WG 3: Application of batteries

phone on fireAmong the available energy storage technologies, Lithium-based batteries have detached as one of the few solutions, which are able to successfully meet the requirements imposed by both electricity grids and transportation sectors. This has become possible thanks to recent developments of Lithium batteries based on new and/or improved materials (e.g., NMC, LTO etc.), which have resulted in batteries with high performance (e.g., high power capability), long lifetime (e.g., 20 years/ 16 000 cycles), and increased safety. Nevertheless, it is well known that the performance of batteries (capacity and power) are degrading in time during operation (both idling and cycling). Consequently, many times the end users face performance-degradation uncertainties, when they select, size and operate their Lithium-ion batteries based systems. These uncertainties could to some extent mitigated by lifetime testing and lifetime estimation of the batteries.


This workshop will cover, but is not limited to, the following topics:

  • Lifetime testing and modelling are known to be time and resource demanding processes; thus, do we really need them (except from pure research perspective) or lifetime information, which is available in the battery datasheet is enough?
  • Are the Lithium-ion battery lifetime models developed in laboratory applicable in real life, or are they to complicated, not accurate enough?
  • How much battery degradation knowledge is transferable from one chemistry to the other?
  • Most of the research studies are focusing on capacity degradation and omitting the power capability decrease; How should be defined the end-of-life (EOL) criterion for power capability (e.g., for capacity fade we use and EOL criterion of 20%)?
  • Is it techno-economical feasible to use Lithium-ion battery with a capacity fade higher than 20%? In which applications?

The actions taken by the group could be to set up regular (e.g., on a yearly basis) workshops on the topic of “Battery Degradation” and strengthen the collaboration between academia and industry.
