Вплив лазерного опромінення на електрохімічні властивості композиту MoS2/С

The paper presents the results of studies of electrochemical properties of composite MoS2/C. It is shown that the contribution to the conductivity of composites makes a charge accumulation capacitive nature inherent in high-conductive carbon, which is situated between the layers of MoS2, improved charge transfer processes during charge / discharge, and quick turnaround faradeyivski processes inherent molybdenum disulphide. Found that the highest discharge specific capacity has laser irradiated composite MoS2/C with a carbon content of 70% (209 F/g), due to the best combination of two mechanisms of charge accumulation and activation of charge carriers under the influence of laser.У роботі представлено результати досліджень електрохімічних властивостей композиту MoS2/C. Показано, що вклад у провідність композитів вносить як ємнісний характер накопичення заряду, притаманний  високопровідному вуглецю, який, розташовуючись між шарами MoS2, покращує перенесення заряду під час процесів заряд/розряду, так і швидкі оборотні фарадеївські процеси, властиві дисульфіду молібдену. Виявлено, що найвищою розрядною питомою ємністю володіє лазерно опромінений композит MoS2/С з вмістом вуглецю 70 % (209 Ф/г), що пов’язано з найкращим поєднанням двох механізмів накопичення заряду та зростанням дефектності структури і активацією носіїв заряду під впливом лазера

The Composite Nickel Hydroxide / Activated Carbon as Electrode Material in the Battery Storage Devices

The paper presents theresults of studies of the structure and electrochemical properties of composite β-Ni(OH)2/C. It is shown that the diffractograms composites intered β-Ni(OH)2/C in addition tope aks characteristic NiO,there is a broad diffraction peak at23°, which can be attributed to the activated carbon. Found that the composite electrode based onβ-Ni(OH)2/C has a specific capacity, which is almost 25 times higher than the capacity for the output of nickel hydroxide at a current of 1m A. Keywords: nickel hydroxide, activated carbon,thermogravimetry, X-ray analysis, galvanostatic and potentsio-dynamic methods, the accumulation of charge.</p
