Nonaqueous battery containing sulfur dioxide. Kuo, H. C.; Bowden, W. L.; Gopikanth, M. L. (Duracell International, Inc., USA). Belg. BE 900053 A1 2 Jan 1985, 7 pp. (French). (Belgium). CODEN: BEXXAL. CLASS: ICM: H01M. APPLICATION: BE 21-249 29 Jun 1984. PRIORITY: US 83-509680 30 Jun 1983. DOCUMENT TYPE: Patent CA Section: 72 (Electrochemistry) A nonaq. rechargeable battery is described, comprising an anode of an alkali metal (e.g. Li) or an alk. earth metal and an inorg. electrolyte consisting of SO2 with a salt of the electrolyte (e.g. LiAlCl4 or LiGaCl4) which is dissolved. The cathode is made of Mo chloride (MoCl3 [13478-18-7] or MoCl4 [13320-71-3]) which is insol. in SO2 and represents a cathode-active material for increasing the battery capacity. In an example, a button-type battery is fabricated by using 20 g of an electrolyte of LiAlCl4.3SO2, 2 Li electrodes (each of which has a support a Cu sheet, 2.5 ′ 4.1 ′ 0.05 cm). The cathode consists of 1.8 g of MoCl3 80, C black 12, and PTFE 8 g on a Ni grid (2.5 ′ 4.1 ′ 0.12 cm) and is sepd. from the Li electrodes (between which it is placed) by nonwoven glass separators. The battery is discharged at 20 mA and has a capacity of 420 mA-h up to a cutoff potential of 1 V and a vacuum potential of 3.1 V. The obtained capacity is ~219% of the theor. capacity of MoCl3.

DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Me methacrylate (I) and styrene (II) were grafted with good graft efficiency onto a bis(4-hydroxyphenyl)sulfoxide-2,2-bis(4-hydroxyphenyl)-1,1,1-trichloroet hane-succinic acid polyester (III) in 2 steps in the presence of MoCl3 and Cr(OAc)2 [628-52-4]-morpholinocyclohexene [66573-99-7] catalysts. MoCl3 was oxidized to MeOCl3 by S(O) groups during I-III graft polymn. and Cr(OAc)2 reacted with CCl3 groups during II grafting onto I-III polymers. Grafting I onto III increased with increasing MoCl3 concn. and with decreasing III concn. .
