Abstract: An electrode assembly includes a first substrate, a first active material composite coating the first substrate, a first electrode tab is formed by an uncoated portion of the first substrate that extends continuously between a first end and a second end of the first substrate. The assembly further includes a second elongate substrate, a second active material composite coating the second substrate, and a second electrode tab formed by an uncoated portion of the second substrate that extends continuously between a first end and a second end of the second substrate. An electrically-insulative separator is between the first substrate and the second substrate. The first substrate and second substrate, stacked together with the separator located between them, are then rolled about a central axis to form a jelly roll.

Abstract: A method of manufacturing a current collector comprising embossing a sheet comprising lead thereby forming an embossed grid comprising rows of raised portions and lowered portions, and slots comprising edges of the raised portions and lowered portions; creating areas for tab creation by pressing or stamping areas of the embossed grid to a flattened state, thereby forming a sheet comprising embossed grid sections and flat sections; applying paste to the top and bottom of the embossed grid sections; and stamping current collectors out of the sheet such that at least one tab is created from a flat section.

Abstract: An electrode includes a current collector comprising a grid, said grid comprising a plurality of planar, parallel rows disposed between interleaved rows having raised and lowered segments, and a tab portion extending from a side of the current collector. Raised and lowered segments are disposed horizontally relative to the tab portion, thereby providing substantially uninterrupted conductive ribbons extending from the bottom of the current collector to the tab portion.

Abstract: A negative electrode for a hybrid energy storage device includes a current collector; a corrosion-resistant conductive coating secured to at least one face of the current collector; a sheet comprising activated carbon adhered to the corrosion-resistant conductive coating; a tab portion extending from a side of the negative electrode; and a lug comprising a lead or lead alloy that encapsulates at least part of the tab portion.

Abstract: A hybrid supercapacitor energy storage device includes at least one lead electrode, at least one carbon electrode, a separator, a casing, and an acid electrolyte. The lead electrode is enveloped in a common glass mat separator known in the lead-acid battery industry. The carbon electrode comprises a highly conductive current collector which is a sheet or other metal material sandwiched between two sheets of electronically conductive shield material. Activated carbon is manufactured using a binder such as polyethylene or PTFE adhered to and in electrical contact with the shield material of the current collector.

Abstract: Management control system for managing an energy supply and storage system for a rig power supply of the type having a power generator coupled to rig loads, the power generator used for powering the rig and for charging the storage system, and the storage system adapted for selectively supplementing rig power, is adapted for controlling the selection of rig function operation, for setting the system to recommended settings for the selected rig function operation, for monitoring rig power usage for the selected rig function operation for distributing excess power to the storage system when the rig power usage falls below a preselected threshold, and for distributing stored power from the storage system when the rig power usage is above a preselected threshold. The recommended setting for the selected rig function may be modified depending upon power usage by setting preselected thresholds.

Abstract: An energy supply and storage system for a rig power supply system is disclosed for a rig power supply system of the type having a power generator coupled to rig loads and motors via a bus. The energy supply and storage device is a power supply in parallel with the rig motors and adapted for receiving energy generated by the generator in excess of demand. The energy storage system is in communication with the power supply for receiving and storing the excess energy, with the power supply being adapted to draw energy from the storage system when the rig motor demand exceeds the capacity of the generator.

Abstract: An energy storage device includes at least one positive electrode comprising a current collector comprising lead and having a plurality of raised and lowered portions with respect to a mean plane of the current collector and slots formed between the raised and lowered portions, wherein lead dioxide paste is adhered to and in electrical contact with the surfaces thereof; and a tab portion; and at least one negative electrode comprising a carbon material.

Abstract: A hybrid energy storage device has at least one lead-based positive electrode and at least one carbon-based negative electrode, a separator between the electrodes, a casing which will contain the electrodes and separator, and an acid electrolyte. The separator is gas permeable, and is capable of absorbing and entraining acid electrolyte. The separator has a finite capacity for absorption of acid electrolyte, and the quantity of acid electrolyte which is present in the cell is less than the finite capacity of the separator. Upon assembly of the cell, the casing is sealed, and there is no liquid acid electrolyte within the assembled cell.
