Linivo4-Promising Thin Films For Use As Anode Mate

LiNiVO4-promising thin exposures for do as anode framework in microbatteries Authors: M.V. Reddy, C. Wannek, B. Pecquenard, P. Vinatier, A. Levasseur script of Power Sources 119-121 (2003) 101-105 This article studies the thin film deposition of lithium nickel vanadates by way of radio frequency magnetron spattering for use in the microelectronics industry. Lithium and lithium-ion batteries are popular and abundant used external power sources for all sorts of different applications, just now when the ability to integrate these types of power sources on a break off is even much attractive. However, to accommodate the constantly diminishing climb of electronics devices, physical vapor technology must be use to integrate the batteries into such small devices. This article states several prescribed attributes for lithium nickel vanadates that support its ability to be a superb anode square in micro-batteries. It was anchor that well crystallized, the materi al would make a good cathode, and while amorphous, it would make a good anode. It was discovered that the material has a very grand capacity around 1100 mAh/g at the second cycle, which is more than twice as high as graphite electrodes.

several(prenominal) experiments were performed where the splattering parameters, such as power, discharge gas, target-substratum length, and total jam were change to determine how the structure and morphology of the thin films changes and which order results in the most favorable film. The parameters that form the ideal film were found to be: power = 30 W, target to substrate distance = 8 cm, total pressure = 1 Pa and ! partial(p) pressure of oxygen = 10 mPa. The sputtering targets were do by sintering cold pressed lithium nickel vanadate demolish at 600C for 8 hours in air. The thin films were deposited on a manakin of substrates, such as disks of stainless steel, block of glazed carbon copy and aluminum foil. The substrates were ultrasonically cleaned in a pee and propanone bath before use. The authors...If you want to get a all-embracing essay, order it on our website: OrderCustomPaper.com
