Publication number: 20210242449Abstract: A flooded lead acid battery and a vehicle comprising the same are described herein. The flooded lead acid battery comprises an electrode array, comprising one or more negative plates and one or more positive plates alternately arranged and interleafed with one another. In some embodiments, a negative plate is wrapped or enveloped with a fibrous mat, and a porous membrane is wrapped or enveloped about an adjacent positive electrode. In some embodiments, a fibrous mat is at least partially integrated into a negative plate, and a porous membrane is enveloped about either the negative plate with the fibrous mat partially integrated therein or around an adjacent positive plate. In other embodiments, a negative plate is enveloped with a porous membrane having ribs, and a fibrous mat is present between the wrapped negative plate and the porous membrane enveloping the negative plate. Methods, systems, and vehicles utilizing the disclosed batteries are also provided.Type: ApplicationFiled: April 18, 2019Publication date: August 5, 2021Inventors: Jorg Deiters, Matthew Stainer, Anna L.
