  • ELECTRICAL CONNECTOR AND ELECTRICAL CONTACT CONFIGURED TO REDUCE RESONANCE
    Publication number: 20190074637
    Abstract: Electrical contact includes a base portion and a mating portion having a leading end of the electrical contact. The mating portion includes a contact finger coupled to the base portion and extends between the base portion and the leading end. The contact finger has an engagement surface that is shaped to define a primary contact zone. The electrical contact also includes a resonance-control protrusion shaped to define a stub-contact zone. The stub-contact zone is positioned at the base portion or between the base portion and the primary contact zone. The primary contact zone and the stub-contact zone are configured to engage another contact. The stub-contact zone is configured to impede electrical resonance along a stub portion of the other contact.

  • Electrode material and method of synthesizing
    Patent number: 10090516
    Abstract: The present disclosure provides a phosphate framework electrode material for sodium ion battery and a method for synthesizing such electrode material. A surfactant and precursors including a sodium precursor, a phosphate precursor, a transition metal precursor are dissolved in a solvent and stirred for sufficient mixing and reaction. The precursors are reacted to yield a precipitate of particles of NaxAbMy(PO4)zXn compound and with the surfactant attached to the particles. The solvent is then removed and the remaining precipitate is sintered to crystallize the particles. During sintering, the surfactant is decomposed to form a carbon network between the crystallized particles and the crystallized particles and the carbon matrix are integrated to form the electrode material.
