Abstract: Objectives Battery energy storage system is one of the effective means to ensure the reliability of photovoltaic (PV) power generation system and improve the utilization rate of PV
With the increasing proportion of distributed new energy in the grid, more and more battery storage systems are also connected to the grid to improve the negative impact of
Another significant problem is the interfacial compatibility of solid-state electrolytes with lithium metal. Most solid electrolytes have side reactions when they come into
Benefiting from the synergistic effects, we achieved a high energy density of 20.8 joules per cubic centimeter with an ultrahigh efficiency of 97.5% in the MLCCs. This approach should be universally applicable to

Introduction. Lithium-ion batteries have gained popularity as a method of energy storage due to their energy density of more than 250 Wh kg -1 and reasonable cost [1], [2].
Considerable efforts have been devoted to improving the energy storage performance of RFEs through designing the domain structure 3, 6, 19, defects types 4, 20, strain and interface state of the film 21, 22, 23, 24, 25, or selecting suitable material to construct composite dielectrics 10, 26.
Aqueous electrochemical energy storage devices are always limited in the inherited weaknesses of water, such as narrow operation temperature range and electrochemical stability window (ESW).
We then measured the thermal stability of the energy-storage performance in the range of −55° to 100°C (Fig. 4E and fig. S20). The MLCCs show good performance stability at an electric field of 500 and 700 kV cm −1 with degradation below ~10% for Ue and η over the entire measurement temperature range.
An overall estimation of energy-storage performance, calculated as UF = Ue / (1 − η) (34), reached a high value of 153.8 owing to the combined high Ue and ultrahigh η.
To evaluate the overall energy-storage performance of these ceramics, we measured the unipolar P - E loops of these ceramics at their characteristic breakdown strength (Fig. 3E and fig. S13) and calculated the discharged energy densities Ue and energy-storage efficiency η (Fig. 3F and fig. S14).
