SOLIDBAT

Solid-state battery

Characteristics

Growing energy demand and continued reliance on fossil fuels have intensified climate change, as reflected in the rise of global average temperatures. Road transport produces about three quarters of transport-related greenhouse gas emissions, making its decarbonization essential for climate neutrality. Battery electric vehicles (BEVs) are a key solution. In this context, SOLIDBAT develops an advanced solid-state battery technology for the automotive sector, targeting high energy density (400 Wh/kg, 1000 Wh/L), fast charging, long lifetime, and improved safety. The project advances tools for cell design with nickel-rich NMC cathode, lithium metal anode, and conductive hybrid gel polymer electrolyte formed in situ. Scalable manufacturing compatible with current lithium-ion processes supports faster market adoption while reducing material use and enabling more sustainable production

Result to be enhanced

SOLIDBAT impact can be divided into three main pillars:
• AD-HOC MATERIALS AND INTERFACES DESING DELIVERING A RELIABLE SSB TECHNOLOGY: The selection of solid-state cell components and architecture meeting, by the end of the project, all performance indicators at ambient and operational temperatures necessary for mobility.
• PROTOTYPES DEVELOPMENT AT RELEVANT INDUSTRIAL ENVIRONMENT: Cell manufacturing processes which allow the fabrication of performant, reliable, sustainable, and affordable solid-state cells, demonstrated at industrial pilot level, with a competitive cost towards 75 €/kWh at pack level by 2030.
• SUSTAINABILITY: Optimised environmental footprint of cell materials (carbon footprint, quantity of metals). Cell materials and designs which are compatible with a recycling process that respects the requirements as put forward in the Batteries Regulation.

Why is it important?

Competitive and sustainable batteries are urgently needed to accelerate the transition towards a climate-neutral economy, industry, and society. SOLIDBAT is expected to boost the introduction of Gen 4b technology into the market, surpassing the key performance indicators of current LIBs in the market while maintaining the intrinsic safety of solid-state technology.
