Abstract: The nanoparticles of Mn1.5 [Cr(CN)6 ]∙ m H2 O@Ni1.5 [Cr(CN)6 ]∙ n H2 O core-shell prussian blue analogues (PBA) embedded with carbon additives (PBA-C) were synthesized and characterized as electrode material for solid state battery application. The impedance spectroscopy and cyclic voltametry were used to study the electrochemical properties by adding functionalized carbon in 1:1 proportion to improve the electrical performance. The value of room temperature electrical conductivity of core-shell PBA and core-shell nanoparticles mixed with vulcan carbon (PBA-C) are found to be 1.574 × 10 −3 and 1.92 × 10 −3 Scm −1, respectively. Using Li7 La3 Zr2 O12 (LZZO) electrolyte, single cell was fabricated with PBA-C material, and studied its charging-discharging cycles, which exhibits higher current density with stable performance for 400 cycles for time slots of 400 min. The study reveals that the PBA core-shell nanoparticles mixed with carbon (PBA-C) may be a potential candidate as an electrode material in the form of a single cell using LZZO electrolyte. Highlights: The electrical conductivity of PBA and PBA-C are 1.574 × 10 −3 and 1.92 × 10 −3 Scm −1, respectively. Li7 La3 Zr2 O12 (LZZO) electrolyte is used to fabricate single cell with PBA-C material. Stable charging-discharging cycles for 400 cycles for time slots of 400 min. PBA-C observed to be a significant and active battery materials for next generation.
