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. (4254 Drake Way, Livermore, CA 94550); Guidotti, Ronald A [3019 Florida St. NE., Albuquerque, NM 87110]

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
