  • Patent number: 11056743
    Abstract: A package structure and its related electricity supply system are disclosed. Two substrates of the package structure are directly or indirectly served as current collectors of the electricity supply system. The sealing frame of the package structure is made of several silicone layers having high moisture-resistance and/or high gas-resistance. Hence, the package structure mentioned may not only provide a novel electrical conduction module to lower the intrinsic impedance of the electricity supply system itself but prevent the moisture and the gas outward from the electricity supply unit inside the package structure as well. Consequently, the electrical performance and safety of the electricity supply system are both improved.

  • Patent number: 10886553
    Abstract: Systems and methods providing modular and scalable flow batteries are disclosed. The modular design can utilize the ability of flow batteries to separate power, provided by a battery stack, from energy, provided by a stored electrolyte. Power of the system can be determined by a number of battery cell stacks, while stored energy capacity of the system can be determined by how much electrolyte is available for use by the battery cell stacks. Catholyte and anolyte solutions can be stored in pipes having an adjustable length. Electrolyte storage capacity can be increased by increasing the length of the pipes by an amount sufficient to provide a desired increase in electrolyte storage. Alternatively, electrolyte storage capacity can be decreased by decreasing the length of the pipes.
