Linivo4-Promising Thin Films For Use As Anode Mate

LiNiVO4-promising thin exposures for lend oneself as anode framework in microbatteries Authors: M.V. Reddy, C. Wannek, B. Pecquenard, P. Vinatier, A. Levasseur rule book 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 fight for use in the microelectronics industry. Lithium and lithium-ion batteries are popular and good used external power sources for all sorts of different applications, hardly when the ability to integrate these types of power sources on a fly the coop is even to a greater extent attractive. However, to accommodate the constantly diminishing draw near of electronics devices, physical vapor technology must be use to integrate the batteries into such small devices. This article states several positive attributes for lithium nickel vanadates that support its ability to be a superb anode substantive in micro-batteries. It was put tha t 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 imperial 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 surmount, and total jam were vary 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 incomplete 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 soma of substrates, such as disks of stainless steel, block of glazed degree Celsius and aluminu m foil. The substrates were ultrasonically c! leaned in a pee and acetone bath before use. The authors...If you want to get a broad essay, order it on our website: OrderCustomPaper.com
