20090269667 | Porous Electrically Conductive Carbon Material And Uses Thereof - This disclosure relates to a porous electrically conductive carbon material having interconnected pores in first and second size ranges from 10 μm to 100 nm and from less than 100 nm to 3 nm and a graphene structure and to diverse uses of the material such as an electrode in a lithium-ion battery and a catalyst support, e.g. for the oxidation of methanol in a fuel cell. The carbon material has been heat treated to effect conversion to non-graphitic carbon with the required degree of order at a temperature in the range from 600° C. to 1000° C. A lithium-ion battery and an electrode for a lithium-ion battery are also claimed. | 10-29-2009 |
20100210453 | Preparation Of Nanostructured Metals And Metal Compounds And Their Uses - A method for the preparation of materials comprises the steps of: a) taking a first material comprising a compound of a first metal or of a first metal alloy, b) inserting said first material into an electrochemical cell as a first electrode, the electrochemical cell including a second electrode including a second metal different from a metal incorporated in the first material and an electrolyte adapted to transport the second metal to the first electrode and insert it into the first material by a current flowing in an external circuit resulting in the formation of a compound of the second metal in the first electrode material, the method being characterized by the step of treating the first electrode material after formation of the compound of the second metal to chemically remove at least some of the compound of the second metal to leave a material with a nanoporous structure. | 08-19-2010 |
20140205867 | APPARATUS AND METHOD FOR PROVIDING SAFETY MEASURES DURING GAS RELEASE FROM A VEHICLE BATTERY AND INSTALLATION SPACE FOR A VEHICLE BATTERY - An apparatus for providing safety measures during gas release from a vehicle battery, such as a damaged lithium-ion rechargeable battery, arranged in a volume space having an opening includes at least one shroud element. The shroud element is configured to expand into the volume space by being filled with a gas such that, upon expansion of the shroud element, openings in the shroud element are enlarged and shroud element contents are discharged into the volume space through the enlarged openings in the shroud element. The apparatus further includes a device that, upon reception of a trigger signal, is configured to fill the shroud element at least partially with carbon dioxide gas such that carbon dioxide gas is discharged into the volume space as contents of the shroud element. An installation space includes the apparatus and a method is implemented to provide safety measures during gas release from the vehicle battery. | 07-24-2014 |
20140329115 | BATTERY HAVING A COVER THAT HAS PREDETERMINED BREAKING POINTS - A battery includes at least two battery cells arranged adjacent to one another and each arranged in a battery cell housing. Each battery cell has at least one battery cell terminal. The battery also includes one degasification element per battery cell. Each degasification element is arranged within the battery cell housing associated with the respective battery cell and is configured to discharge gases generated within the respective battery cell from the respective battery cell in the presence of a predetermined gas pressure. The battery also includes a cover configured to cover at least a part of the surfaces of the battery cells and cover the degasification elements of the battery cells in air-tight fashion. The cover has, in each case in a region of the degasification elements, predetermined breaking points assigned to the degasification elements. | 11-06-2014 |
20140363705 | Lithium Ion Battery Cell having a Capacitance Sensor and Method for Monitoring the Condition of a Lithium Ion Battery Cell of this Type - A lithium ion battery cell includes a graphite cathode, and an excess pressure valve. The excess pressure valve is configured to open in the presence of a predetermined battery cell internal pressure and discharging gases that have been produced inside the battery cell. Such gases are discharged together with graphite particles entrained in the gas. The battery cell further includes a capacitance sensor that has at least one capacitor positioned in the battery cell and configured such that the graphite particles that are entrained in the gas that is being discharged deposit themselves at least in part in a gap that is located between two electrodes of the capacitor and cause a change in the dielectric value in the gap. The change in the dielectric value causes a change in a capacitance of the capacitor. | 12-11-2014 |
