Lead-based and lead-free ferroelectric ceramic capacitors for ...

A few Pb-free FE ceramic systems have been investigated as energy storage capacitors, which mainly included BaTiO 3 (BTO), BiFeO 3 (BFO), and (Bi,Na)TiO 3 (BNT)-based bulk ceramics and films. As typical FE materials, these ceramics display broad P – E loops with high P r and E c but low P s – P r, resulting in low U rec and η .
