Lightweight, low resistance, thin plate for lead-acid electrochemical cells formed primarily of an aluminum foil substrate having a thickness of between about 0.005 inches and 0.030 inches, and a continuous outer layer of lead or lead alloy having a thickness of less than about 0.005 inches and that is corrosive resistant to the electrolytic acid of the battery.

Lightweight, low resistance electrode plate for lead-acid batteries

Lightweight, low resistance electrode plates for lead-acid batteries are formed from a highly conductive non-lead substrate with a corrosion prevention layer and a continuous layer of a corrosive resistant conductive materials, such as lead, applied from a fused salt bath.

High energy, lightweight, lead-acid storage battery

Light weight, low resistance electrode plates for lead-acid batteries are formed from a highly conductive non-lead substrate such as aluminum or copper, coated with a continuous layer of a corrosive resistant conductive materials, such as lead, applied from a fused salt bath.

High energy, light weight, lead-acid storage battery

A lightweight, high-energy electrode plate for a lead acid battery, and method for making an electrode plate, comprising a highly conductive non-lead substrate having a specific gravity no greater than 70% that of lead, a pair of outer layers of thin sheets of imperforate conductive foil that is corrosive resistant to the electrolyte acids of the battery and that are welded together to encapsulate the non-lead substrate.

Foil-encapsulated, lightweight, high energy electrodes for lead-acid batteries

A battery-plate separator system includes three layers in face-to-face relationship, the first and third layers including a porous mat of randomly oriented fibers, and, between the first and third layers, a second layer comprising a porous organic polymeric sheet with tortuosity and pores sufficiently small to substantially block penetration by metallic particles. A storage battery includes a plurality of positive lead peroxide elec-trodes, a plurality of negative metallic lead electrodes, and the same three-layer separator system in a closed case with a body of electrolyte to which the system is inert, that is absorbed by the separator system, and that is maintained in contact with the electrodes.

Storage battery and plate separator systems for a storage battery

A lead-acid aircraft battery including an electric terminal assembly for making connections to the internal electrodes of the battery, the terminal assembly being embedded in the plastic cover of the battery and effectively sealed to the cover so as to prevent corrosion by the acid electrolyte in the battery. In a first embodiment the terminal assembly includes a pair of threaded terminal posts which extend outwardly from the cover; and a receptacle; including a corresponding pair of terminal pins respectively threaded coaxially to the posts, is attached to the cover by screws. In a second embodiment an Elcon type receptacle is molded directly into the cover.

Aircraft battery

A molded plastic receptacle for a lead-acid aircraft battery, or the like, which is adapted to be mounted on the side wall of the battery comprising threaded pin terminals which extend through the receptacle and which are molded to the receptacle. The receptacle is formed of a polycarbonate thermoplastic resin which is sufficiently strong to permit the receptacle to be mounted on the side wall of the battery by screws extending through holes in the receptacle and without any need to provide metal bushings in the holes.

Terminal support member

A nonspill vented closure assembly is provided for a wet cell type of storage battery which normally provides a venting hole to the interior of the battery, and which includes a tiltable weight that lifts a valve to close the vent hole whenever the battery is tilted with respect to the vertical beyond a certain angular displacement, so as to prevent leakage of the liquid electrolyte through the closure assembly. The closure assembly includes a tubular casing which is threaded into the normal fill hole of the battery. A lead weight which constitutes the tiltable mass is supported in the casing. A valve stem connects the lead weight to a valve member, and it serves to move the valve member against an annular valve seat surrounding an orifice in the lower end of the casing whenever the lead weight is tilted. The valve stem includes a ball at its upper end which extends into a cavity in the bottom of the lead weight, and which is held in the cavity by a plastic disc which forms a bearing surface for the ball. A cover is mounted on the other end of the casing, and a vent hole extends through the cover. A hydrophobic porous filter is mounted under the cover, and this filter forms a secondary barrier for preventing any liquid electrolyte from leaking through the vent. The casing is provided with an internal sloping shelf which supports the lead weight, the shelf having internal channels which serve as drainage means to permit and facilitate the free flow back into the interior of the battery of any liquid electrolyte in the closure assembly.
