  • Publication number: 20130252137
    Abstract: Disclosed is use of a porous membrane and a composite membrane thereof in a redox flow batteries, and in particular the use thereof in a vanadium redox flow battery. The membrane can effectively realize the separation of ions with different valence states, and an ion transfer without any ion exchange group. The pore size and structure of the porous membrane can be controlled by filling an inorganic substance or grafting an ion exchange group in the pore, in order to improve the barrier properties of the porous membrane for vanadium ions and to increase proton conductivity.

  • Publication number: 20120196188
    Abstract: A polymer ion exchange membrane for acidic electrolyte flow battery. The membrane is nitrogen heterocycles aromatic polymer, especially polybenzimidazole type polymer. A nitrogen heterocycles in the membrane interact with acid in the electrolyte to form donor-receptor proton transport network, so as to keep the proton transport performance of the membrane. The preparation condition for the membrane is mild, and the process is simplicity. The preparation method is suitable for mass production. The membrane is used in acidic electrolyte flow battery, especially in vanadium flow energy storage battery. The membrane has excellent mechanical stability and thermostability. In vanadium redox flow battery, the membrane has excellent proton conduct performance and excellent resistance to the permeation of vanadium ions.

  • Patent number: 8229375
    Abstract: A transmitting device, a transmit power control method and a control device thereof in a microwave system are provided. The transmitting device includes a transmit power control module, adapted to acquire a switching event of a modulation mode of the microwave system, and adjust a transmit power of a radio frequency transmitting module according to the switching event and a preset power control mode; and the radio frequency transmitting module, adapted to send a microwave signal to a communication peer end by adopting the transmit power adjusted by the transmit power control module. Through setting the power control module, the gain of an AM microwave system is enhanced, and the service impairment caused by the AM microwave system when actuating an ATPC function is avoided.
