A new compound has been synthesized, Bi16Sr28Cu,7069+6; it crystallizes in a monoclinic cell with a = 48.40 (1) A, b = 5.495 (1) A, c = 16.283 (4) A, and p = 109.96 (2)o. This phase exhibits 2212 ribbons running along c that are 9 Bi atoms wide, and shifted by 5.3 A with respect to each other; these ribbons are interconnected through thin layers involving CuOs octahedra. In spite of its close relations with an ideal (101)~shear "2212" structure, this cuprate cannot be considered as such and is termed (lOl)-collapsed "2212" cuprate in agreement with previous works on (OlO)-collapsed "2201" cuprates. The rupture of the [CuOZ], layers and the possibility of using these phenomena for creating columnar defects in high-Z', superconducting cuprates are also discussed. o wz Academic PRSS, IX.

The crystal structure of the sample was analyzed by means X-ray diffraction (XRD), and scanning electron microscopy (SEM). The molar ratio Li/Ti has been varied for simulated the litigation processes in anode materials for lithium battery, and the interesting product with relation Li:Ti 5:5 has been obtained, with major crystalline structure. The atrane route is one of the most appropriate synthesis methods for obtain this anodic material.

The thermal treatment favors the pyrolysis. The products obtained are compared against the commercial solid-solid method. They have a high crystallinity degree and particle micrometric order; in minor size that in solid state reaction. Both materials synthesized show high potential for their application as cathode in Lithium Ion Batteries. ‡ Original Spanish title: Nueva ruta pirolítico/atrano para la síntesis de electrodos catódicos LiCoO2 y LiMn2O4
