Development of Silicon Polymer Electrodes with a Hybrid Polymer Electrolyte for All-Solid-State Lithium-Ion Batteries

PDF — 2.23 MB — 30 May 2023

The development of solid-state lithium-ion batteries is a promising step to meet the increasing demand for safe batteries with a high energy density. In this work, silicon electrodes containing an organic/inorganic hybrid polymer electrolyte (HPE) are reported. Depending on the conducting salt and the inclusion of an ionic liquid (IL), the HPE exhibits an ionic conductivity between 0.24 ± 0.11 mS cm−1 and 0.94 ± 0.07 mS cm−1 at 60 °C. The achievable capacity in Si/HPE/Li cells depends strongly on the Crate and the areal capacity of the electrodes, as well as on the electrolyte and electrode composition. Among the cells tested, those with an HPE containing lithium bis(fluorosulfonyl)imide (LiFSI) and no IL exhibit the highest capacity retention and average coulombic efficiency. The use of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and/or the addition of an IL enables higher electrode loadings, however at the expense of capacity retention. Si electrodes with a higher Si content show an improved cell performance compared to those with less Si. A combination of electrodes containing 75 wt% silicon with an HPE with LiFSI and IL reaches a high capacity of approx. 1500 mA h gSi −1 at 0.1 C with a capacity retention of 74% after 100 cycles.


Fabrication of modern lithium ion batteries by 3D inkjet printing: opportunities and challenges

PDF — 1.81 MB — 10 Jan 2023

Inkjet printing (IJP) is a prospective additive manufacturing technology that enables the rapid and precise deposition of thin films or patterns. It offers numerous advantages over other thin-film manufacturing processes, including cost-effectiveness, ease of use, reduced waste material, and scalability. The key advantage of this technique is the ability of the fabrication of complex patterns with very high precision. The IJP gives the possibility of building three-dimensional (3D) structures on the microscale, which is beneficial for modern Li-Ion batteries (LIBs) and All-Solid-State Li-Ion Batteries (ASSLIBs). In contrast to typical laminated composite electrodes manufactured by tape casting and calendaring, 3D electrode design allows the electrolyte to penetrate through the electrode volume, increasing the surface-to-volume ratio and reducing ion diffusion paths. Thus, 3D electrodes/electrolyte structures are one of the most promising strategies for producing next-generation lithium-ion batteries with enhanced electrochemical performance. Although in the literature review, the IJP is frequently reported as a future perspective for the fabrication of 3D electrodes/electrolytes structures for LIBs, only a few works focus on this subject. In this review, we summarize the previous studies devoted to the topic and discuss different bottlenecks and challenges limiting further development.



D8.11 – First report on Communication and Dissemination activities and update of the Communication and dissemination plan

PDF — 1.90 MB — 12 Nov 2021

This document describes the communication and dissemination strategy developed for the ASTRABAT project. It is the first update of the version created in M4 (D8.1). The document outlines the key elements of the communication and dissemination strategy, which include: the targeted audiences (WHO), the key messages to address them (WHAT), the tools and channels employed (HOW), the timing of the planned activities (WHEN) and the geographical level (local, European) (WHERE), hence providing a guide for the project and partners dissemination activities. The document also reports on the communication and dissemination activities performed so far by the ASTRABAT consortium. The document also describes the approach adopted to monitor the diffusion of ASTRABAT contents and quantitatively assess the impacts generated by the project communication and dissemination campaigns. The ASTRABAT Communication and Dissemination plan is a living document. The plan will be updated in M30 (D8.12). This will enable tunings of the overall communication and dissemination strategy based on the project developments and needs. The final version of the document will be released at the end of the project, with the final report on the project communication and dissemination activities (D8.13).
