Replacing the liq. electrolyte in lithium batteries by a solid has been a long-standing goal of the battery industry due to the promise of better safety and the potential to produce batteries with higher energy densities. Recently, sym. polystyrene-block-p ...
A perylene sensitizer, ID176, was recently reported which performs much better in solid state dye-sensitized solar cells than in those using liq. electrolytes with iodide/tri-iodide as the redox couple. Here, a characterization is presented of the sensitiz ...
This work describes different strategies for the detection of biologically relevant analytes. The main goal was to achieve sensing in water, which is a prerequisite for application to real biological samples. In several cases, we could demonstrate that our ...
Reversible chemical delithiation/lithiation of LiFePO4 was successfully demonstrated using ferrocene derivatives, based on which a novel energy storage system - the redox flow lithium-ion battery (RFLB), was devised by integrating the operation flexibility ...
The performance enhancement of dye-sensitized solar cells (DSCs) in lithium-free and lithium-containing electrolytes under visible light-soaking was examined by impedance spectroscopy and photovoltage transient decay measurements. The improvement was found ...
Over the past decades, there have been many projections on the future depletion of the fossil fuel reserves on earth as well as the rapid increase in green-house gas emissions. There is clearly an urgent need for the development of renewable energy technol ...
Efficiency and energy consumption reduction are becoming a key issue in elevation applications. Energy Storage Systems (ESS) can play a significant role on this field, together with their associated Energy Management System (EMS) in order to optimize the o ...
Self-assembled monolayers (SAMs) of redox-active molecules on mesoscopic substrates exhibit two-dimensional conductivity if their surface coverage exceeds the percolation threshold. Here, we show for the first time that such molecular charge transport laye ...
Supercapacitors are components for energy storage, well dedicated for applications where energy storage can help to the smoothing of strong and short time power solicitations of a distribution network. Those properties are developed for two examples. The f ...
An energy storage system based on battery and supercapacitors is presented. It allows bigger amount of intantaneous power. The properties of the proposed system are oriented in high efficiency, in a special topology with parallel channels. The paper presen ...
