PROJECT DESCRIPTION:

Rechargeable batteries are the key to transitioning away from fossil fuel dependence. Current Li-ion batteries use carbonate-based liquid electrolytes which are flammable and can leak (making them inherently unsafe). On this regard, solid polymer electrolytes (SPEs), which comprise a lithium salt and an elastic polymer matrix, have been investigated as important candidates for enhancing the energy density and safety of the next-generation rechargeable lithium metal batteries (LMBs), due to their good flexibility, no-leakage, less-flammability, light weight, and good compatibility with Li metal. However, before we can see the full potential of SPEs, important fundamental limitations must first be addressed, such as the low ionic conductivity, lithium dendritic growth, polarization of the battery during operation at high currents related to low transport number, and overall short battery life. Thus, the search of new polymer and lithium salt chemistries raises as a promising strategy to solve aforementioned issues.

CIC energiGUNE is seeking an experienced Researcher to engage in the research and development of new electrolytes with a wide experience in the field of organic synthesis.

JOB FUNCTIONS:

  • Synthesis and characterization of polymer electrolytes, organic plasticizers, lithium salts, and related materials.
  • Characterize the materials using analytical instruments.
  • Proof of concept study of polymer-based solid batteries at the lab level.
  • Collaborate in writing proposals to secure funding from government and industrial sources.

TECHNIQUES TO BE USED:

  • Standard operating procedures for organic and polymer synthesis.
  • Structural and physico-chemical characterization: nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FTIR), Raman, ICP, X-ray diffraction, elemental analysis, gel permeation chromatography (GPC), mass spectroscopy (MS), differential scanning calorimetry (DSC), thermogravimetric analysis, scanning electron microscopy (SEM).
  • Electrolyte preparation, cell integration, and component characterization.
  • Electrochemical testing.
