Significant enhancement of energy storage properties of BaTiO3-based ceramics by hybrid-doping

Results showed that an enhancement of 76% over pure BaTiO3 in recoverable energy storage density (Wrec) has been achieved in hybrid-doped samples, accompanied by a high energy conversion efficiency (η) up to 86%. Hereinto, donor-dominant samples doped with 1% Mn and 1.25% Nb exhibited the highest Wrec and η with excellent thermal stability.
