HELI – High Energy Lithium Sulphur Cells and batteries

Development of 3 different series of Li-S cell prototypes. The specific objectives are as follows

  • Energy density to 500 Wh/kg and specific power to 1000 W/kg during normal operation conditions;
  • Durability at least 5 years and a 1000 cycle lifetime within
  • Understand the ageing of Li-S cell prototypes and to postulate a mechanism which will predict Li-S cells and battery packs ageing in different climate environments;
  • To fully assess Li-S cells through several safety tests;
  • To bring Li-S technology to technology readiness levels (TRLs) ≥4.
  • the full discharge/full charge conditions;

INFLUENCE

Understanding and control of interfaces of a battery type based on Li-ion and Na-ion active materials: semi solid flow batteries (SSFB).

  • Optimization of the interfaces developing between the electrolyte and the electrochemically active material particles in fluid electrodes.

  • Understanding and control the mechanical and conductive behaviours of the slurries.

  •  

    The experimental work was accompanied by thorough modelling to understand the physical phenomena occurring at the microscopic scale, to derive scaling rules towards macro-scale and to enable design recommendations leading to optimal interface behaviour (size of anodic and cathodic compartments, geometry of collectors, etc.).

COBRA – Bateries sense Cobalt per a aplicacions als automòbils del futur

COBRA aims to develop a novel Cobalt-free Lithium-ion battery technology that overcomes many of the current shortcomings faced by Electrical Vehicle (EV) batteries. The proposed Li-ion technology will be demonstrated at TRL6 (battery pack level).

ECOTRIA

The aim of ECOTRIA project is to develop a new route from Metal recovery from secondary Li-Ion battery sources through bioleaching as key step

  • Characterize the battery cells, develop safe opening strategy and characterize anode and cathode components.
  • Asses the toxicity of cell components to culture media and evaluate the recovery yield
  • 90% recovery of Li & 65% recovery of Mn, Co & Ni in the experimental conditions.
  • níquel en les condicions experimentals.

Applied Research Projects

MARBEL – Manufacturing and Assembly of modular and Reusable EV Battery for Environment-friendly and Lightweight mobility

Development of a new compact, modular battery pack, designed from the start for its second use and recyclability, optimized weight and high performance, with longer life, greater energy efficiency in charging and use of energy, incorporating a robust and flexible system of management of the battery (Battery Management System), as well as of his ultrafast charge.

GTA BATT

Identification of the conflicting points in the fields of the cell, the module and the set of batteries, in order to adapt the possible improvement of the battery for the first and second useful life, as well as the determination of the best way of limit the effect of temperature on battery age by means of a cooling system or other type of technology.
The project also measured the performance of the cells in different scenarios, which could help identify the best operating conditions for a specific battery.

BATTMAN

BATTMAN was a Spanish collaborative project participated by EURECAT. Its main goal was to develop a new battery pack functionality. Increasing demand and future perspectives for electric mobility require the implementation of new functionalities for the batteries and energy storage systems.

BATTMAN developed a new manufacturing processes for lithium ion algorithms for the state of charge and state of health on the BMS of the batteries, , as well as a new way for test bench of batteries together.
