“…116 The structural design of copolymerizing PAN with other monomer and/or other functional groups has been intensively investigated by many scientists. Taking advantage of poly(vinyl acetate) to solvate Li + and the good mechanical strength of PAN, a copolymer poly(acrylonitrile-vinyl acetate) (P(AN-VAc)) has been successfully synthesized by Li et al 117 The resulting copolymer was coated on PE nonwoven fabric and activated by 1 M LiPF 6 in DMC/DEC/EC (1:1:1, v/v/v). The corresponding GPE revealed an ionic conductivity up to 3.8 × 10 −3 S cm −1 at room temperature, Li + transference number as high as 0.52, and stable electrochemical windows from 5.0 to 5.6 V vs Li/Li + .…”

Electrolytes have played critical roles in electrochemical energy storage. In Li-ion battery, liquid electrolytes have shown their excellent performances over decades, such as high ionic conductivity (∼10–3 S cm–1) and good contacts with electrodes. However, the use of liquid electrolytes often brought risks associated with leakage and combustion of organic electrolytes. Hence, polymer electrolytes become potential candidates to replace liquid electrolyte systems. Although solid polymer electrolytes (SPEs) offer better safety and good mechanical properties to take over liquid electrolytes, most of them only deliver low ionic conductivities (∼10–8 S cm–1) and poor contact with electrodes, resulting in poor cycle performance and low electrical capacity of the batteries. In addition, gel polymer electrolytes (GPEs) have received increasing research attention due to their relevant characteristics, which extend from liquid electrolytes and solid polymer electrolytes. In this review, state-of-the-art samples of gel polymer electrolytes are elucidated with respect to their structural design and electrochemical properties to determine their application potential in Li-ion batteries (LIBs). First, we present the general requirements of GPEs for LIBs applications, followed by important electrochemical properties of GPEs for LIBs including ionic conductivity, transference number, and ionic transport mechanisms. Furthermore, recent progress of common polymers, namely, polyether, polyvinyl, polynitrile, polycarbonate, and polyacrylate, as polymer host of GPEs has been carefully explained. Finally, the alternative polymers were also discussed to provide new approaches for further developments of GPEs to fulfill the demanded properties for practical applications.

In this article, we report a novel gel polymer electrolyte (GPE) for lithium ion battery, which is prepared by using poly(methyl methacrylate-acrylonitrile-ethyl acrylate) (P(MMA-AN-EA)) as polymer matrix and doping nano-SiO 2 and nano-Al 2 O 3 simultaneously.The influences of the ratio of two nanoparticles on the pore structure, electrolyte uptake and thermal stability of the resulting membrane and the ionic conductivity and electrochemical stability of the corresponding GPE are understood by scanning electron microscopy, mechanical strength, thermogravimetry, electrochemical impedance spectroscopy, linear sweep voltammetry and cyclic voltammetry. Particularly, the performance of the developed GPE for its application in lithium ion battery is evaluated in Li/LiNi 0.5 Mn 1.5 O 4 half cell by charge/discharge test. It is found that there exists a synergistic effect between nano-SiO 2 and 2 nano-Al 2 O 3 . The performances of the resulting membrane and the corresponding GPE are effectively improved by using nano-SiO 2 and nano-Al 2 O 3 simultaneously than individually.Co-doping 5 wt.% nano-SiO 2 and 5 wt.% nano-Al 2 O 3 provides the membrane with a higher thermally decomposed temperature of 325 o C and a better electrolyte uptake of 198.1%, the corresponding GPE with an increased ionic conductivity of 2.2×10 -3 S.cm -1 at room temperature and an enhanced oxidative stability up to 5.5 V (vs. Li/Li + ), and the LiNi 0.5 Mn 1.5 O 4 cathode with an improved rate capability of 104.2 mAh.g -1 at 2 C and an improved capacity retention of 94.8% after 100 cycles. These improved performances result from the combining advantages of both nano-SiO 2 and nano-Al 2 O 3 , in which the former contributes to the improved ionic conductivity caused by stronger Lewis-acid property, while the latte to the better thermal and structural stability by its stiffness characterization.

The development of fl exible energy devices is dramatically increasing the requirement of gel polymer electrolyte (GPE) with mechanical robustness and excellent transport effi ciency of ion or solute. Some GPEs such as poly(vinylidene fl uoride) (PVDF) with glass fi bers, [ 12 ] nonwoven fabrics, [ 13 ] etc. have been reported for fl exible batteries. There is a remarkable ions migration effi ciency in these GPEs, which provides breakthrough electrochemical performances. Poly(vinyl alcohol) (PVA) hydrogel is a widely used GPE substrate for supercapacitors. [ 5,14 ] However, current ionic conducting gels, which just consist of PVA hydrogels and inorganic salts, acid or alkali dissolved in water, are brittle and exhibit poor mechanical strength due to the damage of inorganic ions to the hydrogen bond between PVA polymer chains and water molecules. Furthermore, metal electrodes can be corroded by acid in the GPE during the charge-discharge process. Therefore, GPE with neutral salts is a promising new research fi eld for semi-solid-state supercapacitors. However, excess inorganic ions would infl uence the mechanical strength of the gels because of the coagulation with PVA chains in water. Consequently, the ionic conductivities of GPE are generally low (0.1-10 mS cm −1 ) due to the limitation of salts content (generally lower than 20 wt%) in gels. Up to date, the problem that inorganic salts cannot be added into gel polymer substrate in large quantities has not been settled.Common neutral GPE contains much water, and the potential window of the aqueous GPE is limited to the ideal maximum value of 1.23 V, usually used in the range of 0-0.80 V which also places restrictions on the application of such supercapacitors. And aqueous GPE cannot maintain a stable appearance with the gradual loss of water which also infl uences the electrochemical behavior of supercapacitors. [ 15 ] Ionic liquids (ILs) recently attain more attention in the applications of energy storage, such as semi-solid-state supercapacitors, because of their wide operation potential, high thermal and electrochemical stability as conducting medium relative to inorganic salts. However, their low conductivities restrict the electrochemical performance in semi-solid-state supercapacitors. [ 1,16,17 ] The ionic conductivity can be improved further with a wide operation electrochemical window after the addition of neutral inorganic salts in the GPE, which opens up new access to high-performance EDLCs, but related researches are lacked.
