Abstract
The influence of nonuniformity properties of the LiCoO2 cathode film deposited by magnetron sputtering on the capacity of all-solid-state thin-film lithium-ion batteries (ASSLIB) was studied. It was found that the film nonuniformity corresponds to the magnetron plasma density distribution and the angular distribution of sputtered particles. The capacity distribution of the ASSLIB with LiCoO2 cathode depending on the distance to the substrate center was studied. The maximum capacity corresponded to the dense part of the toroidal region of the magnetron plasma. It was determined that the main causes of batteries capacity decline in the central part and on the edge of the substrate are the impurity phase of lithium cobaltate and the smaller thickness of the cathode layer, respectively.
期刊介绍：
Russian Microelectronics covers physical, technological, and some VLSI and ULSI circuit-technical aspects of microelectronics and nanoelectronics; it informs the reader of new trends in submicron optical, x-ray, electron, and ion-beam lithography technology; dry processing techniques, etching, doping; and deposition and planarization technology. Significant space is devoted to problems arising in the application of proton, electron, and ion beams, plasma, etc. Consideration is given to new equipment, including cluster tools and control in situ and submicron CMOS, bipolar, and BICMOS technologies. The journal publishes papers addressing problems of molecular beam epitaxy and related processes; heterojunction devices and integrated circuits; the technology and devices of nanoelectronics; and the fabrication of nanometer scale devices, including new device structures, quantum-effect devices, and superconducting devices. The reader will find papers containing news of the diagnostics of surfaces and microelectronic structures, the modeling of technological processes and devices in micro- and nanoelectronics, including nanotransistors, and solid state qubits.
