About

SOLIDBAT aims to demonstrate a TRL6 solid-state battery (SSB) technology that meets EV performance, cost, and safety requirements while ensuring sustainability. With a specialized consortium covering the battery value chain, the project targets 500 cycles at 80% DoD, >400 Wh/kg, 1000 Wh/L, and a cost of 75 €/kWh by 2030. SOLIDBAT prioritizes EU standards for sustainability, safety, and recyclability in cell components and manufacturing.

Vision & Concept

The rising energy demand and reliance on fossil fuels have accelerated climate change, with road transport contributing three-quarters of transport-related GHG emissions. Decarbonizing this sector is key to climate neutrality, with BEVs playing a crucial role. SOLIDBAT addresses this challenge by developing a disruptive solid-state battery (SSB) technology focused on high energy density, fast charging, long life, and safety.

Technical approach

SOLIDBAT develops high-energy-density SSBs (400 Wh/kg, 1000 Wh/L) with fast charging, long life, and safety. Key innovations include digital tools for cell design, a water-processable nickel-rich NMC cathode, a 3D-textured lithium metal anode, a hybrid gel polymer electrolyte (HGPE), and scalable manufacturing compatible with lithium-ion technology. The project also minimizes raw material use and eliminates organic solvents for greener processing.
