Energy demand is still mainly satisfied by the direct but inefficient and polluting conversion of chemical energy of fossil fuels because of the lack of highly performing energy storage systems. Electrochemical power sources differ from others due to the fact that the energy conversion occurs from chemical into electrical without any intermediate step, resulting in higher energy efficiencies in addition to a much lower environmental impact due to the absence of any gaseous emission. Among the various choices, electrochemical devices, such as batteries, supercapacitors, and fuel cells, are one of the most, if not the most, suitable answers for efficient energy storage and conversion.
Electrode chemistry and formulation play a key role in the performance and safety of electrochemical devices. For instance, electrodes, in addition to electrochemical active species, have to contain passive components (electronic and/or ionic conductor, binder, etc.), which, even if not affecting the energy density, strongly influence the power density, cycling behavior, and reliability of the device. Therefore, although well-known over time, these issues are currently under deep investigation worldwide.
This Special Issue will offer an appealing forum to bring together the latest results obtained by key laboratories presently involved in R and D of composite electrodes for batteries, supercapacitors, and fuel cells. Again, this Special Issue represents an optimal site for welcoming the latest innovations and, accordingly, authors from top laboratories are invited to submit their forthcoming results.

Title: LFP-based gravure printed cathode for lithium-ion printed batteries
Author: M. Montanino
The printed batteries are more and more investigated since they are necessary to supply small electronic devices of growing daily use. In this frame the most industrially diffused gravure printing appears as the best method since its capability to couple high speed and high definition and to produce any kind of shape.
Nowadays such technique is one of the most appealing for the production of functional layers for electronics but is very few investigated for this scope. Here we propose a LFP-based gravure printed cathode for lithium-ion rechargeable printed batteries demonstrating the possibility to use such technique for this propose.
Title: Composite electrospun membranes with ZnO nanoparticles for batteries applications
Author: Antonio Rinaldi et. al.
Electrospinng is an innovative and scalable manufacturing technology to produce complex non-woven membranes made of fibers with a diameter distribution from a few nanometers up to several micrometres, with a largely tunable mesoscale arrangement of the fibers. Although no mainstream industrial deployment has emerged yet, electropun membranes have already began to be explored for Lithium based battery applications, both for the electrode and separator compartments, in the former case being typically necessary to perform single or multistep pyrolysis treatments to yield microstructured carbon electrode. In any case, the transport properties and performance of such membranes highly depend on microstructural details (e.g. fiber distribution, architecture, porosity fraction and distribution, etc.), which can be tuned by controlling the native polymer and the process parameters. In addition, in this study we demonstrate the possibility to obtain a tailorable composite microstructure by adding small percentages (from 0.5% up to 5%) of non-percolating nanometric ZnO dispersoids in a polymeric fiber matrix. Polycaprolactone (PCL) was selected for convenience in our moke-up system. The results indicate a fiber diameter reduction trend with a minimum at around 2% of ZnO. The microstructural parameters of such composite hybrid membranes are correlated to electrical performance. Implications on battery performance are discussed.
