对多种新型Li离子导电的polymer_in_salt固体电解质的导电性及其影响因素进行了研究.这种固体电解质是将很少量的单离子聚合物电解质———聚丙烯酸锂熔于低温共熔锂盐中得到的,室温电导率为10-5S/cm(29℃),较由聚氧化乙烯(PEO)制造的polymer_in_salt固体电解质,电导率有明显地提高.
Various novel predominantly lithium_ion_conducting solid state electrolytes were described, which had high conductivity at room temperature. It comprised low_melting_point eutectic lithium salts in which a small amount of an single ion polyeletrolyte poly(lithium acrylate) was dissolved to rubberize them. The effects of the eutectic and polymer features upon the ionic conductivity were discussed.
