| 20120003508 | BATTERY OF ELECTROCHEMICAL GENERATORS COMPRISING A FOAM AS INTER-GENERATOR FILLER MATERIAL - A battery of lithium electrochemical generators including a casing; a plurality of lithium electrochemical generators housed in the casing, each generator including a container; a rigid, flame-retardant foam with closed porosity formed of an electrically insulating material filling the space between the inner wall of the casing and the free surface of the side wall of the container of each electrochemical generator, the foam covering the free surface of the side wall of the container of each electrochemical generator over a length representing at least 25% of the height of the container. | 01-05-2012 |
| 20110318636 | ACTIVE MATERIAL OF A NICKEL-CADMIUM GENERATOR NEGATIVE ELECTRODE - The hydration of cadmium oxide in the presence of nickel acetate gives the possibility of obtaining a compound of general formula Cd | 12-29-2011 |
| 20110307202 | SYSTEM FOR MONITORING THE STATE OF A BATTERY - The invention is a monitoring system for a battery having a plurality of accumulators. The system comprises means for measuring the voltage on the terminals of each accumulator, means for measuring the temperature of the battery, means for measuring the current flowing through the battery, means for calculating a voltage difference between a maximum voltage measured on the terminals of one of the accumulators and a minimum voltage measured on the terminals of one of the accumulators, means for comparing the voltage difference with at least one threshold value depending on the measured temperature and current, and means reporting an error if the voltage difference is greater than or equal to said at least one threshold value. | 12-15-2011 |
| 20110223449 | SAFETY DEVICE FOR A SEALED CELL - A safety device for a sealed cell ( | 09-15-2011 |
| 20100261052 | PLASTICIZED ELECTRODE FOR AN ALKALINE BATTERY - An electrode including a conductive metal support and a paste including an electrochemically-active material and a binder. The binder includes a compound of silane type, and a polymer having at least one acrylic monomer, and representing at least approximately 0.15% of the weight of said paste. The use of this binder improves the calendar or cycle life of the battery at a temperature greater than or equal to 25° C., preferably at a temperature greater than or equal to 40° C. | 10-14-2010 |
| 20090206302 | HYDROGEN-ABSORBING ALLOY FOR AN ALKALINE STORAGE BATTERY - Therefore the invention provides a hydrogen-absorbing alloy comprising at least one A | 08-20-2009 |
| 20080254354 | CONNECTION SYSTEM FOR AN ELECTROCHEMICAL CELL - An electrochemical cell includes a can and a jelly roll disposed in the can. The jelly roll includes a positive electrode and a negative electrode, wherein positive winding foils protrude from a positive end of the jelly roll and negative winding foils protrude from a negative end of the jelly roll. The positive winding foils are folded in a same direction to overlap each other in a first pattern of recesses and the negative winding foils are folded in a same direction to overlap each other in a second pattern of recesses. A positive disk includes a plurality of leg forms welded into the first pattern of recesses formed in the positive winding foils. A negative disk includes a plurality of leg forms welded into the second pattern of recesses formed in the winding foils. At least one of the positive disk and the negative disk is electrically insulated from the can. | 10-16-2008 |
