About the project

SOLIDBAT aims to demonstrate a TRL6 solid-state battery (SSB) technology for EVs, combining high performance, safety, and sustainability. The goal is 500 cycles at 80% DoD, >400 Wh/kg, 1000 Wh/L, and a cost of 75 €/kWh by 2030. Key innovations include digital design tools, a water-processable nickel-rich NMC cathode, a 3D-textured lithium metal anode, a hybrid gel polymer electrolyte, and scalable manufacturing compatible with current lithium-ion technology. Sustainability is prioritized by reducing raw material use and eliminating organic solvents, ensuring a greener and cost-effective EV battery solution.
