چکیده
Laboratory research into bulk-type solid-state batteries (SSBs) has been focused predominantly on powder-based, pelletized cells and sufficient to evaluate fundamental limitations tailor the constituents some degree. However, improve experimental reliability for commercial implementation of this technology, competitive slurry-cast electrodes are required. Here, we report application an approach guided by design experiments (DoE) influence type/content polymer binder conductive carbon additive cyclability processability Li1+x(Ni0.6Co0.2Mn0.2)1?xO2 (NCM622) cathodes in SSB using lithium thiophosphate solid electrolytes. The predictions verified charge-discharge impedance spectroscopy measurements. Furthermore, structural changes gas evolution monitored via X-ray diffraction differential electrochemical mass spectrometry, respectively, attempt rationalize support DoE results. In summary, optimized combination leads high performance good processability.

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Effective management of passive layers using composite cathodes in solid state magnesium batteries.
A simple and effective method for the management of the passive layer in solid state batteries is reported. The success is achieved using a composite cathode with embedded channels of polyaniline allowing smooth charge transfer across the passive layer. The composite cathode manifested better performance in terms of the cell characteristics and shelf life.
