During synthesis of Polymer-salt composite, ether Oxygen (O): M+ (metal ion of salt) ratio is varied eg. 8:1, 25: 1 etc. that means unit M+ coordinated to ether oxygen.
But could anyone suggest me the method of ab initio calculation? Eg. For PEO =(M.W =100000) + Li+ salt in 5:1 ratio..

Go by the ratio of ethylene oxide and Metal. For ethylene oxide 44g (E.O.) and Metal salt molecular weight (Li-perchlorate 106g). You have to decide the ratio depending on how many Oxigen atoms are involved in salt making. Safely 4 O vs. one Li+. Practically, you can use much lowe Li+ to avoid ion pairing causing salting out.. Basis for calculation is explained above. But practically, it depends on researcher.
