US 4,049,891 COMPOSITIONS FOR FAST ALKALI-METAL-ION TRANSPORT – Goodenough, John B.; Hong, Henry Y-P; September 20, 1977
Fast alkali-metal-ion transporters are provided having low resistivities and low-activation-energy mobilities at temperatures at which alkali metals are molten. The novel compounds promote alkali-metal-ion transport in three dimensions within their crystalline structure and have the general formula: or wherein A is potassium, sodium or lithium, Z' is a tetrahedrally coordinated cation or mixtures thereof, X is an octahedrally coordinated cation or mixtures thereof, n is a number greater than 1 and less than 4, m is a number from 1 up to 2 and Z' is a mixture of at least two Z' cations.

US 4,302,518 ELECTROCHEMICAL CELL WITH NEW FAST ION CONDUCTORS – Goodenough John B.; Mizushima, Koichi; November 24, 1981
There is interest in the use of solid-solution electrodes as a way of meeting the problems of conventional batteries; Li.sub.a TiS.sub.2 where O<a<1 is known in this respect and may be made by high temperature preparative routes. Fast ion conductors of the formula A.sub.x M.sub.y O.sub.2 where A is Li, Na or K, M is a transition metal e.g. Co or Ni, <x<1 and y.apprxeq.1 have been made for this purpose according to the invention. They cannot be made by high temperature routes when x is substantially less than 1 owing to stability problems. In the invention, they have been made by electrochemical extraction of A.sup.+ ions from compounds of the formula A.sub.x' M.sub.y O.sub.2 where O<x'<1, carried out at low temperature.

US 4,357,215 FAST ION CONDUCTORS – Goodenough, John B.; Mizushima, Koichi; November 2, 1982
There is interest in the use of solid-solution electrodes as a way of meeting the problems of conventional batteries; Li.sub.a TiS.sub.2 where O.ltoreq.a.ltoreq.1 is known in this respect and may be made by high temperature preparative routes. Fast ion conductors of the formula A.sub.x M.sub.y O.sub.2 where A is Li, Na or K, M is a transition metal e.g. Co or Ni, .ltoreq.x<1 and y.apprxeq.1 have been made for this purpose according to the invention. They cannot be made by high temperature routes when x is substantially less than 1 owing to stability problems. In the invention, they have been made by electrochemical extraction of A.sup.+ ions from compounds of the formula A.sub.x' M.sub.y O.sub.2 where O<x'.ltoreq.1, carried out at low temperature.

US 4,507,371 SOLID STATE CELL WHEREIN AN ANODE, SOLID ELECTROLYTE AND CATHODE EACH COMPRISE A CUBIC-CLOSE-PACKED FRAMEWORK STRUCTURE – Goodenough, John B; Thackeray, Michael M.; March 26, 1985
The invention provides an electrochemical cell wherein an anode, solid electrolyte and cathode each comprise a cubic-close-packed framework structure having, as its basic structural unit, a unit of the formula (B.sub.2)X.sub.4.sup.n- which is the structural unit of an A(B.sub.2)X.sub.4 spinel. The structure accommodates active cations M.sup.+ capable of diffusion therethrough. The invention also extends to electrodes and electrolytes of the above type for use in such cells.

US 5,910,382 CATHODE MATERIALS FOR SECONDARY (RECHARGEABLE) LITHIUM BATTERIES – Goodenough, John B.; Padhi, Akshaya K.; Nanjundaswamy, K. S.; Masquelier, Christian; June 8, 1999
The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery. The invention provides transition-metal compounds having the ordered-olivine or the rhombohedral NASICON structure and the polyanion (PO.sub.4).sup.3- as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.

US 6,221,812 JC IN HIGH MAGNETIC FIELD OF BI-LAYER AND MULTI-LAYER STRUCTURES FOR HIGH TEMPERATURE SUPERCONDUCTIVE MATERIALS – Goodenough, John B.; Zhou, JiPing; McDevitt, John T.; April 24, 2001
To improve the chemical stability, as well as the critical current density (J.sub.C) of a superconductive material in an external magnetic field, copper-oxide coating materials have been developed. In some embodiments, these coating materials include a composition with the formula R.sub.1-x Ca.sub.x Ba.sub.2-y La.sub.y Cu.sub.3-z M.sub.z O.sub.7-.delta., where R is a rare-earth element (e.g., La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, or Y), M is a transition metal (e.g., Mn, Re, Fe, Os, Co, Rh, Ir, Ni, Pd, Pt, Ag, Au, Zn, Cd, or Hg), 0.ltoreq.x.ltoreq.0.4, 0.ltoreq.y.ltoreq.0.4, and 0.ltoreq.z.ltoreq.1.0. These coating materials are preferably used as a surface layer on superconductive materials to impart corrosion resistance and an improved critical current density when the layers are exposed to magnetic fields.


US 6,391,493 CATHODE MATERIALS FOR SECONDARY (RECHARGEABLE) LITHIUM BATTERIES – Goodenough, John B; Padhi, Akshaya K.; Nanjundaswamy, K. S.; Masquelier, Christian; May 21, 2002
The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery. The invention provides transition-metal compounds having the ordered-olivine or the rhombohedral NASICON structure and the polyanion (PO.sub.4).sup.3- as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.

US 6,514,640 CATHODE MATERIALS FOR SECONDARY (RECHARGEABLE) LITHIUM BATTERIES – Goodenough, John B.; Armand, Michel; Padhi, Akshaya K.; Nanjundaswamy, Kirakodu S.; Masquelier, Christian; February 4, 2003
The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery.
