▎ 摘 要
NOVELTY - Preparation of binder slurry involves mixing halogenated graphene nanoplatelets and polar solvents to form nanoplatelet slurry, and combining the slurry and binders to form binder slurry. Alternately, nanoplatelet slurry comprising halogenated graphene nanoplatelets in a polar solvent is combined with binders to form binder slurry. The nanoplatelets comprise graphene layers (a) free from any element or component other than sp2 carbon, and defect-free graphene layers (b). The total content of halogen in the nanoplatelets is 5 wt.% or less calculated as bromine. USE - Preparation of binder slurry for electrode used in energy storage device (all claimed) e.g. lithium ion battery. ADVANTAGE - The binder slurry capable of forming electrode having improved conductivity is prepared. The electrode provides energy storage device having excellent performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for energy storage device.
