    摘要: An example of a circuit for generating high-voltage switching at an output terminal of the circuit includes a pair of n-type metal oxide semiconductor (NMOS) transistors responsive to input signals to generate a first voltage signal in a preset mode. The circuit also includes a predefined number of n-type cascode stages coupled between the output terminal and the pair of NMOS transistors to enable propagation of the first voltage signal to the output terminal. Further, the circuit includes a predefined number of p-type cascode stages coupled to the output terminal to enable propagation of the first voltage signal to an input voltage supply to the circuit. Furthermore, the circuit includes a first pair of cross-coupled p-type metal oxide semiconductor (PMOS) transistors coupled to the input voltage supply. The circuit includes a pair of PMOS transistors, coupled between the first pair of cross-coupled PMOS transistors and the p-type cascode stage.

    摘要: Methods are provided for forming films of orthorhombic V2O5. Additionally provided are the orthorhombic V2O5 films themselves, as well as batteries incorporating the films as cathode materials. The methods use electrodeposition from a precursor solution to form a V2O5 sol gel on a substrate. The V2O5 gel can be annealed to provide an orthorhombic V2O5 film on the substrate. The V2O5 film can be freestanding such that it can be removed from the substrate and integrated without binders or conductive filler into a battery as a cathode element. Due to the improved intercalation properties of the orthorhombic V2O5 films, batteries formed using the V2O5 films have extraordinarily high energy density, power density, and capacity.
