Lithium cell
 A lithium cell having excellent discharging and recharging characteristics is proposed which is characteristic in the unique formulation of the polymeric solid electrolyte composition having a high ionic conductivity to fill the space between the anode and the cathode. The electrolyte composition comprises: (a) a block copolymer of styrene and 4-hydroxystyrene, of which the phenolic hydroxy groups in the 4-hydroxystyrene moiety are substituted by the grafting chains of poly(ethylene oxide) moiety having a specified chain length, (b) an ionic lithium salt and (c) a poly(ethylene oxide) in a specified weight proportion.
