Krishna Bhat, 2008) have developed CA membrane using lithium salts. Recently, cellulose and its derivatives have been successfully employed in Li-ion batteries for the production of electrodes, separators or as reinforcing agents in gel polymer or solid polymer electrolytes. Cellulose based Li-ion batteries are well reviewed by Jabbour et al. (Jabbour, Bongiovanni, Chaussy, Gerbaldi, & Beneventi, 2013). Weng et al. investigated the use of fibrous cellulose membrane for developing the separators for high performance lithium ion batteries (Weng, Xu, Alcoutlabi, Mao, & Lozano, 2015). A cellulose based composite nonwoven has been explored as lithium ion battery separator by Zhang et al: The cell using the composite separators displayed better rate capability and enhanced capacity retention, which is compared to those of commercialized polypropylene separator (Zhang et al., 2013).
