Discussion on the effect factors of the conductivity performance of PEO-based polymer electrolyte

摘要

Polymer electrolytes since the 1970s,the PV Wright,PEO polymers and inorganic salts can form complexes with high ionic conductivity.Thereafter,on a global scale,set off a craze of the theory with solid polymer electrolyte materials research and technology development,a lot of research work has been in the field to start and made great achievements in the preparation and study of different substrate materials composite polymer electrolytes,the most promising as lithium solid electrolyte materials.The polymer matrix itself large to have a high degree of crystallinity,this is very unfavorable to ion transport,therefore,to try to expand the ion transport required for the amorphous region and increase the migration of the polymer chain,and the electrolyte conductivity the rate is not only related with the polymer matrix,but also by the factors of the salt type and concentration of organic plasticizer and nano inorganic filler types and add methods.
