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.

Nickel-rich layered oxides such as lithium nickel cobalt manganese oxide (NCM) are considered a suitable cathode material for high-energy lithium-ion batteries. However, the high nickel content leads to material stress, making it necessary to coat the cathodes. In a recent study, scientists from MEET Battery Research Center and the Institute of Materials Physics at the University of Münster have now investigated how this modification can be greatly simplified.
