Patent application number | Description | Published |
20090253041 | FLOODED LEAD-ACID BATTERY AND METHOD OF MAKING THE SAME - Positive active material pastes for flooded deep discharge lead-acid batteries, methods of making the same and lead-acid batteries including the same are provided. The positive active material paste includes lead oxide, a sulfate additive, and an aqueous acid. The positive active material paste contains from about 0.1 to about 1.0 wt % of the sulfate additive. Batteries using such positive active material pastes exhibit greatly improved performance over batteries with conventional positive active material pastes. | 10-08-2009 |
20110027653 | NEGATIVE PLATE FOR LEAD ACID BATTERY - Capacitor pastes for flooded deep discharge lead-acid batteries include lead oxide, a carbon additive, and an aqueous acid. The capacitor paste contains lead and carbon in a lead to carbon mass ratio of about 5:1 to 82:1. Hybrid negative plates for flooded deep discharge lead-acid batteries can be made using such pastes in combination with traditional pastes. The hybrid negative plates include a capacitor paste on a bottom portion of the plate, and a traditional paste on the remainder of the plate. Batteries using the capacitor paste and hybrid plates exhibit improved performance over batteries with conventional plates and pastes and require less overcharge to prevent electrolyte stratification. | 02-03-2011 |
20110250500 | POSITIVE ACTIVE MATERIAL FOR A LEAD-ACID BATTERY - Positive active material pastes for flooded deep discharge lead-acid batteries, methods of making the same, and lead-acid batteries including the same are provided. The positive active material paste includes a lead compound, a carbon additive, and a silicon additive. The positive active material paste contains carbon additive at a lead to carbon additive weight ratio of 90 to 1900 and a silicon additive at a lead to silicon additive weight ratio of 200 to 4100. | 10-13-2011 |
20110318629 | SEPARATOR FOR LEAD ACID BATTERY - Separators for lead-acid batteries, and lead-acid batteries including the same are provided. The separator includes a first layer made of a rubber material and a second layer made of a polymer material. | 12-29-2011 |
20120058369 | SYSTEM AND METHOD FOR DELIVERING FLUID TO A BATTERY - A system for delivering water to a fluid electrolyte battery comprising at least one battery cell. Such a system includes a tank adapted to hold the fluid, a pump adapted to pump the fluid from the tank when the pump is turned on, at least one conduit adapted to transfer the fluid from the tank to the at least one battery cell, and a controller adapted to control the pump. The controller turns the pump on after an interval so that the fluid is transferred to the at least one battery cell. | 03-08-2012 |
20130149611 | FLOODED LEAD-ACID BATTERY AND METHOD OF MAKING THE SAME - Positive active material pastes for flooded deep discharge lead-acid batteries, methods of making the same and lead-acid batteries including the same are provided. The positive active material paste includes lead oxide, a sulfate additive, and an aqueous acid. The positive active material paste contains from about 0.1 to about 1.0 wt % of the sulfate additive. Batteries using such positive active material pastes exhibit greatly improved performance over batteries with conventional positive active material pastes. | 06-13-2013 |
