Cobalt-free battery now in test phase: a major milestone for the COBRA project

Cobalt-free battery now in test phase: a major milestone for the COBRA project

In the first week of June, several COBRA partners came together in Catalonia to carry out the End-of-Line testing of two complete battery pack prototypes. This marked a major milestone for the project that is developing cobalt-free electric vehicle (EV) battery packs. From this baseline, subsequent generations (Gen1, Gen2, GenX) will be developed from treated recycled active materials to the full battery pack – with improved performance. 

Partners present at commissioning week: AVL, Eurecat, Aentron, IREC, Applus+ IDIADA, Bax & Company, and Millor Battery

The battery commissioning 

After Millor Battery had assembled the battery pack, preliminary calibration and testing were performed. Subsequent testing procedures were completed at the nearby Eurecat facilities. Overall, the performed tests included: 

  1. IVT-S current sensor calibration
  2. Installation of the BCU
  3. Low voltage commissioning
  4. High voltage connection test
  5. BCU calibration

Firstly, at the Millor Batteries facilities, preliminary tests were performed to determine the battery pack’s proper functioning (e.g. BMS, connections, and sensors). Since one of the module’s MCUs reported a non-functioning cell, module-level testing was performed using multimeters. Once the alternative testing was completed, all the elements were performing correctly.

LC-BAT-5 Cluster workshop on Si-Gr electrodes

LC-BAT-5 Cluster workshop on Si-Gr electrodes

Last week, the LC-BAT-5 Cluster hosted its first in-person workshop at the Ångstroem Laboratory in Uppsala, Sweden.

The goal of the two-day workshop, organised by the HYDRA project, was to establish best practices for Si-Gr electrode research and agree on common reporting standards so that data published by each of the LC-BAT-5 projects (COBRA, 3beLiEVe, SeNSE & HYDRA) can be reusable and interoperable.

A total of 50 people attended the workshop (25 in-person and 25 virtual) hailing from 19 institutes spanning research and industry, each representing one or more of the four LC-BAT-5 projects.

COBRA: IREC, Uppsala University, CIDETEC, Solvionic, and Resitec.
3beLiEVe: Customcells Holding Gmbh, CIC energiGUNE, AIT, Vianode, Topsoe, and Arkema.
SeNSE: Empa, MEET, FZJ, and Enwires.
HYDRA: SINTEF, Uppsala University, ICSI, Vinode, Vianode, UCL, Solvionic, and POLITO.

Each project led a session of 1.5 hours on a different topic related to electrode research.

SeNSE explored methods of electrode preparation, COBRA led the discussion on electrolyte composition, HYDRA explored electrochemical operating parameters and 3beLiEVe focused on cycling stability and capacity fade mitigation.

The LC-BAT-5 Cluster was formed in 2020 to take advantage of synergies in communication, dissemination and technical matters. Together we are working on next-generation lithium-ion batteries made in Europe.
