“…To overcome the defects of polyolefin microporous membranes, poly(acrylonitrile) (PAN)-based [8][9][10][11][12][13][14][15] and poly(vinylidene fluoride) (PVDF)-based [1,6,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] microporous membranes are widely studied as alternative separator for lithium-ion batteries because of their excellent miscibility with the liquid electrolyte. And then, the batteries can be packed using laminated flexible foils instead of metal cans, which enhance the energy density and safety of lithium-ion batteries.…”

In this work, a special structural poly(acrylonitrile) (PAN)-based microporous membrane for lithium-ion batteries is prepared from PAN emulsion by simple casting and extracting techniques. It is found that the microporous membrane is fabricated by PAN particles with uniform size (about 580 nm), and a lot of micropores exist among the particles. The Gurley number of the microporous membrane obviously depends on the amount of additive but the porosity does not. The PAN-based microporous membrane is activated by non-aqueous liquid electrolyte to form microporous gel electrolyte (MGE), and its ionic conductivity increases with the decrease of the Gurley number. The resulting MGE shows typical thermal shut-down action because of the swellingincorporating behaviors of PAN-based particles by the help of the solvent of liquid electrolyte at high temperature. In addition, the electrochemical stability window of the MGE can extend to 5.5 V vs. Li + /Li. The test cell using MGE as separator shows high initial discharge capacity (143 mAh g -1 based on LiCoO 2 ) and high capacity retention ratio (around 94.8% at the 50th cycle). Generally, the special structural microporous membrane is promisingly used to prepare highsafety lithium-ion batteries.

:Increasing demand of energy, the depletion of fossil fuel reserves, energy security and the climate change have forced us to look upon alternate energy resources. For today's electric vehicles that run on lithium-ion batteries, one of the biggest downsides is the limited range between recharging. Over the past several years, researchers have been working on lithium-air battery. These batteries could significantly increase the range of electric vehicles due to their high energy density, which could theoretically be equal to the energy density of gasoline. Li-air batteries are potentially viable ultrahigh energy density chemical power sources, which could potentially offer specific energies up to 3000 Whkg −1 being rechargeable. This paper provides a review on Lithium air battery as alternate energy resource for the future.
