The polyanion cathodes for Li-ion batteries, namely LiFePO4, Li2FeP2O7 and Li2FeSiO4, were synthesized by very short high-temperature treatment (approximately several minutes) subsequent quenching. Methylcellulose—a polymer with thermally driven water solubility—was used as the medium in which precursor solutions dispersed prior to high temperature treatment. methylcellulose pyrolytically decom...

The generation, storage and use of electric energy is a relevant issue for the modern society that dependent from this typology its activities (e.g. heating, goods production). Batteries are key components energy, to be used large set domestic, industrial transport applications. paper investigates environmental impacts two different battery technologies as accumulator in context production plan...

Significant research efforts are being made to understand, and ultimately mitigate, the degradation of Li-ion batteries upon usage. Currently, battery ageing models are used in order to optimise the battery usage and to achieve robust battery solutions. The purpose with this work is to obtain deeper understanding of the ageing factors for high-power graphite || LiFePO4 cells and to develop a se...

The new instrument based on the dispersive optics for the X-ray absorption fine structure (XAFS) was developed at BL-5 of the SR Center. The vertical axis of the synchrotron radiation is used to disperse the X-ray energy in the newly developed instrument, named vertically dispersive XAFS (VDXAFS) instrument. The vertical energy dispersion is achieved using a cylindrical polychromator, and the h...

An abundant hollow nanostructure is crucial for fast Li+ and K+ diffusion paths sufficient electrolyte penetration, which creates a highly conductive network ionic electronic transport. In this study, we successfully developed molecular-bridge-linked, organic–inorganic hybrid interface that enables the preparation of in situ nitrogen-doped carbon nanospheres. Moreover, prepared HCNSs, with high...
