摘要

In this work, the electrophoretic-deposition (EPD) method was used to fabricate pristine and composite ceramic-polymer membranes for application in planar and 3D microbattery configurations. The major focus was on the effect of polyethyleneimine additive on the morphology, composition, and electrochemical properties of the membrane. The ionic conductivity, cycleability, and charge/discharge behavior of planar LiFePO4/Li cells comprising composite porous YSZ-based membrane with impregnated LiPF6 EC:DEC electrolyte were found to be similar to the cells with commercial Celgard membrane. Conformal EPD coating of the electrode materials by a thin-film ceramic separator is advantageous for high-power operation and safety of batteries.
