✦ Synopsis
By the addition of extra salts such as LiBF 4 into a singleionic polymer solid electrolyte, poly[lithium bis{endomethyl-oligo(oxyethylene)oxy}-oligo(oxyethylene)oxyaluminate], the balance of transport number was controlled from t = 1 (t À = 0: single-ionic) to t % t À % 0.5. Since the state of t % t À could be realized over a wide concentration range of added LiBF 4 , this type of bi-ionic conductor could be useful in rechargeable batteries such as Li/electrolyte/poly(aniline) BF À 4 in which the concentration of LiBF 4 fluctuates during the charging/discharging processes by the ingress/egress of Li and BF À 4 . The [Li/electrolyte/poly(aniline) BF 4 À ] battery with transport number controlled electrolyte showed a distinct plateau voltage in discharge curves.
