To recover phosphate from existing sources such as wastewater or farm manure and reuse it in lithium-ion batteries, MEET Battery Research Center at the University of Münster initiated the project SuSyPhos (short for: Sustainable Synthesis and Recycling of Phosphorus-containing Materials in Lithium-Ion Batteries).

Modifying the particles of nickel-rich lithium-nickel-cobalt-manganese-oxide (NCM) cathodes is an effective method to increase cycle life of lithium-ion batteries. As part of a German-Taiwanese research collaboration, scientists from the University of Münster and the National Taiwan University of Science and Technology have now systematically compared polycrystalline and ‘single-crystal’-NCM.

Nickel-rich layered oxides such as lithium nickel cobalt manganese oxide (NCM) are considered a suitable cathode material for high-energy lithium-ion batteries. The direct recycling of this material is an important step towards further increasing the sustainability of these cell systems. In contrast to conventional recycling, the material from old batteries is not broken down into its individual components and re-synthesized, but the aged materials are rejuvenated and reused directly in cell construction.

A sustainable and degradable alternative to per- and polyfluorinated alkyl substances, which are often used as electrode binders, are biopolymers, especially polysaccharides. In a recent study, MEET scientists investigated the extent to which these sugar groups can be used as functionalized binders to enable the aqueous processing of nickel-rich lithium-nickel-cobalt-manganese oxides as cathodes in high-energy lithium-ion batteries.
