Great interest in lithium iron phosphate (LFP) technology for rechargeable batteries
3/15/2012
Muttenz/Switzerland, 14.03.2012 - LiFePO4+C Licensing AG in Muttenz (Switzerland) has closed a sublicensing agreement granting to BASF rights to use key patents for the production and marketing of lithium metal phosphates (LMPs), and in particular lithium iron phosphate (LFP). LMP/LFP is an innovative cathode material whose excellent performance and superior safety profile make it the ideal choice, particularly for lithium ion batteries used in stationary applications and in the automotive industry.
The three patent holders, Hydro-Quebec (Canada), Universite de Montreal (Canada) and the Centre National de la Recherche Scientifique (CNRS - France), in association with Clariant subsidiary Sud-Chemie, reached an agreement in 2011 to grant a limited number of sublicenses in this technology through LiFePO4+C Licensing AG in order to address rapidly growing demand for reliable and authorized sources of LFP from battery producers and auto makers.
A licensing agreement for the manufacturing and sale of LMP/LFP exists between the patent holders and Sud-Chemie which has its own industrial LFP producing operations. There are also sublicense agreements between LiFePO4+C Licensing AG and two Japanese firms, Sumitomo Osaka Cement Co. Ltd. and Mitsui Engineering & Shipbuilding Co. Ltd. as well as with two Taiwanese companies, Tatung Fine Chemicals Co. and Advanced Lithium Electrochemistry (Cayman) Co. Ltd (ALEEES). Japan's Sony Corporation and the American corporation A123 Systems Inc. both hold licenses to manufacture LMP/LFP for use in its own battery production.
The BASF decision to opt for LMP/LFP technology lends additional impetus to the swift and widespread market penetration of LMP/LFP materials.
About LFP Technology
Lithium iron phosphate (LiFePO4, LFP) is a novel cathode material that, due to its high performance and unsurpassed safety profile, has a great deal of potential for use in next-generation lithium ion batteries, used among other things for hybrid and electric drives in the automotive industry and for stationary energy storage, for instance in solar energy. LFP material was discovered at the University of Texas in Austin in 1995 and licensed to Hydro-Quebec. When LFP material is coated with a thin layer of carbon, its conductivity is enhanced allowing LFP's unique performances. Such layer must be thin enough in order to permit lithium to pass through. These inventions were protected through the LFP carbon coating patents and the LFP carbon coating process patents co-owned by Hydro-Quebec, Canada, Universite de Montreal, Canada, and Centre National de la Recherche Scientifique (CNRS), France.

The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
