Lithium-ion batteries are the most commonly used source of power for modern electronic devices. However, their safety became a topic of concern after reports of the devices catching fire due to battery failure. Making safer batteries is of utmost importance, and several researchers are trying to modify various aspects in the battery to make it safer without affecting the performance of the battery. Electrolytes are one of the most important parts of the battery since they are responsible for the conduction of ions between the electrodes. In this paper, we discuss the different non-flammable electrolytes that were developed recently for safer lithium-ion battery applications.

Electrochemical energy storage devices, such as lithium ion batteries (LIBs), supercapacitors and fuel cells, have been vigorously developed and widely researched in past decades. However, their safety issues have appealed immense attention. Gel electrolytes (GEs), with a special state in-between liquid and solid electrolytes, are considered as the most promising candidates in electrochemical energy storage because of their high safety and stability. This review summarized the recent progresses made in the application of GEs in the safety regulation of the electrochemical energy storage devices. Special attention was paid to the gel polymer electrolytes, the organic low molecule-mass GEs, as well as the fumed silica-based and siloxane-based GEs. Finally, the current challenges and future directions were proposed in terms of the development of GEs.

Functionalized fibers, especially polyacrylonitrile fibers (PANF), have attracted wide interest as an effective and economical material for environment and water protection. In this study, polyacrylonitrile fibers modified with hydroxylamine hydrochloride were used as an adsorbent to remove hexavalent chromium ions from aqueous solutions. The novelty of the present study compared to the literature is the functionalization of polyacrylonitrile fibers surface by optimizing cost and energy while achieving a yield fast removal rate and high adsorption capacity of hexavalent chromium from aqueous solutions. The amidoximated polyacrylonitrile fibers were characterized using Fourier Transform InfraRed spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The results confirmed the success of polyacrylonitrile fibers modification. The adsorption capacity was evaluated by investigating the effect of initial pH solution ranging from 2.0 to 7.0, the adsorbent dose varied from 0.05 to 0.25 g, the initial Cr (VI) concentration range was (5–70 mg g−1), the temperature varied from 5 to 60°C, and the contact time ranged from 0 to 180 min. We have used the Langmuir and Freundlich adsorption models to describe the equilibrium sorption data. The maximum adsorption capacity estimated using the Langmuir model reached 32. 57 mg g−1 under optimal conditions. The thermodynamic parameters (ΔG, ΔH, and ΔS) were also determined. In addition, the adsorbent showed a desorption rate of Cr (VI) up to 92% with 0.5 mol of NaOH, which can be reused for three adsorption–desorption cycles. The overall data showed the efficiency of amidoximated polyacrylonitrile fibers in removing Cr (VI) from aqueous solutions. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
