Versatile printed solutions for a safe and
high-performance battery system

What is Versaprint?

Versaprint is a 3-year Horizon project that brings innovation to batteries in the transport sector, improving their safety, manufacturability, sustainability, performance, and lifetime. Its main goal is to boost the circular economy and the cost-effectiveness of the battery value chain.
By 2D/3D printing on the cell or module components, VERSAPRINT offers technical solutions (Building Blocks – BBs) that contribute to tackling safety issues, enhancing performance, and decreasing cost and environmental impact. These versatile solutions are adaptable to different types of cell formats (prismatic or pouch) and will not be chemistry-dependant.

Specific objectives of the project

Improve the anticipation and mitigation of safety issues over the battery lifecycle
Increase performance at battery system level
Decrease battery system environmental footprint
Support decision making for next generation battery systems
Support decision making for next generation battery systems

At cell level

At cell level, VERSAPRINT improves safety and performance by:

  • providing thermal regulation via printed micro-channels that carry a cooling fluid on the cell surface and reduce the risk of Thermal Runaway, increasing density and lifetime (BB1)
  • improving the system thermal and safety management through printed sensors that monitor the temperature and detection of H2 (BB2)

At cells unit level

At cells unit level, VERSAPRINT targets safety, performance, and circularity by:

  • adding thermal dissipation, electrical shunt and safe dismantling functions on busbars via multi-functional designs (BB3)
  • allowing easy and safe dismantling and re-manufacturing of batteries through alternative solutions, including a non-welded busbar (BB4)

At module level

At module level, VERSAPRINT targets safety, performance, and environmental footprint by:

  • lowering the casing’s weight, without losing its capability to contain Thermal Runaway and ensuring good recycling rate by using Self-Reinforced Polymer (SRP) (BB5)
  • providing an advanced thermal/fire response by adding recyclable Phase Change Material and Flame Retardants (PCM/FR) to polymeric components at most critical locations (BB6)
  • controlling the gas/fire released during a Thermal Runaway by cooling and evacuating exhaust gases safely thanks to an integrated exhaust gas management system (BB7)
