50 μm-thick ( Pb 0.97 La 0.02)( Zr 0.92 Sn 0.05 Ti 0.03) O 3 antiferroelectric (AFE) thick films with different amount of 0.8 PbO –0.2 B 2 O 3 glass additions were fabricated by the screen-printing method on alumina substrate, which was pre-coated with Pt as electrode. The effects of glass additions on dielectric properties and energy storage performance were investigated in details. Due to the enhancement of breakdown strength (BDS) of the specimens by the addition of glass, the energy storage performances of the thick films could be greatly improved. As a result, with 3% glass addition, the BDS of the specimens were as high as 475 kV/cm, the maximum polarization of 34.8 μC/cm2 and the maximum recoverable energy storage density of 7.4 J/cm3 were obtained. The results indicated the ( Pb 0.97 La 0.02)( Zr 0.92 Sn 0.05 Ti 0.03) O 3 (PLZST) thick films have a promising potential application in capacitors for pulsed power systems.

Sodium Sulfur

Lithium metal batteries have achieved large-scale application, but still have limitations such as poor safety performance and high cost, and limited lithium resources limit the production of lithium batteries. The construction of these devices is also hampered by limited lithium supplies. Therefore, it is particularly important to find alternative metals for lithium replacement. Sodium has the properties of rich in content, low cost and ability to provide high voltage, which makes it an ideal substitute for lithium. Sulfur-based materials have attributes of high energy density, high theoretical specific capacity and are easily oxidized. They may be used as cathodes matched with sodium anodes to form a sodium-sulfur battery. Traditional sodium-sulfur batteries are used at a temperature of about 300 °C. In order to solve problems associated with flammability, explosiveness and energy loss caused by high-temperature use conditions, most research is now focused on the development of room temperature sodium-sulfur batteries. Regardless of safety performance or energy storage performance, room temperature sodium-sulfur batteries have great potential as next-generation secondary batteries. This article summarizes the working principle and existing problems for room temperature sodium-sulfur battery, and summarizes the methods necessary to solve key scientific problems to improve the comprehensive energy storage performance of sodium-sulfur battery from four aspects: cathode, anode, electrolyte and separator.
