Relevance of the project

In recent years, flexible and safe LIBs have become a field of intensive research as a promising power source for forthcoming flexible and wearable electronics. Despite the fact that there are many works on solid-state batteries in literature, the practical application of them is still hindered. There is a necessity for the development of flexible all-solid-state batteries with high performance flexible electrodes which are combined with solvent-free electrolytes. In this project, a number of alternative materials have been proposed with the main focus on applicability in flexible lithium-ion batteries (LIBs). Flexible nanofibrous electrodes, mechanically durable solid/gel polymer electrolytes are aimed to develop by using several techniques such as electrospinning, UV-photopolymerization and UV-crosslinking. 

The project goal

The project goal is the development of flexible components namely nanofibrous electrodes and solid/gel polymer electrolytes for solid-state Li-ion batteries to power flexible and wearable electronics. The project aims to obtain mechanically durable polymer electrolytes with improved ionic conductivity at ambient temperature and combine with a porous electrode.

Expected Results

1) Innovative and high-performance flexible electrodes and ion conductive polymer electrolytes for all solid-state lithium-ion batteries will be developed and investigated. Freestanding, transparent SPEs with improved ionic conductivity (~10-6 S cm-1), at lower temperatures compared to conventional PEO based SPEs (10-8, ~10-7 S cm-1) will be developed and optimal conditions will be established. Nanostructured flexible components with good mechanical and electrochemical stability will be achieved.

2) The research results on material synthesis and characterization, performance will be published in leading international peer-reviewed journals of editorial offices such as Elsevier, International Electrochem. Society.

- at least two articles or reviews in peer-reviewed scientific publications on the scientific direction of the project, included in 1 (first), 2 (second) or 3 (third) quartiles in the Web of Science database and (or) having a percentile by CiteScore in the Scopus database of at least 50 (fifty);

- also at least 1 (one) article in a peer-reviewed foreign and (or) domestic publication with a non-zero impact factor (recommended by CCSES);

Also, the results will be presented at international conferences.

3) The flexible and wearable devices are expected to be the next stage of technological progress, which eventually require high capacity and flexible batteries as an energy source. Therefore, the development of advanced battery materials will lead to high-tech development through the use of innovative, safe and reliable energy storage systems. The project results will establish economically useful technologies, and new industries, efficient and ecological use of natural resources of Kazakhstan. This project will prevent the infiltration of unsafe, low quality and expensive batteries into the Kazakhstan market by enabling local production of safer and advanced batteries. High energy density and flexibility of proposed novel batteries will provide safe and reliable batteries for multifarious applications from small electronics for medical and other applications to space use, enhancing the energy independence and flexibility of our society.

4) Establishment of international collaboration with the partners will bring novel expertise to Kazakhstan both in the science and education of young specialists.

5) The potential users of the project results will be the producers of high-tech electronics, smart devises etc.

Achieved results

As a result of the project work, the following results were obtained: nanosized LiFePO4 powders were obtained by electrospinning and graphite powders by grinding using a ball mill; series of flexible films of solid polymer electrolyte with a-PDMS have been successfully obtained and investigated by UV-crosslinking method; also, a crosslinked nanofibers from modified lignin for a gel polymer electrolyte were obtained by UV-electrospinning technique; a gas system for the detection of toxic substances in battery cells during the thermal runaway of lithium-ion batteries based on Arduino has been pre-designed and studied.

Collaborative research work is going on with Marmara University (Istanbul, Turkey) and Gazi University (Ankara, Turkey).

According to the results, 1 original paper and 1 review paper were published in scientific peer-reviewed journals (Q1), indexed in the Web of Science and Scopus databases with a non-zero impact factor.
