Internal UGent project

Originating from the Industrial Research cluster SET

But broader scope

Broad UGent-wide explorative study to determine

– UGent expertise applicable in the field of energy storage

– UGent expertise coupled to the re-use of CO2

CAPTURE this: inspiring UGent research on energy storage

Opportunities:

Optimise the mechanical structure

Optimise the battery materials (cathode/electrode/electrolyte)

UGent expertise: composite materials Prof Joris Degrieck, Wim Van Paepegem

FEM tools: structural design (fatigue and impact)

Material characterisation

Structural batteries

Opportunities:

Optimise the mechanical structure

Optimise the battery materials (cathode/electrode/electrolyte)

UGent expertise batteries: Prof Christophe Detavernier, (SBO-SOS-Lion project, coord. IMEC)

Atomic Layer Deposition (ALD)

– Very thin uniform layers with perfect step coverage

– Deposit anode/electrolyte/cathode stack on 3D subst.

Battery characterisation

– Argon-filled gloveboxes

– Thin-film Li-ion batteries & powder batteries.

– Potentiostat/galvanostat (cyclic voltammetry,

galvanostatic charge-discharge).

Unique setup for in-situ XRD during battery testing

Excess electrical energy products

E.g. CH4 production

E.g. on-site NaOH production for cleaning

Capronic acid production from waste streams

Characteristics and challenges

Don’t store the electrical energy, but store the end-product

One-way storage: no back-conversion to electricity

Membrame technology?

Tunability? to allow for max. integration in the grid

Thermal storage based on metal foam
