“…Pure i-carrageenan has a characteristic peak centered at 22.1°indicating its semi crystalline nature. The sharp peaks at 31.9°and 45.7°are due to impurities [8,9]. It is obvious from the XRD patterns that the characteristic peak becomes less prominent in the complexed membranes with the increasing concentration of LiCF 3 SO 3 .…”

In the present work, iota-carrageenan (i-carrageenan) biopolymer derived from edible seaweed has been chosen as the host polymer material for battery electrolyte. Ionic salt of lithium trifluoromethanesulfonate (LiCF 3 SO 3 ) commonly known as lithium triflate has been added with the host polymer as a source of charge carriers. The polymer membranes of 1.0 g i-carrageenan with LiCF 3 SO 3 of various compositions (0.1 wt% to 0.5 wt%) have been prepared by solution casting technique. X-ray diffraction (XRD) results indicate the enhancement in amorphous nature of polymer membranes due to the addition of LiCF 3 SO 3 . Complex formation between the salt and polymer has been studied by Fourier Transform Infrared (FTIR) spectroscopy. The high ionic conductivity of 1.27×10 −3 S cm −1 at room temperature is achieved with the combination of 1.0 g i-carrageenan : 0.4 wt% LiCF 3 SO 3 by AC impedance analysis. Total ion transference number estimated for the highest conducting sample is 0.95 by Wagner's DC polarization method and electrochemical stability of the same is 3.52 V by Linear Sweep Voltammetry (LSV) measurement. Lithium ion conducting battery has been fabricated using the highest conducting polymer membrane. Its open circuit voltage is measured as 1.70 V and its performance is studied.

“…The use of chitosan combined with a PEG plasticizer leads to an SPE with an excellent room temperature ionic conductivity, due to increasing polymer chain flexibility attributed to the plasticizer addition, making this a promising option for application in batteries [276]. Iota-Carrageenan [277], pectin, and guar gum [278] are other promising polymers that can achieve high room temperature ionic conductivity (in the order of 10 −4 S•cm −1 ). The use of water as solvent in a super hydrophilic PAA matrix doped with silica nanoparticles presents outstanding ionic conductivities above 10 −2 S•cm −1 , being a promising candidate for aqueous rechargeable lithium-ion batteries [279].…”

Environmental issues related to energy consumption are mainly associated with the strong dependence on fossil fuels. To solve these issues, renewable energy sources systems have been developed as well as advanced energy storage systems. Batteries are the main storage system related to mobility, and they are applied in devices such as laptops, cell phones, and electric vehicles. Lithium-ion batteries (LIBs) are the most used battery system based on their high specific capacity, long cycle life, and no memory effects. This rapidly evolving field urges for a systematic comparative compilation of the most recent developments on battery technology in order to keep up with the growing number of materials, strategies, and battery performance data, allowing the design of future developments in the field. Thus, this review focuses on the different materials recently developed for the different battery components—anode, cathode, and separator/electrolyte—in order to further improve LIB systems. Moreover, solid polymer electrolytes (SPE) for LIBs are also highlighted. Together with the study of new advanced materials, materials modification by doping or synthesis, the combination of different materials, fillers addition, size manipulation, or the use of high ionic conductor materials are also presented as effective methods to enhance the electrochemical properties of LIBs. Finally, it is also shown that the development of advanced materials is not only focused on improving efficiency but also on the application of more environmentally friendly materials.
