The overarching goal of RESiLiTE

Is to improve the robustness, sustainability and value proposition of battery packs for automotive vehicles, thus increasing the acceptance of end users on the mass-market.

This will be achieved mainly through safety improvements, increase of the fast-charging capability, and energy efficiency gains which will reduce the range loss in winter.

Length of the project: 36 months (starting in Jully 2025)

This project aims to integrate large format cylindrical cells (46xx, like 4680, 4695, etc.) employed by major car manufacturers worldwide within a novel thermoplastic battery housing.

This will allow to reduce the weight of the battery pack by up to 35%with respect to State of the Art (SotA) aluminium enclosures, thereby increasing the energy density.

Higher C-rate capability will be granted through a cost-effective and high-performance thermal management system integrated into the housing.

Redundancy in a higher safety level compared to the state of the art will be achieved not only by mechanical features but also by an advanced diagnostic systems and controls.

Objectives

The RESiLiTE project will develop a robust battery system, focusing on

High energy density at pack level

High energy density through a Cell-to-Pack approach

Safety by design

Cost-effective, No-Thermal Propagation concept & early diagnostics.

Operation performance

High cooling performance to allow 10%-80% fast-charging within 10 minutes.

Sustainability

High energy efficiency for extended operative ambient temperatures.

Fast charging

Improve the sustainability of battery packs via sustainable housing materials, and enhanced recyclability.

1

The project focusses on the measures necessary to achieve the percentual increase in energy density for cells with a 4695 cylindrical form-factor, independently from battery cell chemistry and thus their cell-level energy density values. A gravimetric packaging efficiency of 75% is aimed. With the cells considered in this project, a gravimetric energy density of 220 Wh/kg (+14%) and a volumetric energy density of 395 Wh/L (+26%) are targeted.

2

The objective of this project is to improve existing No-TP concepts with a focus on resilience of the concept, and cost-minimization.

3

Achieve a charging current corresponding to at least 4.5C, which represents a fast-charging time of about 9 minutes for a SoC variation from 10% to 80%.

4

Improve cycle life, operational performance and reduce load on thermal management system in extreme ambient temperature conditions.

5

Improve sustainability on three key areas: Reduce, Reuse, and Recycle

Expected impacts

  • Safe and cost-effective battery system
  • Improvement of the fast-charging capability
