PROBLEM TO BE SOLVED: To provide a polyelectrolyte for a lithium battery having a high ionic conductivity. SOLUTION: In this polyelectrolyte, two or more kinds of lithium salt are dissolved and at least one kind is an organic acid lithium salt shown in LiN (CnF2n+1SO2)(CmF2m+1SO2) (n=1 to 2, m=1 to 4), and this occupies 40-60 mol% among all the dissolved lithium salts. |
