dr. (E.M) Erik Kelder

Dr. Erik Kelder, returning from a Danish battery company, i.e. Danionics A/S, he worked on a patented Li-ion battery system using a novel densification technique, i.e. Magnetic Pulse Compaction (MPC).

The research aimed to synthesize and characterize Li-ion battery materials, components and cells capable of meeting improved properties in terms of performance.

Nano-structured ceramic materials played an important role here.

Among the stated objectives was a demonstration cell for down-hole application.

  • A casting process was used to fabricate electrodes.
  • Key aspects include analysis of electrode components on electronic and ionic conductivities.
  • X-ray and neutron diffraction (in-situ), NMR, SEM, particle size analysis, electrochemical impedance spectroscopy, cyclic voltammetry, charge/discharge testing (coulombic titration) were an integral part of the work.
  • Furthermore, an extension was made of various objectives of supporting industry such as stimulating the introduction of separator materials (DSM Solutech) and the development of critical technologies for high-temperature Li-ion batteries (Shell IEP).

An EC-project (with seven other partners) on a 42 Volt board-net Li-ion polymer battery is co-ordinated.

Till recently, he was managing director of the Delft Research Centre for Sustainable Energy headed by Prof. Schoonman.
