  • Patent number: 11177544
    Abstract: A battery device includes a case, a cell disposed within the case, and first and second conductive tabs each electrically connected to the cell and partly enclosed by the case. The first conductive tab has an elastic portion exposed from the case and compressible or stretchable when a force is applied thereto. By having the elastic portions that are elastically deformable, the effects of push or pull resulting from the swelling of the cell and case on the conductive tabs may be reduced. Consequently, damages or breakages of the conductive tabs can be avoided and the safety of battery device may be improved.

  • Patent number: 10964955
    Abstract: Methods and systems for providing battery backup power to a home or other building are disclosed. Methods and systems include a fluid container holding an electrolyte solution. The electrolyte solution is prevented from flowing through an array of galvanic cells having annular flow paths via a fluid flow control mechanism, such as a valve, which is energized by an external power source. When the external power source is removed, such as during a power outage, the fluid flow control mechanism is deenergized and electrolyte solution is allowed to flow through the galvanic cell array, generating electric current. Energy produced by the system then powers the home or other building until the external power source returns, which in turn closes the fluid flow control mechanism and ceases energy production by the system.
