Rechargeable solid-state lithium ion batteries (SSLB) require fast conducting solid electrolytes (SEs) to enable high charge and discharge rates. Li7P3S11 is a particularly promising electrolyte, exhibiting very room temperature conductivities of up 17 mS·cm–1 ductility, allowing transport through the bulk intimate contact surface electrodes. Here we present novel hot-press setup that facilitates synthesis by combining in situ electrochemical impedance spectroscopy (EIS) with simultaneous...
The localization of sensor nodes is a significant issue in wireless networks (WSNs) because many applications cannot provide services without geolocation data, especially during disaster management.
