摘要
A solid-state thin film rechargeable battery has been prepared using a novel efficient technique of 'surface complexation method' by which a thin layer of Prussian blue (PB) can be overlaid on a solid polymer electrolyte of Nafion (Nf) as matrix. An electrochemical cell made of the composite PB-Nf film sandwiched with supporting electrodes was examined on i-v curves in solid state and for characteristics as a rechargeable battery. The resulting PB-Nf battery showed good durability in repetitive cycles of charging and discharging and gave the following results: open-circuit voltage of the unit cell per 160 mu m 0. 68 v, short-circuit current 0. 2-2 mA/cm**2 depending upon the water content of the Nf matrix, and an energy density of about 50 Wh/Kg.
