Secondary lithium-ion nonaqueous-electrolyte battery and lithium-insertion cathode material for this battery. Mayer, Steven T. (Polystor Corporation, USA). PCT Int. Appl. WO 9701191 A2 9 Jan 1997, 30 pp. DESIGNATED STATES: W: CA, CN, KR; RW: AT, BE, CH, DE, DK, ES, FI, FR, GB, GR, IE, IT, LU, MC, NL, PT, SE. (English). (World Intellectual Property Organization). CODEN: PIXXD2. CLASS: ICM: H01M. APPLICATION: WO 1996-US10760 21 Jun 1996. PRIORITY: US 1995-493715 22 Jun 1995. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) The material comprises a mixt. of a 1st homogeneous Li- and transition metal-contg. material and a 2nd homogeneous Li- and transition metal-contg. material, and binders as necessary. By choosing particular types and relative amts. of the 1st and 2nd homogeneous cathode materials, the resulting composite cathodes can have matched formation and reversible cycling capacities (for a given anode material) and sloping discharge profiles. The 1st and 2nd homogeneous cathode materials used in the composite cathodes may each be 1 of Li Mo sulfides, Li Mo oxides, Li V oxides, Li Cr oxides, Li Ti oxides, Li W oxides, Li Co oxides, Li Ni oxides, and Li Mn oxides. The Li-ion batteries include a container, a nonaq. electrolyte, and an anode including a mixt. of homogeneous graphitic and homogeneous nongraphitic C particles.Except for chemicals metioned above, 12057-17-9 and 12031-65-1 are also used. .

Study on electrochemical performance of LiMn2O4-based cathode materials at elevated temperature. Li, Zhimin; Qiu, Weihua; Cao, Quanxi; Zhang, Hua (School of Technical Physics, Xidian University, Xi'an 710071, Peop. Rep. China). Guisuanyan Xuebao, 32(1), 10-14 (Chinese) 2004 Guisuanyan Xuebao Bianjishi. CODEN: KSYHA5. ISSN: 0454-5648. DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) LiMn2O4 and LiAl0.1Mn1.9O3.9F0.1 cathode materials were synthesized by solid-state reaction and tested by x-ray diffraction and SEM. High-temp. electrochem. performances of the materials were investigated. The results show that LiAl0.1Mn1.9O3.9F0. 605685-97-0 and 12057-17-9 are also in the experiment.1 with Al3+ and F-1 dopants exhibits good spinel structure and morphol. Compared to LiMn2O4, LiAl0.1Mn1.9O3.9F0.1 has discharge capacity of 110 mA-h/g and capacity retention of 96% after 15 cycles at 55°, and shows good electrochem. properties (detd. from impedance spectra). .
