A lead-acid battery comprises a flame arrestor plug (1) for controlled venting of gases from the battery through the vent hole (3), wherein the flame arrestor plug has a valve element (5) for controlling the venting of gas from the vent hole and a plug portion (4) which is adjacent to or in contact with the battery casing (2) around the vent hole and which, together with the battery casing, defines a flow path through which gases released through the valve element can escape from the battery, at least a portion of the flow path being of sufficiently narrow cross-section to prevent propagation of a flame along the flow path.
An improved emergency power system is disclosed for providing electrical power to a load such as a blowout preventer of a petroleum drilling apparatus. The improved emergency power system comprises a thermal battery having an anode and a cathode with a separator containing an electrolyte disposed therebetween. An internal heat layer is located in proximity to the separator containing the electrolyte. A squib is provided for activating the internal heat layer. The thermal battery remains dormant until the squib is energized to ignite the squib enabling the heat layer to render the electrolyte molten thereby activating battery to provide electrical power to the load. The squib may be energized remotely, mechanically or electrically.
A battery is disclosed. The battery includes an electrolyte activating one or more anodes and one or more cathodes. The electrolyte includes one or more salts dissolved in a solvent. The solvent includes one or more first siloxanes and/or one or more first silanes. Each of the first siloxanes and/or first silanes have one or more first substituents that each include a poly(alkylene oxide) moiety. The solvent also includes one or more second siloxanes and/or one or more second silanes. Each of the second siloxanes and/or second silanes have one or more second substituents that each include a carbonate moiety.
The electrochemical device assembly includes an anode tab in electrical communication with one or more anodes. The anode tab includes a first material. The assembly also includes a spacer having a third material and a fourth material. The third material is connected to the first material of the anode tab. The assembly also includes a cathode tab in electrical communication with one or more cathodes. The cathode tab includes a second material connected to the fourth material of the spacer. The second material is different from the first material and the fourth material is different from the third material.
Disclosed is an electric storage battery and method of making it, comprising a jellyroll electrode assembly in which electrodes are wound around a pin, and having one or more spacers at or near the inner ends of the electrodes to aid in winding the jellyroll. Also disclosed is an electric storage battery, and method of making it, comprising a jellyroll electrode assembly in which electrodes are wound around a pin, and having a plastic slotted tube closely fitted around the pin and covering the junction of the pin to an electrode substrate or interface material coupled to the electrode substrate. The spacers and plastic slotted tube may be used separately or together.
A battery includes a case having an interior holding an electrolyte activating one or more anodes and one or more cathodes. A cover is positioned on the case. The cover includes one or more quenching media that each has a phase transition that occurs at a temperature above a failure temperature of the battery and below a failure temperature of the battery. The failure temperature is the temperature at which a chain reaction associated with thermal runaway is initiated. The failure temperature of the battery is the temperature of the battery at which the thermal runaway causes failure of the battery.

The battery includes a cover assembly on a battery case. The cover assembly includes a battery cover coupled with an electrically insulating flap of material. The battery can include a first electrical connector that provides electrical communication between a terminal in the cover and one or more first electrodes in the battery. The first connector is at least partially positioned between a first region of the flap and a second region of the flap. The battery can also includes a second electrical connector that provides electrical communication between the cover and one or more second electrodes in the battery. The second connector passes between the flap and the case such that a portion of the flap is between the first connector and the second connector.
An electrode system includes one or more separator materials formed into a bag having at least two seams. The seams are positioned so as to define the perimeter of a pocket configured to receive an electrode within the bag. At least one gap is formed between seams adjacent to one another along the perimeter of the pocket. Additionally, at least one of the seams includes a spacer positioned between portions of the one or more separator materials joined by the at least one seam.
The invention relates to a method of operating a lead acid battery which undergoes discharging phases and charging phases in a cyclical fashion. The method involves monitoring the current discharged from the battery during a discharging phase and recording information relating to that current flow, such as the charge lost from the battery. During the subsequent charging phase, a desired amount of charge to be supplied to the battery is calculated based upon the recorded information, and then supplied to the battery.

Pack assembly having interconnected battery packs configured to be individually disconnected from assembly
A battery pack system is disclosed. The battery pack system includes a battery pack having batteries arranged in a plurality of parallel groups that are connected in series. Each parallel group includes a plurality of the batteries connected in parallel. The electronics are configured to drop the current at which the battery pack is operating from a first current level to a second current level one or more times. The second current level is lower than the first current level. The electronics can drop the current from the first current level to the second current level during the charge and/or discharge of the battery pack. In some instances, the electronics intermittently drop the current from the first current level to the second current level during the charge and/or discharge of the battery pack.
