Abstract:

BaTiO3-based materials show great promise for energy storage capacitors, but their low breakdown strength and high remnant polarization currently result in relatively low energy density. Here, we report a novel (1-x)BaTiO3-xBi(Li0.5Ta0.5)O-3 (0.06 <= x <= 0.12, BT-xBLT) lead-free ceramic with electric field (E) similar to 280 kV cm(-1), discharge energy density (W-e) similar to 2.2 J cm(-3), charge-discharge efficiency (eta) > 89% that is thermally stable up to 160 degrees C and with a fast discharge time (< 0.5 mu s). Multilayers of compositions with x = 0.1 also exhibited high W-e = 4.05 J cm(-3) and eta = 95.5%, demonstrating their potential for energy storage.
