What are the energy storage properties of BST glass–ceramics prepared by sol–gel method?
The maximum discharged energy density of 0.553 J/cm 3 and the highest energy efficiency of 94.5 % are obtained in samples with 2 mol% glass additive. From Fig. 4, the microstructures of BST glass–ceramics prepared by sol–gel method have strong impacts on their energy storage properties.
How to determine the optimal energy storage density?
Therefore, to obtain the optimal energy storage density, the glass content should be controlled in a relatively lower range. The charged energy density is equal to the integral of the area enclosed by charge curve and y -axis. The discharged energy density is equal to integral of the area enclosed by discharge curve and y -axis.
