标 题 :Method for the synchronous absorption of carbon dioxide from flue gas and synthesis of dialkyl carbonates and alkylene carbonates

摘要:The invention relates to a synchronous CCU method (carbon dioxide capture and utilisation) for the absorption of carbon dioxide from flue gas and other CO 2 -containing substance sources and simultaneous synthesis of dialkyl carbonates and alkylene carbonates. The general subject matter of the invention is, in terms of a 'carbon dioxide capture' on the one hand, the absorption of CO 2 from flue gas and other CO 2 -containing substance sources with ammonia and/or amines to form ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates and, in terms of a 'carbon dioxide utilisation' on the other hand, the reaction of ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates with aliphatic, alicyclic or unsaturated alcohols, and including unsaturated aromatic alcohols to give dialkyl carbonates or alkylene carbonates in such a form that the CO 2 n absorption agent is re-released and fed back into the repetitive process again. A repetitive process control is extremely energy and CO 2 n efficient.

摘要:At the time of synthesis of lithium nickelate, by adding a firing aid to material to be fired, crystal growth is promoted at a temperature that is lower than a firing temperature necessary for obtaining desired crystal growth of lithium nickelate, and substitution of elements that contribute to structural stability in crystals is promoted. Furthermore, distortion of crystal or loss of oxygen at the time of synthesis is suppressed. Thus, a lithium ion secondary battery having excellent charge and discharge characteristics and cycling characteristics can be provided.

标题:Synthesis of carbon/silicon composites
发明人：GROSS KARL J; WANG JAMES C F; ROBERTS GREGORY A
摘要:The present embodiment relates to a method for preparing a composite graphite-silicon negative electrode material whereby an essentially dry mixture of graphite carbon powder and an element or elements selected from the new IUPAC Group Number 12-15 of the Periodic Table of Elements that can form alloys or compounds with lithium is prepared to provide an electrochemically active mixture. A mechanical agitation process serves to mix the constituent materials and to produce a fine dispersion with intimate contact between graphite and the Group 12-15 materials. A lithium ion battery negative electrode of this composition takes synergistic advantage of the high lithium capacity of some IUPAC Group materials and the long cycle-life of graphite negative electrode materials.
