Electrolytes for solid-state batteries: glass transition temperature of polyether networks with and without alkali metal salts

Polymer Bulletin Aims and scope Submit manuscript

Summary

A detailed study was conducted on the dependence of the Tg of polyether networks as a function of type and size of polyether chain, nature of the crosslinking structure and alkali metal salt concentration. The nature of the branching moiety affects Tg but not the salt interactions with the network. A general law concerning the salt-containing network is obtained. It is characterized by the dominating interactions of the salt with polyethylene oxyde chains.
