Priority Programme ,,Polymer-based Batteries" (SPP 2248);
Deutsche Forschungsgemeinschaft (DFG)
Amongst the different energy storage systems/batteries, polymer-based batteries represent an emerging technology. They feature interesting properties like lightweight, printability, flexibility as well as charging within few minutes (down to even seconds). Such polymer-based batteries can be fabricated utilising organic materials without the requirement for other critical raw materials. The well-defined structure of organic/polymer materials offers reliable structure-property relationships, and, thus, a well controllable and tuneable electrochemical behaviour can be achieved. The Priority Programme aims at the elucidation of structure-property-relationships, the design and synthesis of novel active materials, which will result in polymer-based batteries with preferably high capacities and longer lifetime over many cycles.
Therefore, the research within this Priority Programme will be divided into:
o modelling for the identification of promising materials
o understanding of the occurring (redox) processes as well as possible side reactions
o the design and synthesis of redox-active polymers
o the development of novel electrolytes
o detailed characterisation in order to shed light on the processes occurring in the composite mixtures that are used as the battery electrodes (particularly by in situ and in operando characterisation techniques)
There are three main pillars of the planned research activities: modelling, synthesis of the materials (i.e. redox-active polymers, electrolytes, carbon-rich materials) and characterisation (from the level of the materials over electrodes to full cells). Preferably, consortia of two or three principle investigators should form and cover at least two of these research fields in their joint proposal. For instance, modelling and characterisation projects should be linked to a synthetic partner. At least one half-cell of a polymer-based battery should be the central core of the corresponding projects - the study of full cells is not mandatory (the half-cells can be tested utilising metal-based electrodes, e.g., Li, Na, Zn). The participation of young research groups in the consortia is greatly encouraged.
The Priority Programme is focused on "solid" polymer-based batteries, i.e. the following topics will be excluded:
o pure optimisation studies of other (non-polymeric) electrodes (e.g., Si-anodes) in combination with "standard"/established polymer electrodes (e.g., poly(TEMPO))
o organic redox flow batteries
o polymer redox flow batteries
o polymer electrolytes for any (e.g., Li, Na or other) metal-ion batteries (without any polymer-based active materials)
For organisational purposes, all researchers that plan to submit a proposal for the first funding period are kindly asked to show their interest by sending an abstract (max. 1 A4-page) with preliminary title, short description of the planned work and rough cost estimate to DFG head office (Link auf E-Maililka.paulus@dfg.de) and the coordinator (Link auf E-Mailulrich.schubert@uni-jena.de) by 1 August 2019.
