Abstract

A prefabricated carbon anode containing predetermined amounts of passivating film components is assembled into a lithium-ion rechargeable battery. The modified carbon anode enhances the reduction of the irreversible capacity loss during the first discharge of a cathode-loaded cell. The passivating film components, such as Li.sub.2 O and Li.sub.2 CO.sub.3, of a predetermined amount effective for optimal passivation of carbon, are incorporated into carbon anode materials to produce dry anodes that are essentially free of battery electrolyte prior to battery assembly.

Lithium intercalation carbon and method for producing same

Patent Even, Jr., William R. ; Guidotti, Ronald A.

Disordered carbons were synthesized at 700.degree. C. from methacrylonitrile-divinylbenzene precursors. The disorder, even at the free surface, was confirmed with TEM. These powdered carbons were subjected to rapid surface heating by a pulsed infrared laser (59 MW pulses). While the bulk structure remained essentially unchanged, there was substantial "surface reconstruction" to a depth of 0.25 .mu.m presumably due to ablation, re-deposition, and "recrystallization" of the surface carbon after heating by the laser. The surface ordering appears similar to the bulk microstructure of carbons isothermally annealed at 2,200.degree. C. (i.e., turbostatic). Improvements were observed in first cycle irreversible loss, rate capability,more »« less

Protective lithium ion conducting ceramic coating for lithium metal anodes and associate method

Patent Bates, John B.

A battery structure including a cathode, a lithium metal anode and an electrolyte disposed between the lithium anode and the cathode utilizes a thin-film layer of lithium phosphorus oxynitride overlying so as to coat the lithium anode and thereby separate the lithium anode from the electrolyte. If desired, a preliminary layer of lithium nitride may be coated upon the lithium anode before the lithium phosphorous oxynitride is, in turn, coated upon the lithium anode so that the separation of the anode and the electrolyte is further enhanced. By coating the lithium anode with this material lay-up, the life of themore »« less

Plasma synthesis of lithium based intercalation powders for solid polymer electrolyte batteries

Patent Kong, Peter C ; Pink, Robert J ; Nelson, Lee O

The invention relates to a process for preparing lithium intercalation compounds by plasma reaction comprising the steps of: forming a feed solution by mixing lithium nitrate or lithium hydroxide or lithium oxide and the required metal nitrate or metal hydroxide or metal oxide and between 10-50% alcohol by weight; mixing the feed solution with O.sub.2 gas wherein the O.sub.2 gas atomizes the feed solution into fine reactant droplets, inserting the atomized feed solution into a plasma reactor to form an intercalation powder; and if desired, heating the resulting powder to from a very pure single phase product.
