Aiming to close the gap with future ASSB chemistries, Solvay has developed a
specific fluorinated polymer based on PVDF and a designed chemistry allowing
the formation of in-situ cross-linked network. This innovation led to the
development of a quasi-solid state batteries, where electrolyte is trapped in
a complex hybrid network bringing advantages in processing, cost, performances
and safety. CEA has a sound experience in the system, being a partner of
Solvay in this technology for several years. This allowed to developed
innovative processes ending in manufacturing cells of several hundred
milliampere hours working for hundreds of cycles. Together the two partners
have gathered their efforts resulting in more than ten patents around the
The research project will be articulated on the understanding of interfacial
and transport properties of the hybrid polymeric system. It will primarily
focus on the impact of the various manufacturing steps on the properties of
the active materials involved in the systems and on the impact of network
features on attributes in conductivity, safety and mechanical properties:
- The optimization of electrochemical formation of the cell and its links
with the native surfaces of the various active material will also be an
important part of the work.
- This optimization will be paired with an important work devoted to surface
characterization like XPS, high resolution microscopy and electrochemical AFM.
- Interfaces at various scale, between the electrolyte and active materials
as well as between the layers, will constitute a major point of investigation.
Advanced impedance technics, cycling protocols and coupling electrochemical
tests with structural and microstructural analytical tools.
- In addition, taking benefits from previous developments, in operando
technics such as tomography could be implemented to gain a better
understanding of the interplay between electrodes features at mesoscale and
transport properties at various C-rates.
- Implementation of innovative technics and cell geometry is also expected in
order to probe the in-operando behaviour of such system.
Major part of the work will be done at CEA Liten (Grenoble) with frequent
secondments at Solvay facilities in Paris and Bruxelles. Secondments in large
scale instruments is envisioned as well as secondment to build theoretical
framework to support the analytical work.
The beginning of the thesis is planned on January, 1st 2023 at the latest and
for a duration of 3 years.
This topic is part of the European project DESTINY, Doctorate programme on
Emerging battery Storage Technologies INspiring Young scientists
(https: // www. destiny-phd.eu/), which aims at creating a new paradigm change
in battery research. CNRS, acting as the coordinator, with 42 European partner
institutions working on future batteries and related issues on energy storage,
committed to ambitiously participate in the long-term research initiative
Battery 2030+. The project consists in delivering a competitive edge to
European industry and academy within the rapidly emerging green technology
areas of Electro-mobility and Large-scale energy storage.
