Abstract : The objective of the project was the discovery of new materials which might be useful as superconductors, useful in superconducting devices, or useful in other electronic applications. Some insulating cuprates have been converted to superconductors by intercalation with oxygen, e.g., La2CuO4 ^x and YBa3Cu3O6x. In these cases an insulator is converted to a p-type conductor. We tried the opposite approach, ie.e., cation intercalation to produce n-type conductors. Layered cuprates of the type A2Cu2O2 ^x and A3Cu2O4X2 (A = Ca or Sr; X - Cl, Br) were the starting points. Lithium intercalation was attempted by reaction of these materials with n-butyl lithium. Although some intercalation appeared to occur, no superconductivity was observed in the products.
