Phd Thesis: Towards Solvent Free Processes: Ex-situ

hace 2 meses

VitoriaGasteiz, España CIC energiGUNE A tiempo completo

**JOB DESCRIPTION**:
CIC energiGUNE is recruiting a predoctoral researcher to work in the development of solvent free manufacturing methods for polymeric solid-state batteries. The aim of the project is to develop and validate a solventless manufacturing process for reducing the use of organic solvents, energy consumption, costs and contamination of the current Li-ion battery fabrication methods. To achieve that, this PhD thesis will be focused on manufacturing of hybrid solid-liquid electrodes which are considered the intermediate step between the current liquid electrolyte battery that contains porous electrodes and the true All Solid-State Battery.

Hybrid solid-liquid electrodes, also called gelled electrodes, are based on polymer matrices that absorb liquid electrolytes acting as the ionic conductive phase within the composite electrode. These gelled composite electrodes facilitate an intimate interface between all the components of the electrode. On the other hand, the integration of the electrolyte with the active material particles and conductive additives influence aspects related to the cell design, production and scalability. In terms of processing, many of the steps being used during conventional Li-ion battery cell production can be directly transferred to polymeric solid-state batteries; however, new techniques oriented to dry processing are needed to reach the next generation battery technology.

**Main job functions**:

- Fabrication of the viscoelastic paste and gelled electrodes by solventless processes and characterization of their key parameters.
- Tuning the manufacturing parameters for obtaining electrodes with high loading, active material contents and low porosities.
- Mechanical, microstructural and electrochemical characterization of the solventless electrodes and comparison against gelled electrodes prepared by solvent process.

**Area**: Electrochemical energy storage (EES)

**Group**:Cell Prototyping

**WHAT WE OFFER**:

- We are offering a 3-year predoctoral contract and advantageous professional development opportunities with the possibility of 1 year extension based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs.
- Flexible working hours promoting work-life balance and self-organization.
- On-site work model with the option to telework.
- Full access to cutting-edge laboratory facilities and characterization platforms.
- The incorporation to a top research center in Europe that makes high quality research and impactful contributions to the energy and sustainability fields.
- Professional and personal development: opportunity to attend seminars, international conferences, training courses, etc.
- Integrated, enthusiastic, international and multidisciplinary environment.
- A welcome program that offers help with finding accommodation and addresses other aspects to help you integrate into the local environment (such as free language courses, assistance with the administrative procedures, help with schools for children ).
