Why are lead-free ceramics important for energy storage applications?

Lead-free ceramics play a vital role in the context of sustainable development for energy storage applications due to their high power density, excellent high temperature resistance and nontoxicity. Nevertheless, the low energy density and small energy conversion efficiency of lead-free ceramics caused by th

What is the energy storage density of lead-free ceramics?

However, the recoverable energy storage density (Wrec) and energy storage efficiency (η) of most lead-free ceramics are less than 4 J cm −3 and 80%, respectively, due to their low electric breakdown strength (Eb), large remnant polarization (Pr) and/or small maximum polarization (Pmax).
