Linivo4-Promising Thin Films For Use As Anode Mate

LiNiVO4-promising thin exposures for hire as anode framework in microbatteries Authors: M.V. Reddy, C. Wannek, B. Pecquenard, P. Vinatier, A. Levasseur account book 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 peel for use in the microelectronics industry. Lithium and lithium-ion batteries are popular and unsubtle used external power sources for all sorts of different applications, exactly when the ability to integrate these types of power sources on a break off is even more(prenominal) attractive. However, to accommodate the constantly diminishing control surface of electronics devices, physical vapor technology must be use to integrate the batteries into such small devices. This article states several institute attributes for lithium nickel vanadates that support its ability to be a superb anode sensible in micro-batteries. It was set up that well c rystallized, the material would make a good cathode, and while amorphous, it would make a good anode. It was discovered that the material has a very soaring 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 spatter parameters, such as power, discharge gas, target-substratum blank, and total jam were varied 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 overtone 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 frame of substrates, such as disks of stainless steel, block of glazed coulomb and aluminum foil. The substrates were ultrasonically cleaned in a pee and acetone bath before use. The authors...If you want to get a adequate essay, order it on our website: OrderCustomPaper.com
