Nonaqueous polymer electrolytes applications

In the case of ion conductive polymers, gel polymer electrolytes which consist of a polymer matrix, organic solvents and supporting electrolyte, were introduced as novel nonaqueous electrolyte systems in electrochemical applications, such as rechargeable batteries and electric double layer capacitors [3-5], Recently, considerable attention has been devoted to the application of gel poly-... 

When it comes to practical application, the actual conductance (the inverse of resistance R) instead of specific conductivity is the important variable. This is the reason why polymer electrolytes have drawn so much attention as a potential component of allmli-metal batteries aithough their specific conductivities are usually low ( 10 S cm ) compared with those at nonaqueous eiectrolytes (-10 S cm ). Calculate the conductance of 1.0 A/ LiSOjCFj in poiy(ethyiene oxide) and propylene carbonate, respectively. The former is fabricated into a fiim of 10 Tm thickness and the latter is soaked with porous separator of 1 mm thickness. (Xu)...

Among lyogels that contain nonaqueous solvent, elastic gels are especially noteworthy for battery applications. An elastic gel made of a polymer electrolyte can be prepared by applying heat or light onto the mixture of three components, namely, a network polymer from a polymer, a crosslinkable oligometer or a monomer, and electrolyte salt and solvent. It can exhibit the ionic conductivity comparable to solutions. The... 

In a recent patent application, Angell et al. described a series of alkylammonimn PILs, which are potentially useful as nonaqueous electrolytes in high-temperature polymer membrane fuel cells. The PILs investigated were stable to temperatures between 200 and 250 C, had conductivities comparable to aqueous solutions, and could be enhanced through the addition of a base with a pA a value intermediate between that of the acid and the base. ...
