BaTiO3–Bi(Li0.5Ta0.5)O3, Lead-Free Ceramics, and Multilayers with High Energy Storage Density and Efficiency

“…280 kV cm -1 but then reduces to 225 kV cm -1 with increase in BLT concentration and is significantly greater than most BT-based bulk ceramics. [28][29][30][31][32][33][34][35][36] The We of the BT-BLT samples was measured by using P-E hysteresis loops in Fig. S3a.…”

“…25 Pr. 34,35 In this contribution, a further relaxor ferroelectrics BT-xBLT (0.06 ≤ x ≤ 0.12) was designed with enhanced E ~ 280 kV cm -1 , We ~ 2 J cm -3 and ~ 88%. Multilayers of the ceramic compositions also exhibited promising properties with E ~ 466 kV cm -1 , We ~ 4.05 J cm -3 and ~ 95.5%.…”

“…High Eb ~ 466 kV cm -1 is observed, favourable for high We which along with the slim P-E loops is expected to give rise to high energy storage density. The studies have been shown that high is demanded of multilayers in energy storage applications as waste heat causes potential dissipation problems in the chargedischarge progress [35][36][37][38][39].

Enhanced energy storage properties of barium strontium titanate ceramics prepared by sol-gel method and spark plasma sintering

“…This is detrimental to the performance and reliability of capacitors. To the best of our knowledge, there are few reports about the efficiency greater than 90% obtained in nonlinear dielectrics [34][35][36][37][38]. This is mainly because the efficiency would decrease rapidly with the increasing applied electric field due to the conduction loss [39,40].…”
