NMC955 cathode for all-solid-state lithium batteries: PVDF-free synthesis production

The global push for electrification and the demand for higher energy density devices have driven both industry and academia to explore and advance traditional battery technology. The PULSELiON European project is dedicated to making significant contributions to the development of all-solid-state batteries, which can overcome the limitations of conventional Li-ion batteries, although they are not yet manufactured on a large scale. The project will use pulse laser deposition (PLD) techniques to produce anode and electrolyte materials, and conventional wet processing methods for the cathode materials. This approach aims to foster wide-scale development. The research centers on a nickel-rich NMC955 cathode with minimal cobalt, representing the forefront of NMC technology, combined with an all-solid-state sulfide-based electrolyte, Li6PS5Cl (LPSCl), which shows great promise for applications in the transportation sector [1], [2]. This poster presents results from all-solid-state cells containing an NMC955 cathode produced using a sustainable synthesis method that excludes PVDF and employs SBR. It demonstrates high-capacity retention without the need for additional interlayers, applied pressure, or specific temperature control during electrochemical cycling. Additionally, the results presented here will highlight the importance of a customized cycling regimen to ensure enhanced, stable performance and an extended cycle life [3].
