20140034864 | COMPOSITION FOR EXTINGUISHING AND/OR INHIBITING FIRES THAT CONTAIN FLUORINE AND/OR PHOSPHORUS - A fire-extinguishing and/or fire-inhibiting composition is based on polymers capable of swelling. In order to bind fumes containing fluorine and/or phosphorous, for example in the event of fires of lithium-ion batteries, the composition includes at least one alkaline-earth carboxylate, in particular calcium carboxylate, of one or more carboxylic acids. | 02-06-2014 |
20140034865 | COMPOSITION FOR EXTINGUISHING AND/OR RETARDING FIRES CONTAINING FLUORINE AND/OR PHOSPHORUS - A fire-extinguishing and/or fire-retarding composition is based on swellable polymers. In the event of fires of lithium ion batteries, smoke gases containing fluorine and/or phosphorus are bound using alkaline earth metal ions, more particularly calcium ions. | 02-06-2014 |
20140170447 | BATTERY HOUSING FOR LITHIUM-ION CELLS - A battery housing includes an inner chamber configured to accommodate galvanic cells, in particular lithium-ion cells, which are provided with a cut-out area that can be opened in the event of failure of the cell. In order to prevent, retard and optionally at least partially extinguish a fire in the event of the failure of one or more cells, for example during an accident of an electrically operated vehicle, the inner chamber of the battery housing includes at least one dispenser for dispensing a flame-inhibiting, flame-retarding and/or flame-extinguishing agent. The dispenser has at least one dispenser opening arranged adjacent to a cut-out area of a cell and configured to be opened. The dispenser opening is configured to be opened during a mechanical shock and/or a temperature increase and/or a pressure increase above a predetermined limit value. | 06-19-2014 |
