Using a solid-state reaction strategy, nominal Li3TiO3F oxyfluorides ceramics were fabricated, and its sintering behavior, microstructure, phase assemblages, as well microwave dielectric performances all investigated. The main of with cubic structures accompanied small amounts the LiF or Li2TiO3 secondary was identified by XRD analysis. SEM analysis showed that uniform dense microstructure obta...

Full concentration gradient lithium-rich layered oxides are catching lots of interest as the next generation cathode for lithium-ion batteries due to their high discharge voltage, reduced voltage decay and enhanced rate performance, whereas lithium residues on its surface impairs structure stability long-term cycle performance. Herein, a facile multifunctional modification method is implemented...

First-principles simulations of the porous layered calcogenide materials Li2SnO3 and Li2SnS3 are used to study their structures, Li ion mobilities, and their interactions with excess Li. The pristine materials are characterized by a regular pattern of voids within the calcogenide layers which are occupied by intralayer Li ions. The energetically most favorable Li ion migration processes for bot...

This paper analyzes part of the reactor experiments on study tritium and helium release from promising two-phase lithium ceramic (Li2TiO3 Li4SiO4) natural enrichment conducted by vacuum extraction. The basis for such an analysis was a more careful time trend pressure changes gases in chamber with test samples. In particular case, it clearly shown that fluctuations observed during irradiation ma...

Solid tritium breeding materials are expected to be used in high-temperature conditions for a long time fusion DEMO reactor. Thus, it is important understand how bred releases from the long-term heated material under environment as close condition possible establish fuel cycle and keep safe. In this work, release behavior irradiated Li2TiO3 pebbles that was preheated 720 h at most observed by h...

The aim of this work was to study resistance helium accumulation processes in the structure surface layer lithium-containing ceramics and subsequent destruction embrittlement processes, depending on radiation fluence. objects were Li2TiO3-type obtained by thermal sintering. fluence dependency changes structural strength properties determined be range from 1018 1022 ion/m2, which corresponded co...

Li ion conducting Li3PO4 thin film electrolytes with thickness 300nm, 650nm and 1.2μm were deposited on Al2O3 substrate at room temperature by thermal evaporation method. Reference and sensing electrodes were printed on Au interfaces by conventional screen printing technique. The overall dimension of the sensor was 3 x 3 mm and of electrodes were 1 x 1.5 mm each. The fabricated solid state pote...
