Abstract: Embodiments of the disclosed lithium ion rechargeable battery include an anode, a cathode, and a separator including an electrolyte to prevent physical contact between the anode and the cathode, while also providing medium for transporting the lithium ions. In some embodiments, the anode may include a microporous scaffold structure that includes a silicon crystal covered in a thin polycrystalline silicon cover. Additionally, the various embodiments described herein further describe increasing the surface area of the microporous scaffold structure so as to provide a more efficient charge flow between the anode and the cathode. In some embodiment, the two or more microporous scaffold structures are stacked on top of one another so that there is an increase in contact area and reduced contact resistance, thus further increasing the charge capacity of the disclosed lithium ion rechargeable battery.

Abstract: A downhole rotational rate control apparatus is disclosed, adapted for coupling to the lower end of a drill string, and includes a progressive cavity (PC) pump or motor, multiple fluid flow paths, and a flow control valve for controlling fluid flow in the flow paths. Drilling mud flowing downward through the drill string is partially diverted to flow through the PC pump or motor and, in turn, the PC pump or motor speed is controlled by the flow control valve. The control valve can be actuated by a control motor in response to inputs from a sensor assembly in an electronics section. The PC pump or motor drives a controlled downhole device at a specific zero or non-zero rotational rate. By varying the rotational rate of the PC pump or motor relative to the rotational rate of the drill string, the tool face orientation or non-zero rotational speed of the controlled device in either direction can be varied in a controlled manner.

Abstract: In a mud-lubricated bearing assembly for a downhole motor, a mechanical seal is provided between the mandrel and the lower end of the bearing housing to prevent discharge of drilling fluid (mud) from the bearing assembly into the wellbore annulus. The mechanical seal is effected by mating wear-resistant annular contact surfaces provided on the mandrel and the bearing housing, with biasing means preferably being provided to keep the contact surfaces in sealing engagement during both on-bottom and off-bottom operational modes. The diverted drilling fluid passing through the bearings is redirected into the bore of the mandrel via ports through the mandrel wall to rejoin the main flow to the drill bit, such that substantially all of the drilling fluid flows through the bit.
