iHUB Poly 9



In the near future, an increasing share of our portable energy needs will be based on mobile energy storage devices, such as lithium-ion or lithium-sulfur batteries.

As part of a concerted effort to become a leader in the development and supply of advanced materials for such sustainable energy applications, Arkema France and CP2M, a CNRS / CPE / Univ. Lyon 1 research laboratory on the Lyon Tech-La Doua Campus, created this joint laboratory entitled Innovation Hub, Polyemr 9 (iHub Poly-9). Research focuses primarily on the development of fluoropolymers for battery and other advanced applications.

The joint expertise of the CP2M and Arkema in polymerization chemistry, particle stabilization, particle structure and process engineering will provide material solutions for the batteries of the future.  A long history of collaborative research with two local partners (the CP2M and Arkema's Pierre Bénite facility are less than 20 km apart).  In addition to a shared interest in the fundamentals of polymerisation between the 2 partners, the CP2M lab is one of the only academic laboratories in the world with the infrstructure and technical know-how needed to support such a wide range of activities for waterborne VF2 polymerisation research.

This important new project has been established to reinforce a history of successful research collaborations reaching back over 3 decades, and covering a wide range of topics from polymerization kinetics to particle stability, and from high solid content latexes to on-line monitoring and control.  More recently, Arkema and the CP2M polymer team have teamed up on several different research projects related to the production of poly vinylidene fluoride (PVDF):  

  • ANR PRCE Scale-up, dealing with the scale of the emulsion polymerization of vinylidene fluoride.  This project included a primarily experimental PhD project in which we investigated the kinetics of the polymerization process, and the impact of mixing on the apparent polymerization rate.  This was accompanied by CFD simulations to better apprehend mixing times as a function of reactor scale.  A 4 litre pilot plant was built at the CP2M for this purpose, and allowed us to run polymerisations at pressures of over 80 bars.
  • This was shortly followed by a CIFRE in which we explored the production of PVDF latexes in surfactant free systems using RAFT and the concept of polymerisation induced self assembly (PISA).
  • A second ANR PRCE called CLEANPOLY, also with the participation of KEM ONE.  This project deals with the study of particle stability and reactor fouling in PVDF and PVC dispersed phase polymerisations.
  • In 2020 we were awarded a Pack Ambition Recherchesponsored by the Auvergne-Rhône Alps Regionaly government. This product will pick up where Scale-up left off, and focus on quantifying the impact of porcess related parameters such as the stirring of the reactor in VDF polymerisation.

The iHub Poly-9 project represents a budget of more than 3 millions euros over the course of 5 years in its first phase.  It will inlcude 3 CIFRE PhD projects, a PhD from the IFLEM Regional project, an Arkema Engineering working full time at the CP2M laboratory, 3 Arkema Engineerings, 3 full time researchers from the CP2M, as well as important contributions from the CP2M technical staff.

Shared resources also include a dedicated polymer synthesis laboratory at the CP2M, including 2 pilot reactors of 4L for process engineering studies and scale-up studies, as well as 2 smaller reactors of 350 ml for the exploration of new synthetic pathways.
