Introduction

The SOLiDIFY project proposes a unique manufacturing process and solid-electrolyte material to fabricate Lithium-metal solid-state batteries – known as Gen. 4b on the EU battery roadmap. The concept is based on a solid nanocomposite electrolyte or nano-SCE. It is made by a sol-gel reaction which is used advantageously for a liquid-tosolid approach in the fabrication of the composite cathode and the solid-electrolyte separator. The general strategy to reach the target energy density of 1200Wh/L (400Wh/kg) in 20 minutes charging time is:

  1. enabling the integration of high-energy NMC active materials and
  2. development of new electrode architectures for high mass loading and enabled by the liquid-to-solid approach.

An added imposed challenge is a water-based cell assembly process. To this end, suitable protection of the high-energy NMC powder with ALD thin-film coatings is pursued. Finally, thin lithium foils with protective artificial interphase coatings will be developed for lamination on the nano-SCE separator.
