Introduction

  • Batteries store chemical energy that can be (reversibly) converted into electrical energy by drawing a current or applying a potential
  • The energy density of batteries is determined by the specific capacity and the potentials of the electrode active materials, e.g., graphite or LiCoO2
  • Fuel cells convert chemical energy of continuously supplied fuels (e.g., methanol or hydrogen) into electrical energy with the aid of oxidants (e.g., oxygen, air)
  • There exist several types of fuel cells that either differ in regard to their oxidant (e.g. direct methanol fuel cell, DMFC) or electrolyte (e.g., proton exchange, fuel cells, solid oxide fuel cells or alkaline fuel cells)
  • Electrolyzers convert electrical energy into chemical energy by using a current to drive a non-spontaenous chemcal reaction, e.g. generating H2 and O2 from water
  • Combined with renewable energy sources, such as wind energy, electrolysis has the potential to convert excess energy into chemical energy carriers, e.g. H2 or methane

Our activities

  • Research focus on Li-ion and post-Li-ion battery technologies (e.g., lithium-sulfur)
  • Preparation and characterization of electrode materials, e.g., silicon and Li[NixCoyMnz]O2
  • Assembly of battery test cells, e.g., coin cells and pouch-cells
  • Investigation of aging mechanisms through combined electrochemical and spectroscopic measurements, e.g., on-line electrochemical mass spectrometry (OEMS)
  • Research focus on proton-exchange membrane fuel-cells (PEMFC's) and alkaline H2-fuel cells
  • Synthesis and characterization of HOR and ORR catalysts, e.g. Ru@Pt core-shell nanoparticles
  • Investigation of transport parameters in gas diffusion media
  • Characterization of catalyst activities and aging behavior in fuel cell test stations
  • Design and set up of a portable electrolysius/fuel cell test station
  • Investigation of the electrochemical characteristics of electrode materials, e.g., influence of the ionomer content
  • Aging testing of selected catalyst materials, e.g. IrO2
