What is a low recoverable energy storage density?

However, the low recoverable energy storage density (Wrec generally <4 J cm −3) greatly limits the application fields of ceramic capacitors and their development toward device miniaturization and intelligence.

Is ultrahigh recoverable energy storage density a bottleneck?

However, thus far, the huge challenge of realizing ultrahigh recoverable energy storage density (Wrec) accompanied by ultrahigh efficiency (η) still existed and has become a key bottleneck restricting the development of dielectric materials in cutting-edge energy storage applications.
