Development of the all-solid-state batteries to overcome current battery technology challenges by ASTRABAT project

European-funded project ASTRABAT (GA No 875029), in collaboration with the technical partners including LOMARTOV and Elaphe Propulsion Technologies Ltd, has published preliminary results on applying certifications to all-solid-state battery prototypes.

The project aims to find optimal solid-state cell materials, components, and architecture mass-produced to meet electric vehicle market demands. However, these batteries technologies face numerous challenges that the consortium team pretends to solve.

The current constraints of Li-ion batteries are limited energy density and safety issues related to fire hazards and toxic gasses discharge in case of a thermal runaway. ASTRABAT responds to these needs and develops a Li-ion battery with a longer life cycle, more extensive operating temperature range, lower costs, and sufficient energy and power density to power the expected vehicle autonomy of 500km.

The project focuses on bringing all-solid Li-ion batteries to a higher technology readiness level for mass scale usage, complying with all regulations, standards, and certifications aspects where LOMARTOV and Elaphe play a pivotal role.

In recently published results on the Innovation News Network, the authors focus on and describe the main aspects in terms of:

  • Li-ion battery components: introducing the core of the Li-ion battery and its main components such as cathode, anode, electrolyte and separator and presenting their configuration architecture and functionality (led by DAIKIN and Fraunhofer).
  • Requirements for ASTRABAT’s all-solid-state battery prototype: determining the main regulation, law, and directives that apply to batteries for electric mobility, including the leading standards concerning safety requirements and test procedures beyond others. To respond to these requirements, extensive battery testing will be completed by CEA, LEITAT and Elaphe.
  • Analysing the Li-ion battery environmental impact: mentioning the environmental impact analysis through the whole production and manufacturing cycle, led by LOMARTOV. This activity closely considers the new proposal for a regulation concerning batteries and waste batteries.

In conclusion, the published results summarise the ASTRABAT project development on all-solid-state batteries aligned with the upcoming regulation aspects, which will be crucial to ensure entirely successful and sustainable marketability of the new cell.
