Linivo4-Promising Thin Films For Use As Anode Mate

LiNiVO4-promising thin exposures for riding habit as anode framework in microbatteries Authors: M.V. Reddy, C. Wannek, B. Pecquenard, P. Vinatier, A. Levasseur playscript of Power Sources 119-121 (2003) 101-105 This article studies the thin film deposition of atomic number 3 nickel vanadates by way of radio frequency magnetron cough up for use in the microelectronics industry. Lithium and lithium-ion batteries are popular and extensive used external power sources for all sorts of different applications, lone(prenominal) when the ability to integrate these types of power sources on a break away is even more attractive. However, to accommodate the constantly diminishing prove of electronics devices, physical vapor technology must be use to integrate the batteries into such small devices. This article states several ordained attributes for lithium nickel vanadates that support its ability to be a superb anode secular in micro-batteries. It was effectuate t hat well crystallized, 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 royal 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 sputtering parameters, such as power, discharge gas, target-substratum aloofness, 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 uncomplete 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 physical body of substrates, such as disks of stainless steel, block of glazed nose candy and aluminum foil. The substrates were ultrasonically cleaned in a pee and dimethyl ketone bath before use. The authors...If you want to get a good essay, order it on our website: OrderCustomPaper.com
